fiber optics V23826-H18-C16/c56/c66/c76, sm 1300 nm 622 mbd atm 1x9 trx, ext. temp. 2 description the infineon (former siemens company) single mode atm transceiver complies with the atm forum's network compati- ble atm for local network applications document and ansi's broadband isdncustomer installation interfaces, physical media dependent specification , t1.646-1995, bellcore - sonet oc-3 / ir-1 and oc-12 / ir-1, itu-t g.957 stm-1 / s.1.1 and stm-4 / s.4.1. atm was developed to facilitate solutions in mul- timedia applications and real time transmission. the data rate is scalable, and the atm protocol is the basis of the broadband public networks being standardized in the international tele- communications 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 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, as well as wide area atm switches. this transceiver operates at 622.080 mbits per second from a single power supply (+5 volt or 3.3 volt). the differential data inputs and outputs 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 (rd and rdnot). the signal detect (sd, active high) shows whether an optical signal is present. the transmitter converts electrical pecl compatible serial data (td and tdnot) into optical serial data. the following versions are available: 1. ac/dc transceiver tx is ac coupled with differential 100 w load. rx has standard pecl output and is dc coupled. 2. ac/ac ttl transceiver tx and rx are ac coupled. tx has differential 100 w load. signal detect is ttl compatible. 3. dc/dc transceiver standard pecl inputs and outputs tx and rx are dc coupled. this version contains an input signal monitor (ism), that switches off the optical power if a continuously low level is applied at data input. 4. ac/ac pecl transceiver tx and rx are ac coupled. tx has differential 100 w load. signal detect is pecl compatible. the transmitter 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 out- put 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 pre- vent the laser power from exceeding the operating limits. 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 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. technical data the electro-optical characteristics described in the following tables are only valid for use under the recommended operating conditions. recommended operating conditions note 1. f o r v cc Cv ee (min., max.) 50% duty cycle. the supply current does not include the load drive current of the receiver output. 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* *dc/dc version only parameter symbol min. typ. max. units ambient temperature t amb C 40 85 c power supply voltage 3.3 v v cc Cv ee 3.1 3.3 3.5 v 5 v 4.75 5 5.25 supply current (1) 3.3 v i cc 250 ma 5 v 300 transmitter data input high voltage dc/dc v ih Cv cc C1165 C880 mv data input low voltage dc/dc v il Cv cc C1810 C1475 data input differential voltage ac/dc, ac/ac ttl, ac/ac pecl v diff 250 1600 input data rise/fall time 10%C90% t r , t f 100 1300 ps receiver input center wavelength l c 1270 1355 nm
