micrel, inc. ksz8463ml/rl/fml/frl june 11, 2014 28 revision 1.0 functional description the ksz8463 is a highly - integrated networking device that incorporates a layer - 2 switch, two 10bt/100bt physical layer transceivers (phys) and associated mac units, one mii/rmii interface on a third accessible mac unit, and contains key ieee 1588 precision time protocol (ptp) features. the ksz8463 operates in a managed mode. in managed mode, a host processor can access and control all phy, switch, mac, and ieee 1588 related registers in the ksz8463 via the high - speed spi bus, or partial control via the miim (mdc/mdio) interface. physical si gnal transmission and reception are enhanced through the use of analog circuits in the phy that make the design more efficient and allow for low power consumption. b oth power management and energy - efficient ethernet (eee) are designed to save more power wh ile the device is in idle state. the ksz8463 is fully compliant to ieee802.3u standards. physical (phy ) block 100base - tx transmit the 100base - tx transmit function performs parallel - to - serial conversion, 4b/5b coding, scrambling, nrz - to - nrzi conversion, and mlt3 encoding and transmission. the circuitry starts with a parallel - to - serial conversion, which converts the m ii data from the mac into a 125 mhz serial bit stream. the data and control stream is then converted into 4b/5b coding, followed by a scrambler. the serialized data is further converted from nrz - to - nrzi format, and then transmitted in mlt3 current output. an external 6.49k ? (1%) resistor for the 1:1 transformer ratio sets the output current. the output signal has a typical rise/ fall time of 4 ns an d complies with the ansi tp - pmd standard regarding amplitude balance, overshoot, and timing jitter. the wave - shaped 10base - t output driver is also incorporated into the 100base - tx driver. 100base - tx receive the 100base - tx receiver function performs adaptiv e equalization, dc restoration, mlt3 - to - nrzi conversion, data and clock recovery, nrzi - to - nrz conversion, de - scrambling, 4b/5b decoding, and serial - to - parallel conversion. the receiving side starts with the equalization filter to compensate for inter - symb ol interference (isi) over the twisted pair cable. since the amplitude loss and phase distortion is a function of the cable length, the equalizer has to adjust its characteristics to optimize performance. in this design, the variable equalizer makes an ini tial estimation based on comparisons of incoming signal strength against some known cable characteristics, and then tunes itself for optimization. this is an ongoing process and self - adjusts against environmental changes such as temperature variations. nex t, the equalized signal goes through a dc restoration and data conversion block. the dc restoration circuit is used to compensate for the effect of baseline wander and to improve the dynamic range. the differential data conversion circuit converts the mlt3 format back to nrzi. the slicing threshold is also adaptive. the clock re covery circuit extracts the 125 mhz clock from the edges of the nrzi signal. this recovered clock is then used to convert the nrzi signal into the nrz format. this signal is sent thro ugh the de - scrambler followed by the 4b/5b decoder. finally, the nrz serial data is converted to an mii format and provided as the input data to the mac. scrambler/de - scrambler (100base - tx only) the purpose of the scrambler is to spread the power spectrum of the signal to reduce electromagnetic interference (emi) and baseline wander. transmitted data is scrambled through the use of an 11 - bit wide linear feedback shift register (lfsr). the scrambler generates a 2047 - bit non - repetitive sequence. then the rec eiver de - scrambles the incoming data stream using the same sequence as at the transmitter. pll clock synthesizer (recovery) the device incorporates an internal pll clock synthesizer for data recovery as well as for generating various clocks used in the dev ice. refer to the device clocks section for details of this area.
micrel, inc. ksz8463ml/rl/fml/frl june 11, 2014 29 revision 1.0 100base - fx operation fiber mode is available only on the ksz8463fml and ksz8463frl devices. 100base - fx operation is similar to 100base - tx operation except that the scrambler/de - scrambler and mlt3 encoder/decoder are bypassed on transmission and reception. in this fiber mode, the auto - negotiation feature is bypassed and auto mdi/mdix is disabled s ince there is no standard that supports fiber auto - negotiation and auto mdi/mdix mode. the fiber port must be forced to either full - duplex or half - duplex mode. all ksz8463 devices are in copper mode (10b ase - t / 100b ase - tx) when reset or powered on. fiber mode is enabled by clearing bits [7:6] in the cfgr register (0x0d8 - 0x0d9). each port is individually configurable. bit [13] in the dsp_cntrl_6 register (0x734 - 0x735) should also be cleared if either (or both) ports are set to fiber mode. 100base - fx signal d etection in 100base - fx operation, the fiber signal detect input s fxsd1 and fxsd2 are usually connected to the signal detect (sd ) output pin of the fiber transceiver . when fxsd is low , no fiber signal is detected and a far - end fault (fef) is generated. when fxsd is high , the fiber signal is detected. to ensure proper operation, a resistive voltage divider is recommended to adjust the fiber transceiver sd output voltage swing to match the fxsd pin?s input voltage threshold. alternatively, the user may choose not to implement the fef feature. in this case, the fxsd input pin is tied high to force 100base - fx mode. in copper mode, and on the ksz8463ml and ksz8463rl, the fxsd pins are unused and should be pulled low . 100base - fx far - end fault a far - end fault (fef) occurs when the signal detection is logically false on the receive side of the fiber transceiver. the ksz8463fml/frl detects an fef when its fxsd input is below the f iber s ignal detect t hreshold . when an fef is detected, the ksz8463fm l/frl signals its fiber link partner that a fef has occurred by sending 84 1?s followed by a zero in the idle period between frames. by default, fef is enabled. fef can be disabled through register setting in p1cr4[12] and p2cr4[12]. 10base - t transmit the 10base - t driver is incorporated with the 100base - tx driver to allow for transmission using the same magnetics. they are internally wave - shaped and pre - emphasized into outputs with typical 2.3v amplitude. the harmonic contents are at least 27db below the fu ndamental frequency when driven by an all - ones manchester - encoded signal. 10base - t receive on the receive side, input buffers and level detecting squelch circuits are employed. a differential input receiver circuit a nd a phase - locked loop (pll) perform the decoding function. the manchester - encoded data stream is separated into clock signal and nrz data. a squelch circuit rejects signals with levels less than 400mv or with short pulse widths to prevent noise at the rxp1 or rxm1 input from falsely triggering the decoder. when the input exceeds the squelch limit, the pll locks onto the incoming signal and the ksz8463 decodes a data frame. the receiver clock is maintained active during idle periods in between data reception.

micrel, inc. ksz8463ml/rl/fml/frl june 11, 2014 32 revision 1.0 figure 3 . auto - negotiation and parallel operation linkmd ? cable diagnostics the ksz8463 linkmd uses time domain reflectometry (tdr) to analyze the cabling plant for common cabling problems such as open circuits, short circuits, and impedance mismatches. linkmd works by sending a pulse of known amplitude and duration down the mdi and mdi - x p airs and then analyzes the shape of the reflected signal. timing the pulse duration gives an indication of the distance to the cabling fault with a maximum distance of 200m and an accuracy of 2m. internal circuitry displays the tdr information in a user - r eadable digital format in register p1scslmd[8:0] or p2scslmd[8:0]. note : c able diagnostics are only valid for copper connections . f iber - optic operation is not supported. access linkmd is initiated by accessing register p1scslmd (0x07c) or p2scslmd (0x094), the phy special control/status & linkmd register. usage before initiating linkmd, the value 0x8008 must be written to the ana_cntrl_3 register (0x74c ? 0x74d). this needs to be done once (after power - n reset) , but does not need to be repeated for each ini tiation of linkmd. auto - mdix must also be disabled before using linkmd. to disable auto - mdix, write a ?1? to p1cr4[10] or p2cr4[10] to enable manual control over the pair used to transmit the linkmd pulse. the self - clearing cable diagnostic test enable bit , p1scslmd[12] or p2scslmd[12], is set to ?1? to start the test on this pair.
micrel, inc. ksz8463ml/rl/fml/frl june 11, 2014 33 revision 1.0 when bit p1scslmd[12] or p2scslmd[12] returns to ?0?, the test is completed. the test result is returned in bits p1scslmd[14:13] or p2scslmd[14:13] and the distance is returne d in bits p1scslmd[8:0] or p2scslmd[8:0]. the cable diagnostic test results are as follows: ? 00 = valid test, normal condition \ ? 01 = valid test, open circuit in cable ? 10 = valid test, short circuit in cable ? 11 = invalid test, linkmd? failed if p1scslmd[14: 13] or p2scslmd[14:13] is ?11?, this indicates an invalid test . this occurs when the ksz8463 is unable to shut down the link partner. in this instance, the test is not run, as it is not possible for the ksz8463 to determine if the detected signal is a ref lection of the signal generated or a signal from another source. cable distance can be approximated by utilizing the following formula: ? p1scslmd[8:0] x 0.4m for port 1 cable distance ? p2scslmd[8:0] x 0.4m for port 2 cable distance this constant (0.4m) may be calibrated for different cabling conditions, including cables with a velocity of propagation that varies significantly from the norm. on - chip termination resistors using the ksz8463 reduces board cost and simplifies board layout by using on - chip termina tion resistors for the rx/tx differential pairs , eliminating the need for external termination resistors in copper mode . the internal chip termination and biasing provides significant power savings when compared with using external biasing and termination resistors. loopback support the ksz8463 provides two loopback modes . o ne is near - end (remote) loopback to support remote diagnosing of failures on line side, and the other is far - end loopback to support local diagnosing of failures through all blocks of th e device. in loopback mode, the speed of the phy port will be set to 100base - tx full - duplex mode. far - end loopback far - end loopback is conducted between the ksz8463 ?s two phy ports. the loopback path starts at the ? o riginating ? phy port?s receive inputs (r xp/rxm), wraps around at the ?loopback? phy port?s pmd/pma (physical media dependent/physical media attachment) , and ends at the ?originating? phy port?s transmit outputs (txp/txm). bit[8] of registers p1cr4 and p2cr4 is used to enable far - end loopback fo r port s 1 and 2, respectively. as an alternative, bit [14] of registers p1mbcr and p2mbcr can be used to enable far - end loopback. the far - end loopback path is illustrated in the figure 4 . near - end (remote) loopback near - end (remote) loopback is conducted at either phy port 1 or phy port 2 of the ksz8463 . the loopback path starts at the phy port?s receive inputs (rxpx/rxmx), wraps around at the same phy po rt?s pmd/pma, and ends at the same phy port?s transmit outputs (txpx/txmx). bit[1] of registers p1phyctrl and p2phyctrl is used to enable near - end loopback for port s 1 and 2, respectively. as an alternative, bit [9] of registers p1scslmd and p2scslmd can be used to enable near - end loopback. the near - end loopback paths for port 1 and port 2 are illustrated in figure 4 .

micrel, inc. ksz8463ml/rl/fml/frl june 11, 2014 35 revision 1.0 mac (media access controller) block mac operation the ksz8463 strictly abides by ieee 802.3 standards to maximize compatibility. additionally, there is an added mac filtering function to filter unicast packets. the mac filtering function is useful in applications such as voip where restricting certain pac kets reduces congestion and thus improves performance. address lookup the internal dynamic mac address lookup table stores mac addresses and their associated information. it contains a 1k entry unicast address learning table plus switching information. the ksz8463 is guaranteed to learn 1k addresses and distinguishes itself from hash - based lookup tables, which , depending on the operating environment and probabilities, may not guarantee the absolute number of addresses they can learn. learning the internal l ookup engine updates the dynamic mac address table with a new entry if the following conditions are met: ? the received packet's source address (sa) does not exist in the lookup table. ? the received packet has no receiving errors , and the packet size is of l egal length. the lookup engine inserts the qualified sa into the table, along with the port number and time stamp. if the table is full, t he oldest entry of the table is deleted to make room for the new entry. migration the internal lookup engine also mon itors whether a station has moved. if a station has moved, it updates the table accordingly. migration happens when the following conditions are met: ? the received packet's sa is in the table but the associated source port information is different. ? the rece ived packet has no receiving errors , and the packet size is of legal length. the lookup engine updates the existing record in the table with the new source port information. aging the lookup engine updates the time stamp information of a record whenever t he corresponding sa appears. the time stamp is used in the aging process. if a record is not updated for a period of time, the lookup engine removes the record from the table. the lookup engine constantly performs the aging process and continuously removes aging records. the aging period is about 300 seconds ( 75 seconds). this feature can be enabled or disabled through global register sgcr1[10]. forwarding the ksz8463 forwards packets using the algorithm that is depicted in the following flowcharts. figure 5 shows stage one of the forwarding algorithm where the search engine looks up the vlan id, static table, and dynamic table for the destination address, and comes up with ?port to forward 1? (ptf1). ptf1 is then further modified by spanning tree, igmp snooping, port mirroring, and port vlan processes to come up with ?port - to - forward 2? (ptf2), as shown in fig ure 6 . the packet is sent to ptf2. the ksz8463 will not forward the following packets: ? error packets: these include framing errors, frame check sequence (fcs) errors, alignment errors, and illegal size packet errors. ? ieee802.3x pause frames: ksz8463 intercepts these packets and performs full duplex flow control accordingly. "local" packets: based on destination address (da) lookup. if the destination port from the lookup table matches the p ort from which the packet originated, the packet is defined as "local."

micrel, inc. ksz8463ml/rl/fml/frl june 11, 2014 38 revision 1.0 flow control the ksz8463 supports standard 802.3x flow control frames in both the transmit and receive directions . in the receiv e direction , if a pause control frame is received on any port , the ksz8463 will not transmit the next normal frame on that port until the timer, specified in the pause control frame, expires. if another pause frame is received before the current timer expi res, the timer will then update with the new value in the second pause frame. during this period (while it is flow controlled), only flow control packets from the ksz8463 are transmitted. in the transmit direction , the ksz8463 has intelligent and efficient ways to determine when to invoke flow control and send pause frames . the flow control is based on availability of the system resources, including available buffers, available transmit queues and available receive queues . the ksz8463 issues a pause frame c ontaining the maximum pause time defined in ieee standard 802.3x. once the resource is freed up, the ksz8463 sends out another flow control frame with zero pause time to turn off the flow control (turn on transmission to the port). a hysteresis feature is provided to prevent the flow control mechanism from being constantly activated and deactivated. half - duplex backpressure a half - duplex backpressure option (non - ieee 802.3 standards) is also provided. the activation and deactivation conditions are the same as in full - duplex mode. if backpressure is required, the ksz8463 sends preambles to defer the other stations' transmission (carrier sense deference). to avoid jabber and excessive deference (as defined in the 802.3 standard), after a certain time, the ksz 8463 discontinues the carrier sense and then raises it again quickly. this short silent time (no carrier sense) prevents other stations from sending out packets thus keeping other stations in a carrier sense deferred state. if the port has packets to send during a backpressure situation, the carrier sense type backpressure is interrupted and those packets are transmitted instead. if there are no additional packets to send, carrier sense type backpressure is reactivated again until chip resources free up. if a collision occurs, the binary exponential back - off algorithm is skipped and carrier sense is generated immediately, thus reducing the chance of further collision and carrier sense is maintained to prevent packet reception. to ensure no packet loss in 10b ase - t or 100base - tx half - duplex mode, the user must enable the following bits: ? aggressive back off (bit [8] in sgcr1) ? no excessive collision drop (bit [3] in sgcr2) ? back pressure flow control enable (bit [11] in p1cr2/p2cr2) note : these bits are not set in default, since this is not the ieee standard.
micrel, inc. ksz8463ml/rl/fml/frl june 11, 2014 39 revision 1.0 broadcast storm protection the ksz8463 has an intelligent option to protect the switch system from receiving too many broadcast packets. as the broadcast packets are forwarded to all ports except the sourc e port, an excessive number of switch resources (bandwidth and available space in transmit queues) may be utilized. the ksz8463 has the option to include ?multicast packets? for storm control. the broadcast storm rate parameters are programmed globally, an d can be enabled or disabled on a per port basis in p1cr1[7] and p2cr1[7]. the rate is based on a 67ms interval for 100bt and a 670 ms interval for 10bt. at the beginning of each interval, the counter is cleared to zero and the rate limit mechanism starts t o count the number of bytes during the interval. the rate definition is described in sgcr3[2:0][15:8]. the default setting is 0x63 (99 decimal). this is equal to a rate of 1%, calculated as follows: 148,800 frames/sec 67 ms/interval 1% = 99 frames/interval (approx.) = 0x63 note : 148,800 frames/sec is based on 64 - byte block of packets in 100base - t with 12 bytes of ipg and 8 bytes of preamble between two packets. port individual mac a ddress and source port filtering the ksz8463 can pr ovide individual mac addresses for port 1 and port 2. they can be set at registers 0x0b0h - 0x0b5h and 0x0b6 - 0x0bb. received packets can be filtered (dropped) if their source address matches the mac address of port 1 or port 2. this feature can be enabled by setting bits [11:10] in the p1cr1 or p2cr1 registers. one example of usage is that a packet will be dropped after it completes a full round trip within a ring network .

micrel, inc. ksz8463ml/rl/fml/frl june 11, 2014 41 revision 1.0 rapid spanning tree support there are three operational s tates assigned to each port for rstp (discarding, learning, and forwarding): ? discarding ports do not participate in the active topology and do not learn mac addresses. ? discarding state: the state includes three states of the disable, blocking and listenin g of stp. ? port setting: xmit enable = ?0?, receive enable = ?0?, learning disable = ?1?. discarding state software action: the host processor should not send any packets to the port. the switch may still send specific packets to the processor (packets that match some entries in the static table with ?overriding bit? set) and the processor should discard those packets. when the port?s learning capability (learning disable = ?1?) is disabled, setting bits [ 10:9] in the sgcr8 register will rapidly flush th e port related entries in the dynamic mac table and static mac table. the processor is connected to port 3 via the host interface. address learning is disabled on the port in this state. learning state port s in ?learning s tates? learn mac addresses, but do not forward user traffic. learning state: only packets to and from the processor are forwarded. learning is enabled. port setting for learning state: transmit enable = ?0?, receive enable = ?0?, learning disable = ?0?. software action: the processor shou ld program the static mac table with the entries that it needs to receive (e.g., bpdu packets). the ?overriding? bit should be set so that the switch will forward those specific packets to the processor. the processor may send packet s to the port(s) in thi s state ( see ? tail tagging mode ? sub - section for details ). address learning is enabled on the port in this state. port s in ? forwarding states ? fully participate in both data forwarding and mac learning. forwarding state forwarding state: packets are forwarded and received normally. learning is enabled. port setting: transmit enable = ?1?, receive enable = ?1?, learning disable = ?0?. software ac tion: the processor should program the static mac table with the entries that it needs to receive (e.g., bpdu packets). the ?overriding? bit should be set so that the switch will forward those specific packets to the processor. the processor may send packe t s to the port(s) in this state ( see ? tail tagging mode ? sub - section for details ) . address learning is enabled on the port in this state. rstp uses onl y one type of bpdu called rstp bpdus. they are similar to stp c onfiguration bpdus with the exception of a type field set to ?version 2? for rstp and ?version 0? for stp, and a flag field carrying additional information. tail tagging mode the t a il t ag is on ly seen and used by the port 3 host interface, which should be connected to a processor. it is an effective way to retrieve the ingress port information for spanning tree protocol, igmp snooping, and other applications . b it s [ 1 : 0 ] in the one byte tail tagg ing are used to indicate the source/destination port in port 3. b its [ 3 : 2 ] are used for priority setting of the ingress frame in port 3 . other bits are not used. the tail t ag fe ature is enabled by setting bit[ 8 ] in the sgcr8 register. figure 7 . tail tag frame format

(or = ?0? with hop - by - hop next header = ?1? or ?58?) ? if sgcr2[12] = ?1?, ipv6 next header = ?43?, ?44?, ?50?, ?51?, or ?60?

(q0 and q1) ? bit[0], bit [8] = ?10? egress port can be split into four priority transmit queues. (q0, q1, q2 and q3) the four priority transmit queues is a new feature in the ksz8463 . queue 3 is the highest priority queue and queue 0 is the lowest priority queue. if a port 's transmit queue is not split, high priority and low priority packets have equal priority in the transmit queue. there is an additional option for every port via bits[15,7] in the p 1 itxqrcr1, p1txqrcr2 , p2txqrcr1, p2txqrcr2, p3txqrcr1, and p3txqrcr2 registers to select either always to deliver high priority packets first or use weighted fair queuing for the four priority queues scale by 8:4:2:1. port - based pri ority with port - based priority, each ingress port is individually classified as a specific priority level . all packets received at the high - priority receiving port are marked as high priority and are sent to the high - priority transmit queue if the correspo nding transmit queue is split. bits [4:3] of registers p1cr1, p2cr1, and p3cr1 are used to enable port - based priority for port s 1, 2, and the host port , respectively. 802.1p - based priority for 802.1p - based priority, the ksz8463 examines the ingress (incomin g) packets to determine whether they are tagged. if tagged, the 3 - bit priority field in the vlan tag is retrieved and used to look up the ?priority mapping? value, as specified by the register sgcr6. the ?priority mapping? value is programmable. figure 8 illustrates how the 802.1p priority field is embedded in the 802.1q vlan tag. figure 8 . 802.1p priority field format
micrel, inc. ksz8463ml/rl/fml/frl june 11, 2014 45 revision 1.0 802.1p - based priority is enabled by bit[5] of registers p1cr1, p2cr1, and p3cr1 for port s 1, 2, and the host port , respectively. the ksz8463 provides the option to insert or remove the priority tagged frame's header at each individual egress port . this hea der, consisting of the 2 bytes vlan protocol id (vpid) and the 2 bytes tag control information field (tci), is also referred to as the 802.1q vlan tag. tag insertion is enabled by bit[2] of registers p1cr1, p2cr1, and p3cr1 for port s 1, 2, and the host por t , respectively. at the egress port , untagged packets are tagged with the ingress port?s default tag. the default tags are programmed in register sets p1vidcr, p2vidcr, and p3vidcr for port s 1, 2, and the host port , respectively. the ksz8463 does not add t ags to already tagged packets. tag removal is enabled by bit[1] of registers p1cr1, p2cr1, and p3cr1 for port s 1, 2, and the host port , respectively. at the egress port , tagged packe ts will have their 802.1q vlan t ags removed. the ksz8463 will not modify u ntagged packets. the crc is recalculated for both tag insertion and tag removal. 802.1p priority field re - mapping this is a qos feature that allows the ksz8463 to set the ?user priority ceiling? at any ingress port . if the ingress packet?s priority field h as a higher priority value than the default tag?s priority field of the ingress port , the packet?s priority field is replaced with the default tag?s priority field. the ?user priority ceiling? is enabled by bit[3] of registers p1cr2, p2cr2, and p3cr2 for p ort s 1, 2, and the host port , respectively. diffserv - b ased priority diffserv - based priority uses the tos registers shown in the tos priority control registers . the tos priority control registers impl ement a fully decoded, 128 - bit differentiated services code p oint (dscp) register to determine packet priority from the 6 - bit tos field in the ip header. when the most significant 6 bits of the tos field are fully decoded, the resultant of the 64 possibilities is compared with the corresponding bits in the dscp register to determine priority. rate limiting sup port the ksz8463 suppor ts hardware rate lim iting from 64 kbp s to 99mbps (refer to ingress or egress data rate limits ), independently on the ?receive side? and on the ?transmi t side? as per port basis. for 10 - base t, a rate setting above 10mbps means the rate is not limited. on the receive side, the data receive rate for each priority at each port can be limited by setting up ingress rate control registers. on the transmit side, the data transmit rate for each priority queue at each port can be limited by setting up egress rate control registers. the size of each frame has options to include minimum interframe gap (ifg) or preamble byte, in addition to the data field (from packet da to fcs). for ingress rate limiting, ksz8463 provides options to selectively choose frames from all types, multicast, broadcast, and flooded unicast frames. the ksz8463 counts the data rate from those selected type of frames. packets are dropped at the ingress port when the data rate exceeds the specified rate limit. for egress rate limiting, the leaky b ucket algorithm is applied to each output priority queue for shaping output traffic. inter frame gap is stretched on a per frame base to generate smooth, non- burst egress traffic. the throughput of each output priority queue is limited by the egress rate specified. if any egress queue receives more traffic than the specified egress rate throughput, packets may be accumulated in the output queue and packet memory. after the memory of the queue or the port is used up, packet dropping or flow control will be triggered. as a result of congestion, the actual egress rate may be dominated by flow control/dropping at the ingress end, and may be therefore slightly l ess than the specified egress rate. to reduce congestion, it is a good practice to make sure the egress bandwidth exceeds the ingress bandwidth.

micrel, inc. ksz8463ml/rl/fml/frl june 11, 2014 47 revision 1.0 ieee 1588 precision time protocol (ptp) block the ie ee 1588 precision time p rotocol (ptp) provides a method for establishing synchronized time across nodes in an ethernet networking environment. the ksz8463 implements v2 (2008) of the ieee 1588 ptp specification. the ksz8463 3 - port switch implements the ieee 1588 ptp version 2 protocol. port 1 and port 2 can be programmed as either end - to - end ( e2e ) or peer - to - peer ( p2p ) transparent clock (tc) port s . i n addition , port 3 can be programmed as either slave or master ordinary clock (oc) port . ingress timestamp capture, egress timestamp recording, correction field update with residence time and link delay, delay turn - around time insertion, egress timestamp insertion, and checksum update are sup port ed . ptp frame filtering is implemented to enha nce overall system performance. delay adjustments are implemented to fine tune the synchronization. versatile event trigger outputs and timestamp capture inputs are implemented to meet various real time application requirements through gpio pins. the key f eatures of the ksz8463 implementation are as follows: ? both one - step and two - step transparent clock (tc) operations are sup port ed ? implementation of precision time clock per specification ? upper 16 bits of the second clock not implemented due to practical val ues of time ? both e2e and p2p tc are sup port ed on port 1 and port 2 ? both s lave and master oc are sup port ed on port 3 ? ptp m ulticast and u nicast frame are sup port ed ? trans port s of ptp over ipv4/ipv6 udp and ieee 802.3/ethernet are sup port ed ? both path delay request - response and peer delay mechanism are sup port ed ? precision time stamping of input signals on the gpio pins ? creation and delivery of clocks, pulses, or other unique serial bit streams on the gpio pins with respect to the precision tim e clock time. ieee 1588 defines two essential functions: the measurement of link and residence (switching) delays by using the delay_req/resp or pdelay_req/resp messages, and the distribution of time infor mation by using the sync/follow_ up messages. the 1588 ptp event messages are periodically sent from the g rand m aster in the network to all slave clock devices. link delays are measured by each slave node to all its link partners to compensate for the delay of ptp messages sent through the network . the 1588 ptp announce messages are periodically sent from the grandmaster(s) in the network to all slave clock devices. this information is used by each node to select a master clock using the ?best master clock? algorithm. 1588 ptp (version 2) defines two typ es of messages : event and general messages. these are summarized below and are sup port ed by the ksz8463: ? event messages (an accurate timestamp is generated at egress and ingress): ? sync (from m aster to s lave ) ? delay_req (from s lave to m aster ) ? pdelay_req (bet ween link partners for peer delay measurement) ? pdelay_resp (between link partners for peer delay measurement) general messages: ? follow_up (from master to slave) ? delay_resp (from master to slave) ? pdelay_resp_follow_up (between link partners for peer delay measurement) ? announce ? management ? signaling
micrel, inc. ksz8463ml/rl/fml/frl june 11, 2014 48 revision 1.0 ieee 1588 ptp clock types the ksz8463 sup port s the following clock types: ? ordinary clock (oc) is defined as a ptp clock with a single ptp port in a ptp domain. it may serve as a source of time such as a master clock, or it may be a slave clock which synchronizes to another master clock. ? end - to - end transparent clock (e2e tc) is defined as a transparent clock that sup port s the use of the end - to - end delay measurement mechanism b etween a slave clock and the master clock. in this method, the e2e tc intermediate devices do not need to be synchronized to the master clock and the end slave node is directly synchronized to the master clock. the e2e tc/sc slave intermediate devices can also be synchronized to the master clock. note that the transparent clock is not a real clock that can be viewed on an oscilloscope but rather it is a mechanism by which delay are accounted for when trans port ing information across and through physical netw ork nodes. ? peer - to - peer transparent clock (p2p tc for version 2) is defined as a transparent clock, in addition to providing ptp event transit time information. p2p tc also provides corrections for the propagation delay between nodes (link partners) by usi ng pdelay_req ( p eer delay request) and pdelay_resp ( p eer delay response). in this method, the p2p tc intermediate devices can be synchronized to the master clock. a transparent clock (tc) is not part of the master - slave hierarchy. instead, it measures the resident time which is the time taken for a ptp message t o traverse the node. the p2p tc then provides this information to the clock receiving the ptp message. in addition, the p2p tc measures and passes on the link delay of the receiving ptp message. note that the transparent clock is not a real clock that can be viewed on an oscilloscope but rather it is a mechanism by which delay are accounted for when trans port ing information across and through physical network nodes. ? master c lock is defined as a clock which is used as the reference clock for the entire syste m. the ksz8463 can operate as a master c lock if needed. however, the quality of the clock signal will be limited by the quality of the crystal or oscillator used to clock the device. note : p2p and e2e tcs cannot be mixed on the same communication path. ieee 1588 ptp one - step or two - step clock operation the ksz8463 sup port s either 1 - step or 2 - step clock operation. ? one - step clock operation : a ptp message (sync) exchange that provides time information using a single event message which eliminates the need for a follow_up message to be sent. this one - step operation will eliminate the need for software to read the timestamp and to send a follow_up message. ? two - step clock operation : a ptp messages (sync/follow_up) that provides time information using the combi nation of an event message and a subsequent general message. the follow_up message carries a pr ecise estimate of the time the s ync message was placed on the ptp communication path by the sending node . ieee 1588 ptp best master clock selection the ieee 1588 ptp specification defines an algorithm based on the characteristics of the clo cks and system topology called best master clock (bmc) a lgorithm. bmc uses a nnounce messages to establish the synchronization hierarchy. the algorithm compares data from two clo cks to determine the better clock. each clock device continuously monitors the announce messages issued by the current master and compares the dataset to itself. the software controls this process. ieee 1588 ptp system time clock the system time c lock (stc ) in ksz8463 is a readable or writable ti me source for all ieee 1588 ptp - related functions and contains three counters: a 32- bit counter for s econds, a 30- bit counter for n anoseconds and a 32 - bit counter for s ub- nanoseconds ( u nit s of 2 - 32 ns). figure 9 shows the ptp clock.
micrel, inc. ksz8463ml/rl/fml/frl june 11, 2014 49 revision 1.0 figure 9 . ptp system clock overview the stc is clocked (incremented by 40ns or updated with sub ns carry info) every 40ns by a derivative of the 125mhz derived clock. the 30 - bit nanosecond counter will be numerically incremented by 40ns every 40ns. there is another 3 - bit phase counter that i s designed to indicate one of the five sub phases (0ns, 8ns, 16ns, 24ns, or 32ns) within the 40ns period. this provides finer resolution for the various messages and timestamps. the overflow for the 30 - bit nanosecond counter is 0x3b9aca00 (109) and the ove rflow for the 32 - bit sub - nanosecond counter is 0xffffffff. the system time clock does not sup port the upper 16 - bits of the seconds field as defined by the ieee 1588 ptp version 2 which specifies a 48 - bit seconds field. if the 32 - bit seconds counter overfl ows, it will have to be handled by software. note that an overflow of the seconds field only occurs every 136 years. the seconds value is kept track of in the ptp_rtc_sh and ptp_rtc_sl registers (0x608 ? 0x60b). the nanoseconds value is kept track of in th e ptp_rtc_nsh and ptp_rtc_nsl registers (0x604 ? 0x607). the ptp_rtc_phase clock register (0x60c ? 0x60d) is initialized to zero whenever the local processor writes to the ptp_rtc_nsl, ptp_rtc_nsh, ptp_rtc_sl, and ptp_rtc_sh registers. during normal oper ation when the stc clock is keeping synchronized real time, and not while it is undergoing any initialization manipulation by the processor to get it close to the real time, the ptp_rtc_phase clock register will be reset to zero at the beginning of the cur rent 40ns stc clock update interval. it will start counting at zero at the beginning of the 40ns period and every 8 ns it will be incremented. the information provided by the ptp_rtc_phase register will increase the accuracy of the various timestamps and s tc clock readings.
micrel, inc. ksz8463ml/rl/fml/frl june 11, 2014 5 0 revision 1.0 updating the system time clock the ksz8463 provides four mechanisms for updating the system time cl ock : ? directly set the time ? step time adjustment ? continuous time adjustment ? temporary time adjustment directly setting or reading the time directly setting the system time clock to a value is accomplished by setting a new time in the real time clock registers (ptp_rtc_sh/l, ptp_rtc_nsh/l and ptp_rtc_phase) and then setting the load ptp 1588 clock bit (ptp_load_clk). directly reading the system time clock is accomplished by setting the read ptp 1588 clock bit (ptp_read_clk). to avoid lower bits overflowing during reading the system time clock, a snapshot register technique is used. the value in the system time clock wi ll be saved into a snapshot register by setting the ptp_read_clk bit in ptp_clk_ctl, and then subsequent reads from ptp_rtc_s, ptp_rtc_ns, and ptp_rtc_phase will return the system time clock value. the cpu will add the ptp_rtc_phase value to ptp_rtc_s and ptp_rtc _ns to get the exact real time. step - time adjustment the system time clock can be incremented in steps if desired. the nanosecond value (ptp_rtc_nsh/l) can be added or subtracted when the ptp_step_adj_clk bit is set. the value will be added to the s ystem time clock if this action occurs while the ptp_step_dir bit = ?1?. the value will be subtracted from the system time clock if this action occurs while the ptp_step_dir bit = ?0?. the ptp_step_adj_clk bit is self - clearing. continuous time adjustment t he system can be set up to perform continuous time adjustment to the 1588 ptp clock. this is the mode that is anticipated to be used the most. this mode is overseen by the local processor and provides a method of periodically adjusting the count of the ptp clock to match the time of the master clock as best as possible. the rate registers (ptp_sns_rate_h and ptp_sns_rate_l) (0x610 ? 0x613) are used to provide a value by which the sub - nanosecond port ion of the clock is adjusted on a periodic basis. while con tinuous adjustment mode ( ptp_continu_adj_clk = ?1?) is selected every 40ns the sub - nanosecond value of the clock will be adjusted in either a positive or negative direction as determined by the ptp_rate_dir bit. the value will be positively adjusted if ptp _rate_dir = ?0? or negatively adjusted if ptp_rate_dir = ?1?. the rate adjustment allows for correction with resolution of 2 - 32 ns for every 40ns reference clock cycle , and it will be added to or subtracted from the system time clock on every reference cloc k cycle right after the write to ptp_snc_rate_l is done. to stop the continuous time adjustment, one can either set the ptp_continu_adj_clk = ?0? or the ptp_sns_rate_h/l value to zero. temporary time adjustment this mode allows for the continuous time adju stment to take place over a specified period of time only. the period of time is specified in the ptp_adj_dura_h/l registers. this mode is enabled by setting the ptp_temp_adj_clk bit to one. once the duration is reached, the increment or decrement will cea se. when the temporary time adjustment is done, the internal duration counter register (ptp_adj_dura_h/l) will stay at zero, which will disable the time adjustment. the local processor needs to set the ptp_temp_adj_clk to one again to start another tempora ry time adjustment with the reloaded value into the internal rate and duration registers. the ptp_adj_dura_l register needs to be programmed before ptp_adj_dura_h register. the ptp_adj_dura_l, ptp_adj_dura_h and ptp_sns_rate_l registers need to be programm ed before the ptp_sns_rate_h register. the temporary time adjustment will start after the ptp_temp_adj_clk bit is set to one. this bit is self - cleared when the adjustment is completed. software can read this bit to check whether the adjustment is still in progress.
micrel, inc. ksz8463ml/rl/fml/frl june 11, 2014 51 revision 1.0 ptp clock initialization during software initialization when the device is powering up, the ptp clock needs to be initialized in preparation for synchronizing to the master clock . the suggested order of tasks is to reset the ptp 1588 clock (rese t_ptp_clk = ?0?), load the ptp 1588 clock (ptp_load_clk = ?1?) with a value then enable the ptp 1588 clock (en_ptp_clk = ?1?). during the initial synchronization attempt, the system time clock may be a little far apart from the ptp master clock, so it most likely will require a step - time adjustment to get it closer. after that, the continuous time adjustment method or temporary time adjustment method may be the best options when the system time clock is close to being synchronized with the master clock. mo re details on the 1588 ptp system time clock controls and functions can be found in the register descriptions for registers 0x600 to 0x617. ieee 1588 ptp message processing the ksz8463 sup port s ieee 1588 ptp time synchronization when 1588 ptp mode and message detection are enabled in the ptp_msg_cfg_1 register (0x620 ? 0x621). different operations will be applied to ptp packet processing based on the setting of p2p or e2e in transparent clock mo de for port 1 and port 2, master or slave in ordinary clock mode for port 3 (host port ), one - step or two - step clock mode, and if the domain checking is enabled. for the ipv4/udp egress packet, the checksum can be updated by either re - calculating the two - by tes or by setting it to zero. for the ipv6/udp egress packet, the checksum is always updated. all these 1588 ptp configuration bits are in the ptp_msg_cfg_1/2 registers (0x620 ? 0x623). for a more detailed description of the 1588 ptp message processing con trol and function, please refer to the register descriptions in the register map at locations 0x620 to 0x68f. ieee 1588 ptp ingress packet processing the ksz8463 can detect all ieee 802.3 ethernet 1588 ptp packets, ipv4/udp 1588 ptp packets, and ipv6/udp 1 588 ptp packets by enabling these features in the ptp_msg_cfg_1 register (0x620 ? 0x621). upon detection of receiving a 1588 ptp packet, the device will capture the receive timestamp at the time when the start - of - frame delimiter (sfd) is detected . adjustin g the receive timestamp with the receive latency or asymmetric delay is the responsibility of the software. the hardware only takes these values into consideration when it updates the correction field in the ptp message header. likewise, the software needs to adjust the transmit timestamp with the transmit latency . both the ingress timestamp and the ingress port number will be embedded in the reserved fields of the 1588 ptp header. the embedded information will be used by the host to designate the destinati on port in the response egress packet, identify the direction of the master port , and to calculate the link delay and offset. the 1588 ptp packet will be discarded if the 1588 ptp domain field does not match the domain number in the ptp_domain_ver registe r (0x624 ? 0x625) or if the 1588 ptp version number does not match version number (either 1 or 2) in the ptp_domain_ver register (0x624 ? 0x625). packets with a version number of one will always be forwarded to port 1 or port 2, and not to port 3. the 1588 ptp packets that are not associated with packet messages in pairs (pdelay_ req with pdelay_resp, sync with follow_up, delay_req with delay_resp) can be filtered and not forwarded to port 3 if the corresponding enable bits are set in the ptp_msg_cfg_2 regi ster (0x0622 ? 0x623). the 1588 ptp version - 1 packet will be forwarded without being modified. ieee 1588 ptp egress packet processing the ingress timestamp, the trans port type of the 1588 ptp packet, the packet type (tagged or untagged), and the type of co rrection field update on the egress side are in the frame header and are accessible for modification by the egress logic in local switch packet memory. the 1588 ptp packet will be put in the egress queue of highest priority. from the 1588 ptp frame header inside the switch packet memory, the egress logic will get the correction field update instruction. the residence time, link delay in the ptp_p1/2_link_dly registers (0x646 ? 0x647 and 0x666 ? 0x667) or turn - around time might be added to the correction fie ld depending upon the type of 1588 ptp egress packet. the 1588 ptp packet received from port 3 (host port ) has the destination port information to forward as well as the timestamp information that will be used for updating the correction field in one - step clock operation.
micrel, inc. ksz8463ml/rl/fml/frl june 11, 2014 52 revision 1.0 this embedded information (in the reserved fields of 1588 ptp frame header) will be zeroed out before the egress packet is sent out to conform to the 1588 ptp standard. for one - step operation, the original timestamp will be inserted into the s ync packet. the egress timestamp of the sync packet will be latched in the p1/2_sync_ts registers (0x64c ? 0x64f and 0x66c ? 0x66f), the egress timestamps of delay_req, pdelay_req an d pdelay_resp will be latched in the p1/2_xdly_req_ts (0x648 ? 0x64b and 0x668 ? 0x6b) and p1/2_pdly_resp_ts registers (0x650 ? 0x653 and 0x670 ? 0x673). these latched egress timestamps will generate an interrupt to the host cpu and set the interrupt statu s bits in the ptp_ts_is register (0x68c ? 0x68d) if the interrupt enable is set in the ptp_ts_ie register (0x68e ? 0x68f). these captured egress timestamps will be used by the 1588 ptp software for link delay measurement, offset adjustment, and time calcu lation. the transmit delay value from the port 1 or port 2 timestamp reference point to the network connection point in the ptp_p1/2_tx_latency registers (0x640 ? 0x643) will be added to these value in the p1/2_sync_ts, p1/2_xdly_req_ts and p1/2_pdly_resp_ ts registers to get the egress timestamp with reference point to the network connection point. for transmit delay_req or pdelay_req packets, the value in the ptp_p1/2_asym_cor registers (0x644 ? 0x645 and 0x664 ? 0x665) will be subtracted from the correcti on field. ieee 1588 ptp event triggering and timestamping an event trigger output signal can be generated when the target and activation time matches the ieee1588 ptp system clock time. likewise, an event timestamp input can be captured from an external event input signal and the corresponding time on the ieee1588 ptp system clock will be captured. up to 12 gpio pins can be configured as either output signal when trigger target time is matching ieee 1588 ptp system clock time or monitoring input signal fo r external event timestamp. all event trigger outputs are generated by comparing the system clock time with trigger target time continuously to make sure time synchronization is always on - going. ieee 1588 ptp trigger output the ksz8463 sup port s up to 12 ev ent trigg er unit s w hich can output to any one of the 12 gpio pins by setting bits[3:0] in trig[1:12]_cfg_1 registers. multiple trigger unit s can be as signed to a single gpio pin at the same time as logical or?ed function allowing generation of more complex waveforms. also multiple trig ger unit s can be cascaded (one unit only at any time) to drive a single gpio pin to generate a long and repeatable bit sequence. each trigg er unit that is cascaded can be any signal type (edge, pulse, periodic, register - bits, and clock output). each trigger unit can be programmed to generate one time rising or falling edge (toggle mode), a single positive or negative pulse of programmable width, a periodic signal of programmable width, cycle time, bit - patterns to shift out from trig[1:12]_cfg_[1:8] registers, and each trigger unit can be programmed to generate interrupt of trigger output unit done and status in ptp_trig_ie/is registers. for each tri gger unit , the host cpu programs the desired output waveform, gpio pins, target time in trig[1:12]_tgt_ns and trig[1:12]_tgt_s registers that the activity is to occur, and enable the trigger output unit in trig_en register, then the trigger output signal w ill be generated on the gpio pin when the internal ieee 1588 ptp system time matches the desired target time. the device can be programmed to generate a pulse - per - second (pps) output signal. the maximum trigger output signal frequency is up to 12.5mhz. for a more detailed description of the 1588 ptp event trigger output control, configuration and function, please refer to the registers description in the register map from 0x200 to 0x397 locations. ieee 1588 ptp event timestamp input external event input s on the gpio pins can be monitored and timestamped with the resolution of 8ns. the external signal event can be monitored and detected as either rising edge, falling edge, positive pulse, or negative pulse by setting bits[7:6] in ts[1:12]_cfg registers. multi ple timestamp units can be cascaded or chained together to associate with a single gpio pin to detect a series of events. when event is detected, the timestamp will be captured in three fields: 32 - bit second field in ts[1:12]_smpl1/2_sh/l registers, 30 - bit nanosecond field in ts[1:12]_smpl1/2_nsh/l registers, and 3 - bit phase field in ts[1:12]_smpl1/2_sub_ns registers. second and nanosecond fields are updated every 25mhz clock cycle. the 3 - bit phase field is updated every 125mhz clock cycle and indica tes one of the five 8ns /125mhz clock cycles. the bit [14] in ts[1:12]_smpl1/2_nsh registers indicates the event timestamp input is either falling edge or rising edge.

micrel, inc. ksz8463ml/rl/fml/frl june 11, 2014 71 revision 1.0 global soft power - down mode soft power - down mode is entered by setting bits[1:0] = ?10? in pmctrl register. when the device is in this mode, all pll clocks are disabled, the phys and the macs are off, all internal registers value will change to default value, and the cpu serial interface is only used to wake - up this device from the current soft power - down mode to normal operation mode by setting bits[1:0] = ?00? in the pmctrl register. all strap - in pins are sampled to latch a ny new values when soft power - down is disabled. energy - efficient ethernet (eee) energy - e fficient ethernet (eee) is implemented in the ksz8463ml device as described in the ieee 802.3az specification for mii operations on port 1 and port 2. th e eee function is not available for fiber m ode port s using the ksz8463fml and ksz8463frl devices. eee is not performed at port 3 since that is a mac to mac interface and not a mac to phy interface. the internal connection between the mac and phy blocks are performed in m ii mode. the details of the implementation are provided in the information that follows. the standards are defined around a mac that sup port s special signaling associated with eee. eee saves power by keeping the voltage on the ethernet cable at approximate ly 0v for as often as possible during periods of no traffic activity. this is called low - power idle (lpi) state . however, the link will respond automatically when traffic resumes and do so in such a way as to not cause blocking or dr opping of any packets (the wake - up time for 100bt is specified to be less than 30s.) . the transmit and receive directions are independently controlled. note the eee is not specified or implemented for 10bt. in 10bt, the transmitter is already off during idle periods. the eee feature is enabled by default. eee is auto - negotiated independently for each direction on a link, and is enabled only if both nodes on a link support it. to disable eee, clear the next page enable bit(s) for the desired p ort (s) in the pcseeec regis ter (0x0f3) and restart auto - negotiation. based on the eee specification, the energy savings from eee occurs at the phy level. however, the ksz8463 device reduces the power consumption not only in the phy block but also in the mac and switch blocks by shut ting down any unused clocks as much as possible when the device is at lpi state. a comprehensive lpi request on/off policy is also built - in at the switch level to determine when to issue lpi requests and when to stop the lpi request. some software control options are provided in the device to terminate the lpi request in the early phase when certain events occur to reduce the latency impact during lpi recovery. a configurable lpi recovery time register is provided at each port t o specify the recovery time ( 25 s at default) required for the ksz8463 and its link partner before they are ready to transmit and receive a packet after going back to the normal state. for details, please refer to the ksz8463 eee registers (0x0e0 ? 0x0f7) description. the time during which lpi mode is active is during what is called quiet time. this is shown in figure 17 . figure 17 . traffic activity and eee
