fiber optics V23826-C18-T64/t364, sm 155mbd atm/sdh/sonet longhaul 1x9 trx (dc/dc) st 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/lr-1 and itu-t g.957 stm-1/l.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. the infineon single mode atm long haul transceiver is a single unit comprised of a transmitter, a receiver, and an st recepta- cle. 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, intelli- gent hubs, and wide area atm switches. this transceiver operates at 155.520 mbit/s from a single power supply (+5 v or +3.3 volt). the differential data inputs and out- puts are pecl compatible. functional description this transceiver is designed to transmit serial data via single mode cable. functional diagram the transmitter converts electrical pecl compatible serial data (td and tdnot) 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 temperature 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. this transceiver contains an input signal monitor (ism), that switches the optical power off if a continuously low level is applied at data input. the receiver component converts the optical serial data into pecl compatible electrical data (rd and rdnot). the signal detect (sd, active high) shows whether optical data is present (1) . this module is a class 1 laser product, due to an integrated automatic shutdown circuit that disables the laser when it detects transmitter failures. single fault condition is ensured by means of an integrated automatic shutdown circuit that disables the laser when it detects transmitter failures. a reset is only possible by turning the power off, and then on again. the transceiver contains a supervisory circuit to monitor the power supply. this circuit makes an internal reset signal when- ever 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 power control receiver o/e o/e laser e/o rx coupling unit td td rd rd sd laser coupling unit single mode fiber len monitor signal monitor and automatic shut-down ism
