v23826-k305-cxx/cxxx description data sheet 3 2004-10-29 description the infineon fibre channel / gigabit ethernet multimode transceiver ? part of infineon 1x9 family ? is based on the physical medium depend (pmd) sublayer and baseband medium, type 1000 base-sx (short wavelength) as specified in ieee std 802.3 and fibre channel fc-pi (rev. 13) 100-m5-sn-i, fc-pi (rev. 13) 100-m6-sn-i. the appropriate fiber optic cable is 62.5 m or 50 m multimode fiber with duplex sc connector. the infineon multimode 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 ethernet, and fibre channel applications. it can be used as the network 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 v or 3.3 v). the full differential data inputs and outputs are pecl compatible. link length as defined by ieee and fibre channel standards fiber type reach unit min. 1) 1) minimum reach as defined by ieee and fibre channel standards. a 0 m link length (loop-back connector) is supported. max. 2) 2) maximum reach as defined by ieee and fibre channel standards. longer reach possible depending upon link implementation. at 1.0625 gbit/s 50 m, 2000 mhz*km 2 860 meters 50 m, 500 mhz*km 2 500 50 m, 400 mhz*km 2 450 62.5 m, 200 mhz*km 2 300 62.5 m, 160 mhz*km 2 250 at 1.3 gbit/s 50 m, 500 mhz*km 2 550 meters 50 m, 400 mhz*km 2 500 62.5 m, 200 mhz*km 2 275 62.5 m, 160 mhz*km 2 220
v23826-k305-cxx/cxxx description data sheet 4 2004-10-29 functional description this transceiver is designed to transmit serial data via multimode cable. figure 2 functional diagram the receiver component converts the optical serial data into pecl compatible electrical data (rd+ and rd?). the signal detect (sd, active high) shows whether an optical signal is present. the transmitter converts electrical pecl compatible serial data (td+ and td?) 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. laser driver laser monitor power control receiver sd td+ rd+ rd ? td ? laser coupling unit rx coupling unit e/o o/e o/e len file: 1363 automatic shut-down multimode fiber
v23826-k305-cxx/cxxx description data sheet 5 2004-10-29 the transmitter contains a laser driver circui t 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. 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. regulatory compliance feature standard comments esd: electrostatic discharge to the electrical pins mil-std 883d method 3015.7 jesd22-a114-b class 1 (> 1000 v) hbm class 1c immunity: electrostatic discharge (esd) to the duplex sc receptacle en 61000-4-2 iec 61000-4-2 discharges of 15 kv with an air discharge probe on the receptacle cause no damage. immunity: radio frequency electromagnetic field en 61000-4-3 iec 61000-4-3 with a field strength of 3 v/m, noise frequency ranges from 10 mhz to 1 ghz. no effect on transceiver performance between the specification limits. emission: electromagnetic interference (emi) fcc 47 cfr part 15 class b en 55022 class b cispr 22 noise frequency range: 30 mhz to 18 ghz; margins depend on pcb layout and chassis design.

v23826-k305-cxx/cxxx application notes data sheet 10 2004-10-29 application notes 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).
