Single Chip Ethernet Controller with General Processor Interface 9. Functional Description
9.1 Host Interface The host interface is the ISA BUS compatible mode. There are eight IO bases, which are 300H, 310H, 320H, 330H, 340H, 350H, 360H, and 370H. The IO base is latched from strap pins or loaded from the EEPROM. There are only two addressing ports through the access of the host interface. One port is the INDEX port and the other is the DATA port. The INDEX port is decoded by the pin CMD =0 and the DATA port by the pin CMD =1. The contents of the INDEX port are the register address of the DATA port. Before the access of any register, the address of the register must be saved in the INDEX port. IMR is set, the memory address increment will wrap to location 0x0C00 if the end of address (i.e. 16K) is reached.
9.3 Packet Transmission There are two packets, sequentially named as index I and index II, can be stored in the TX SRAM at the same time. The index register 02h controls the insertion of CRC and pads. Their statuses are recorded at index registers 03h and 04h respectively. The start address of transmission is 00h and the current packet is index I after software or hardware reset. Firstly write data to the TX SRAM using the DMA port and then write the byte count to byte_ count register at index register 0fch and 0fdh. Set the bit 1 of control register. The DM9010 starts to transmit the index I packet. Before the transmission of the index I packet ends, the data of the next (index II) packet can be moved to TX SRAM. After the index I packet ends the transmission, write the byte count data of the index II to BYTE_COUNT register and then set the bit 1 of control register to transmit the index II packet. The following packets, named index I, II, I, II,..., use the same way to be transmitted. 9.4 Packet Reception The RX SRAM is a ring data structure. The start address of RX SRAM is 0C00h after software or hardware reset. Each packet has a 4-byte header followed with the data of the reception packet which CRC field is included. The format of the 4-byte header is 01h, status, BYTE_COUNT low, and BYTE_COUNT high. It is noted that the start address of each packet is in the proper address boundary which depends on the operation mode (the 8-bit, 16-bit or 32-bit mode).
9.2 Direct Memory Access Control The DM9010 provides DMA capability to simplify the access of the internal memory. After the programming of the starting address of the internal memory and then issuing a dummy read/write command to load the current data to internal data buffer, the desired location of the internal memory can be accessed by the read/write command registers. The memory's address will be increased with the size that equals to the current operation mode (i.e. the 8-bit, 16-bit or 32-bit mode) and the data of the next location will be loaded into internal data buffer automatically. It is noted that the data of the first access (the dummy read/write command) in a sequential burst should be ignored because that the data was the contents of the last read/write command. The internal memory size is 16K bytes. The first location of 3K bytes is used for the data buffer of the packet transmission. The other 13K bytes are used for the buffer of the receiving packets. So in the write memory operation, when the bit 7 of IMR is set, the memory address increment will wrap to location 0 if the end of address (i.e. 3K) is reached. In a similar way, in the read memory operation, when the bit 7 of

100Base-TX operation. 9.5 100Base-TX Operation The block diagram in figure 3 provides an overview of the functional blocks contained in the transmit section. The transmitter section contains the following functional blocks: - 4B5B Encoder - Scrambler - Parallel to Serial Converter - NRZ to NRZI Converter - NRZI to MLT-3 - MLT-3 Driver 9.5.1 4B5B Encoder The 4B5B encoder converts 4-bit (4B) nibble data generated by the MAC Reconciliation Layer into a 5-bit (5B) code group for transmission, see reference Table 1. This conversion is required for control and packet data to be combined in code groups. The 4B5B encoder substitutes the first 8 bits of the MAC preamble with a J/K code-group pair (11000 10001) upon transmit. The 4B5B encoder continues to replace subsequent 4B preamble and data nibbles with corresponding 5B code-groups. At the end of the transmit packet, upon the deassertion of the Transmit Enable signal from the MAC Reconciliation layer, the 4B5B encoder injects the T/R code-group pair (01101 00111) indicating the end of frame. After the T/R code-group pair, the 4B5B encoder continuously injects IDLEs into the transmit data stream until Transmit Enable is asserted and the next transmit packet is detected. The DM9010 includes a Bypass 4B5B conversion option within the 100Base-TX Transmitter for support of applications like 100 Mbps repeaters which do not require 4B5B conversion. 9.5.2 Scrambler The scrambler is required to control the radiated emissions (EMI) by spreading the transmit energy across the frequency spectrum at the media connector and on the twisted pair cable in By scrambling the data, the total energy presented to the cable is randomly distributed over a wide frequency range. Without the scrambler, energy levels on the cable could peak beyond FCC limitations at frequencies related to the repeated 5B sequences, like the continuous transmission of IDLE symbols. The scrambler output is combined with the NRZ 5B data from the code-group encoder via an XOR logic function. The result is a scrambled data stream with sufficient randomization to decrease radiated emissions at critical frequencies. 9.5.3 Parallel to Serial Converter The Parallel to Serial Converter receives parallel 5B scrambled data from the scrambler, and serializes it (converts it from a parallel to a serial data stream). The serialized data stream is then presented to the NRZ to NRZI encoder block 9.5.4 NRZ to NRZI Encoder After the transmit data stream has been scrambled and serialized, the data must be NRZI encoded for compatibility with the TP-PMD standard, for 100Base -TX transmission over Category-5 unshielded twisted pair cable. 9.5.5 MLT-3 Converter The MLT-3 conversion is accomplished by converting the data stream output, from the NRZI encoder into two binary data streams, with alternately phased logic one event. 9.5.6 MLT-3 Driver The two binary data streams created at the MLT-3 converter are fed to the twisted pair output driver, which converts these streams to current sources and alternately drives either side of the transmit transformer's primary winding, resulting in a minimal current MLT-3 signal. Refer to figure 4 for the block diagram of the MLT-3 converter.

9.6 100Base-TX Receiver The 100Base-TX receiver contains several function blocks that convert the scrambled 125Mb/s serial data to synchronous 4-bit nibble data that is then provided to the MII. The receive section contains the following functional blocks: - Signal Detect - Digital Adaptive Equalization - MLT-3 to Binary Decoder - Clock Recovery Module - NRZI to NRZ Decoder - Serial to Parallel - Descrambler - Code Group Alignment - 4B5B Decoder 9.6.1 Signal Detect The signal detects function meets the specifications mandated by the ANSI XT12 TP-PMD 100Base-TX standards for both voltage thresholds and timing parameters. 9.6.2 Adaptive Equalization When transmitting data over copper twisted pair cable at high speed, attenuation based on frequency becomes a concern. In high speed twisted pair signaling, the frequency content of the transmitted signal can vary greatly during normal operation based on the randomness of the scrambled data stream. This variation in signal attenuation, caused by frequency variations, must be compensated for to ensure the integrity of the received data. In order to ensure quality transmission when employing MLT-3 encoding, the compensation must be able to adapt to various cable lengths and cable types depending on the installed environment. The selection of long cable lengths for a given implementation requires significant compensation, which will be over-killed in a situation that includes shorter, less attenuating cable lengths. Conversely, the selection of short or intermediate cable lengths requiring less compensation will cause serious under-compensation for longer length cables. Therefore, the compensation or equalization must be adaptive to ensure proper conditioning of the received signal independent of the cable length. 9.6.3 MLT-3 to NRZI Decoder The DM9010 decodes the MLT-3 information from the Digital Adaptive Equalizer into NRZI data. The relationship between NRZI and MLT-3 data is shown in figure 4. 9.6.4 Clock Recovery Module The Clock Recovery Module accepts NRZI data from the MLT-3 to NRZI decoder. The Clock Recovery Module locks onto the data stream and extracts the 125 MHz reference clock. The extracted and synchronized clock and data are presented to the NRZI to NRZ decoder. 9.6.5 NRZI to NRZ The transmit data stream is required to be NRZI encoded for compatibility with the TP-PMD standard for 100Base-TX transmission over Category-5 unshielded twisted pair cable. This conversion process must be reversed on the receive end. The NRZI to NRZ decoder, receives the NRZI data stream from the Clock Recovery Module and converts it to a NRZ data stream to be presented to the Serial to Parallel conversion block. 9.6.6 Serial to Parallel
The Serial to Parallel Converter receives a serial data stream from the NRZI to NRZ converter. It converts the data stream to parallel data to be presented to the descrambler.
9.6.7 Descrambler Because of the scrambling process requires to control the radiated emissions of transmit data streams, the receiver must descramble the receive data streams. The descrambler receives scrambled parallel data streams from the Serial to Parallel converter, and it descrambles the data streams, and presents the data streams to the Code Group alignment block.

9.6.8 Code Group Alignment The Code Group Alignment block receives un-aligned 5B data from the descrambler and converts it into 5B code group data. Code Group Alignment occurs after the J/K is detected and subsequent data is aligned on a fixed boundary. 9.6.9 4B5B Decoder The 4B5B Decoder functions as a look-up table that translates incoming 5B code groups into 4B (Nibble) data. When receiving a frame, the first 2 5-bit code groups receive the start-of-frame delimiter (J/K symbols). The J/K symbol pair is stripped and two nibbles of preamble pattern are substituted. The last two code groups are the end-of-frame delimiter (T/R Symbols). The T/R symbol pair is also stripped from the nibble, presented to the Reconciliation layer. 9.7 10Base-T Operation The 10Base-T transceiver is IEEE 802.3u compliant. When the DM9010 is operating in 10Base-T mode, the coding scheme is Manchester. Data processed for transmit is presented to the MII interface in nibble format, converted to a serial bit stream, then the Manchester encoded. When receiving, the bit stream, encoded by the Manchester, is decoded and converted into nibble format to present to the MII interface. 9.8 Collision Detection For half-duplex operation, a collision is detected when the transmit and receive channels are active simultaneously. When a collision is detected, it will be reported by the COL signal on the MII interface. Collision detection is disabled in Full Duplex operation. 9.10 Auto-Negotiation The objective of Auto-negotiation is to provide a means to exchange information between linked devices and to automatically configure both devices to take maximum advantage of their abilities. It is important to note that Auto-negotiation does not test the characteristics of the linked segment. The Auto-Negotiation function provides a means for a device to advertise supported modes of operation to a remote link partner, acknowledge the receipt and understanding of common modes of operation, and to reject un-shared modes of operation. This allows devices on both ends of a segment to establish a link at the best common mode of operation. If more than one common mode exists between the two devices, a mechanism is provided to allow the devices to resolve to a single mode of operation using a predetermined priority resolution function. Auto-negotiation also provides a parallel detection function for devices that do not support the Auto-negotiation feature. During Parallel detection there is no exchange of information of configuration. Instead, the receive signal is examined. If it is discovered that the signal matches a technology, which the receiving device supports, a connection will be automatically established using that technology. This allows devices not to support Auto-negotiation but support a common mode of operation to establish a link. 9.9 Carrier Sense Carrier Sense (CRS) is asserted in half-duplex operation during transmission or reception of data. During full-duplex mode, CRS is asserted only during receive operations.

9.11 Power Reduced Mode The Signal detect circuit is always turned to monitor whether there is any signal on the media (cable disconnected). The DM9010 automatically turns off the power and enters the Power Reduced mode, whether its operation mode is N-way or force mode. When enters the Power Reduced mode, the transmit circuit still sends out fast link pules with minimum power consumption. If a valid signal is detected from the media, which might be N-ways fast link pules, 10Base-T normal link pules, or 100Base-TX MLT3 signals, the device will wake up and resume a normal operation mode. That can be writing Zero to PHY Reg.16.4 to disable Power Reduced mode. 9.11.1 Power Down Mode The PHY Reg.0.11 can be set high to enter the Power Down mode, which disables all transmit, receive functions and MII interface functions, except the MDC/MDIO management interface. 9.11.2 Reduced Transmit Power Mode The additional Transmit power reduction can be gained by designing with 1.25:1 turns ration magnetic on its TX side and using a 8.5K resistor on BGRES and AGND pins, and the TXO+/TXO- pulled high resistors should be changed from 50 to 78 . This configuration could be reduced about 20% transmit power.

11.1 Network Interface Signal Routing Place the transformer as close as possible to the RJ-45 connector. Place all the 50 resistors as close as possible to the DM9010 RXI and TXO pins. Traces routed from RXI and TXO to the transformer should run in close pairs directly to the transformer. The designer should be careful not to cross the transmit and receive pairs. As always, vias should be avoided as much as possible. The network interface should be void of any signals other than the TXO and RXI pairs between the RJ-45 to the transformer and the transformer to the DM9010.. There should be no power or ground planes in the area under the network side 11.2 10Base-T/100Base-TX HP Auto-MDIX Application
of the transformer to include the area under the RJ-45 connector. (Refer to Figure 11-4 and 11-5) Keep chassis ground away from all active signals. The RJ-45 connector and any unused pins should be tied to chassis ground through a resistor divider network and a 2KV bypass capacitor. The Band Gap resistor should be placed as physically close as pins 25 and 26 as possible (refer to Figure 11-1 and 11-2). The designer should not run any high-speed signal near the Band Gap resistor placement.
