fiber optics V23818-K305-V15, sff, mm 850nm 1.0625 gbd fiber channel, 1.3 gbe 2x5 trx (vf-45) 2 description the infineon gigabit ethernet multimode transceiverpart of infineon small form factor transceiver familyis based on the physical medium depend (pmd) sublayer and baseband medium, type 1000base-sx (short wavelength). the appropriate fiber optic cable is 62.5 m or 50 m multi- mode fiber with vf-45? (volition?) connector. operating range for 1000base-sx over each optical fiber type the infineon gigabit ethernet multimode transceiver is a single unit comprised of a transmitter, a receiver, and an vf-45? receptacle. this design frees the customer from many align- ment and pc board layout concerns. this transceiver supports the innovative volition connectoriza- tion concept, which competes with utp/cat 5 solutions. it is compatible with rj-45 style backpanels for fiber-to-the-desktop applications while providing the advantages of fiber optic tech- nology. the receptacle accepts the new sg/vf-45? connector. the small form factor is specially developed for distances of up to 550 m. the module is designed for low cost lan, wan, and gigabit ethernet 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, hubs, and local and wide area switches. this transceiver operates at 1.25 gbits per second from a single power supply (+3.3 v). the full differential data inputs and out- puts are pecl compatible. functional description of 2x5 pin row transceiver this transceiver is designed to transmit serial data via multimode 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 pecl compatible electrical serial data (td and tdnot) into optical serial data. data lines are differen- tially 100 w terminated. 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 makes an internal reset signal when- ever 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. technical data the electro-optical characteristics described in the following tables are valid only for use under the recommended operating conditions. recommended operating conditions notes 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. add max. 45 ma for the three outputs. load is 50 w to v cc C2 v. 2. data inputs are ac coupled with 100 w differential termination built into the transceiver. fiber type minimum range (meters) 62.5 micron mff 2 to 260 50.0 micron mff 2 to 550 10 micron sff not supported laser driver power control receiver o/e o/e laser e/o rx coupling unit tdC td+ rdC rd+ sd laser coupling unit multimode fiber len monitor automatic shut-down parameter symbol min. typ. max. units case temperature t c 070 c power supply voltage v cc Cv ee 3.1 3.3 3.5 v transmitter input voltage swing |v td+ Cv td C| 300 900 mv data input low voltage (2) v il Cv cc C900 C300 input data rise/fall time, 10%C90% t r , t f 100 375 ps receiver input center wavelength l c 770 860 nm
