V23806-A84-C51 single mode 622 mbd atm 2x9 transceiver w/clock recovery 2 semiconductor group this siemens single mode atm transceiver is a single unit com- prised of a transmitter, a receiver, a clock recovery module, and an sc receptacle. this design frees the customer from many alignment and pc board layout concerns. the module is designed for low cost wan applications. it can be used as the network end device interface in workstations, servers, and stor- age devices, and in a broad range of network devices such as bridges, routers, and intelligent hubs, and wide area atm switches. this transceiver operates at 622.080 mbits per second from a single power supply (+5 volt). the differential data inputs, data outputs, clock outputs and signal detect output are pecl compatible. functional description of 2x9 pin row transceiver this transceiver is designed to transmit serial data via single mode cable. functional diagram the receiver component converts the optical serial data into pecl compatible electrical data (rxd and rxdn). it provides also a recovered in-phase clock and clock not signal. the signal detect (sd, active high) shows whether an optical signal is present. if no optical input signal is present the receiver data out- puts are switched to static low level (rd=low, rdnot=high). the transmitter part converts electrical pecl compatible serial data (txd and txdn) into optical serial data. it contains a laser driver circuit that drives the modulation and bias current of the laser diode. the currents are controlled by a power control circuit to guarantee constant output power of the laser over tempera- ture and aging. the power control uses the output of the monitor pin diode (mechanically built into the laser coupling unit) as a controlling signal, to prevent the laser power from exceeding the operating limits. the laser can be switched off with a logical high signal on the transmitter disable pin (txdis). the pwrmon pin shows a voltage reflecting the optical power output. the bias current is monitored on the biasmon pins. both signals can be used to supervise the function of the module. the signal txalm (optional) indicates an increasing of the optical output power of more than 2db. aging control is possible using the bias monitor output (biasmon). the module has an inte- grated shutdown function that switches the laser off in the event of an internal failure. laser driver laser power control receiver sd pll clock txalm txd rxd rxdn biasmon biasmon+ txdn laser coupling unit rx coupling unit e/o o/e o/e txdis pwrmon 3k 3k 10 single mode fiber automatic shut-down technical data the electro-optical characteristics described in the follow- ing tables are valid only for use under the recommended operating conditions. recommended operating conditions note 1. for v && Cv (( (min., max.). 50% duty cycle. the supply current does not include the load drive current of the receiver output. add max. 75 ma for the five outputs. load is 50 w to v && C 2 v. transmitter electro-optical characteristics notes 1. transmitter meets ansi t1e1.2, sonet oc-12, and itu g.957 mask patterns. 2. laser power is shut down if power supply is below v 7+ and switched on if power supply is above v 7+ after t 5(6 . the supervi- sory circuit can be reset by switching txdis from high to low. parameter symbol min. typ. max. units case temperature t & 070 c power supply voltage v && Cv (( 4.75 5 5.25 v supply current (1) i && 230 300 ma transmitter data input high voltage v ,+ Cv && C1165 C880 mv data input low voltage v ,/ Cv && C1810 C1475 input data rise/fall time, 10%C90% t r , t f 0.4 1.3 ns txdis input high voltage v 7,+ 2v txdis input low voltage v 7,/ 0.8 txdis input high current v 7,+ 0.8 ma txdis input low current v 7,/ C1 txalm output high voltage v 72+ 3.2 v txalm output low voltage v 72/ 0.7 txalm output high current i 72+ C3 ma txalm output low current i 72/ 3 receiver output current i o 25 ma input center wavelength l c 1260 1360 nm transmitter symbol min. typ. max. units output power (average) p 2 C15.0 C11.0 C8.0 dbm center wavelength l c 1274 1356 nm spectral width, rms s l 2.5 output rise time, 20%C80% t 5 240 700 ps output fall time, 20%C80% t ) 240 700 extinction ratio (dynamic) er 8.2 db eye diagram (1) ed reset threshold for txv && v 7+ 4.25 4.38 4.5 v reset active time out (2) t 5(6 140 240 560 ms
