6 / 9 page 6 21737-0400, Rev. O 2-7-2002 Transmitter Electrical Interface Receiver Electrical Interface Transmitter: When the DATA+ input is at logic HIGH and DATA- input is at logic LOW, the LD is ON; and vice versa. In single-ended applications, the unused input pin should be biased to V CC - 1.29 V. The transmitter is normally enabled (i.e. when the DISABLE control input is not connected). When the DISABLE control input voltage is higher than V CC - 2 V, the laser is disabled (less than -30dBm output power) independent of the input data. Receiver: Both differential DATA+ and DATA- outputs are PECL/ECL levels requiring termination (50 ohms to V CC - 2 volts or 510 ohms to VEE is recommended). For optimum performance, both outputs should be terminated in the same manner, even if only one is used. STX / SRX Application Notes Pin Assignments (Top View) The Signal Detect circuit monitors the level of the incoming optical signal and generates a logic LOW signal when insufficient photocurrent is produced. The SIGNAL DETECT outputs are PECL/ECL level requiring termination (510 ohms to V EE is recommended). If TTL interfaces for SIGNAL DETECT outputs are required, the SRX-12-L receivers can be used. Laser Safety: All transmitters are Class I Laser products per FDA/CDRH and IEC-825 standards. They must be operated under specified operating conditions. 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 CASE BIAS MONITOR + N/C V V TRANSMIT DISABLE N/C EE CC BIAS MONITOR - V V CC CC CASE FACET MONITOR + FACET DATA+ DATA - N/C V MONITOR - V CASE V CC EE CC Transmitter 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 CASE N/C N/C N/C N/C V DATA+ EE V DATA - V EE PD CASE N/C N/C N/C N/C SIGNAL DETECT - CASE SIGNAL DETECT+ VCC VEE Receiver N/C: No internal connection Parameter Symbol Minimum Typical Maximum Units Supply Voltage 1 VCC - VEE 4.75 5.0 5.5 V Supply Current receptacled-DFB I -90 150 mA all others - 70 130 Input HIGH Voltage VIH VCC - 1.165 - VCC - 0.880 V Input LOW Voltage VIL VCC - 1.810 - VCC - 1.475 V Transmitter Disable Voltage VDIS VCC - 2.0 - VCC V Transmitter Enable Voltage VEN VEE - VEE + 0.8 V Differential Bias Monitor Voltage at 25°C VBM,DIF - 80 120 mV at 85°C - 280 500 Differential Back Facet Monitor Voltage VFM,DIF 20 100 200 mV 1 For - 5V single supply, connect V CC to 0V (circuit ground) and VEE to - 5V.

For +5V single supply : VCC = +5V and VEE = VPD = CASE = 0V (circuit ground). For - 5V single supply : VCC = CASE = 0V (circuit ground) and VEE = VPD = - 5V. CASE is always connected to circuit ground. Optical Communication Products, Inc.
