v23826-c18-t63 v23826-c18-t363 description data sheet 4 2000-01-01 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) . the transmitter converts electrical pecl compatible serial data (td and tdnot) into optical serial data. this version contains an input signal monitor (i sm), that switches the optical power off if a continuously low level is applied at data input. the transmitter contains a laser driver circuit that drives the modulation and bias current of the laser diode. the currents are control led 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 15 milliseconds after the voltage has risen above the reset threshold. during this time the laser is inactive. 1) we recommend to switch off the transmitter supply ( v cc - tx) if no transmitter input data is applied. regulatory compliance feature standard comments electrostatic discharge (esd) to the electrical pins mil-std 883c method 3015.4 class 1 (>1000 v) 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 10 v/m rms, noise frequency ranges from 10 mhz to 1 ghz. no effect on transceiver performance between the specification limits. emission: electromagnetic interference emi fcc class b en 55022 class b cispr 22 noise frequency range: 30 mhz to 6 ghz; margins depend on pcb layout and chassis design

v23826-c18-t63 v23826-c18-t363 application notes data sheet 10 2000-01-01 this application note assumes fiber optic transceivers using 5 v power supply and serdes chips using 3.3 v power supply. it also assumes no 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 connected to serdes-chips using standard pecl termination network. value of r1...r4 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. further application notes for electrical interfacing are available upon request. ask for appnote 82. we strongly recommend a v ee plane under the module for getting good emi performance. the transceiver contains an automatic shutdown circuit. reset is only possible if the power is turned off, and then on again. ( v cc tx switched below v th ). application board available on request.
