fiber optics V23806-A84-C6, single mode 155 mbd atm/sdh/sonet 2x9 trx w/rx monitor, 5 v 2 description the infineon single mode atm transceiver complies with the atm forum ? s network compatible atm for local network applications document and ansi ? s broadband isdn - customer installation interfaces, physical media dependent specification , t1.646-1995, bellcore-sonet oc-3/ir-1 and itu-t g.957 stm-1/s.1.1. atm was developed to facilitate solutions in multimedia appli- cations and real time transmission. the data rate is scalable, and the atm protocol is the basis of the broadband public net- works being standardized in the international telecommunica- tions union (itu), the former international telegraph and telephone consultative committee (ccitt). atm can also be used in local private applications. this infineon single mode atm transceiver is a single unit com- prised of a transmitter, a receiver, 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 storage devices, and in a broad range of network devices such as bridges, routers, and intelli- gent hubs, and wide area atm switches. this transceiver operates at 155.52 mbit/s from a single power supply (+5 v). the differential data inputs, data outputs and sig- nal detect output are pecl compatible. functional description 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). the signal detect (sd, active high) shows whether an optical signal is present (1) . this transceiver offers the advantage of an analog rx power monitor (rxpmon) that can prove and control link status, including transmission distances and security of the connec- tion. this output shows an analog voltage that is proportional to the light input within the range of -20 dbm to -30 dbm. 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 cir- cuit to guarantee constant output power of the laser over tem- perature 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 high signal on the trans- mitter disable pin (txdis). the txpmon pin shows a voltage reflecting the optical power output. the bias current is moni- tored on the biasmon pins. both signals can be used to super- vise the function of the module. aging control is possible using the bias monitor output (bias- mon). the module has an integrated shutdown function that switches the laser off in the event of an internal failure. the transceiver contains a supervisory circuit to control the power supply. this circuit generates an internal reset signal whenever the supply voltage drops below the reset threshold. it keeps the reset signal active for at least 15 milliseconds after the voltage has risen above the reset threshold. during this time the laser is inactive. note 1. we recommend to switch off the transmitter supply (v cc -tx) if no transmitter input data is applied. laser driver laser power control receiver sd rxpmon txd rxd rxdn biasmon - biasmon+ txdn laser coupling unit rx coupling unit e/o o/e o/e txdis txpmon 3k 3k 10 single mode fiber automatic shut-down
