fibre optics v23826-k305-c13/53/63/73, multimode 850nm 1.3 gigabit ethernet 1x9 trx 2 description the infineon multi mode transceiver is based on the physical medium depend (pmd) sublayer and baseband medium, type 1000base-sx (long wavelength laser) (ieee 802.3z) and com- plies with the fibre channel physical and signaling interface (fc-ph), ansi xsi tt fibre channel physical standard class 100-m5-sli, latest revision. the appropriate fiber optic cable is 62.5 m or 50 m multi- mode fiber with duplex sc connector. the infineon multi mode transceiver is a single unit comprised 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 lan, wan, gigabit ether- net, and fibre channel applications. it can be used as the net- work end device interface in mainframes, workstations, servers, and storage devices, and in a broad range of network devices such as bridges, routers, intelligent hubs, and local and wide area switches. this transceiver operates at 1.0625 gbit/s and 1.3 gbit/s from a single power supply (+5 volt or 3.3 volt). the full differential data inputs and outputs are pecl compatible. operating range each optical fiber type at 1.0625 gbd functional description this transceiver is designed to transmit serial data via multi- 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. differential 100 ? 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 ? load. signal detect is ttl compatible. 3. dc/dc transceiver standard pecl inputs and outputs tx and rx are dc coupled. 4. ac/ac pecl transceiver tx and rx are ac coupled. tx has differential 100 ? 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 prevent 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 140 milliseconds after the voltage has risen above the reset threshold. during this time the laser is inactive. fiber type minimum range (meters) typ. 62.5 micron mff 2 to 260 400 50.0 micron mff 2 to 550 700 laser driver power control receiver o/e o/e laser e/o rx coupling unit td td rd rd sd laser coupling unit multimode fiber len monitor automatic shut-down

fibre optics v23826-k305-c13/53/63/73, multimode 850 nm 1.3 gigabit ethernet 1x9 trx 5 application note gigabit transceivers and matching circuits are high frequency components and shall be terminated as recommended in the application notes for proper emi performance. electromagnetic emission may be caused by these components. to prevent emissions it is recommended that cutouts for the fiber connectors be designed as small as possible. it is strongly recommended that the tx plug and the rx plug be separated with a bar that divides the duplex sc opening. if shielded parts are employed, they should be in proper contact with the bezel (back plane). since the shield is galvanically isolated from signal ground it is strongly recommended to prevent any contact between shield and the circuitry i.e. even any ground connection on the pcb may be harmful to emi performance. in cases where emi performance becomes critical it has proven to be helpful when using sc-plugs with less metal parts inside (as infineon fibers). application note multimode 850nm gigabit ethernet/fibre channel 1x9 transceiver, dc/dc version this application note assumes fiber optic transceivers using 5 v power supply and serdes chips using 3.3 v power supply. it also assumes self biasing at the receiver data inputs (rd+/ rd ? ) of the serdes chip. refer to the manufacturer data sheet for other applications. 3.3 v-transceivers can be directly con- nected to serdes-chips using standard pecl termination network. value of r1 may vary as long as proper 50 ? termination to v ee or 100 ? differential is provided. the power supply filtering is required for good emi performance. use short tracks from the inductor l1/l2 to the module v cc rx/v cc tx. the transceiver contains an automatic shutdown circuit. reset is only possible if the power is turned off, and then on again.
