Pin Descriptions Pin Number Pin Name Function 1 ENA Bias and modulation output enable (TTL/CMOS). Logic HIGH for normal operation. 2 DIS Bias and modulation output disable (TTL/CMOS). Logic LOW for normal operation. 3BIASMON Bias monitor. Connect a resistor between this pin and VCC to monitor bias current. Connect to VCC if not used. 4MODMON Modulation monitor. Connect a resistor between this pin and VCC to monitor modulation current. Connect to VCC if not used. 5FAIL Mean power control failure indicator (TTL/CMOS). Goes LOW when control loop is no longer able to maintain constant current at PD. 6OCA Over-current alarm (TTL/CMOS). Goes LOW when IBIAS exceeds the preset bias current limit. 7 GND Ground. 8 BIAS Laser bias current output. 9VCC Power supply. 10 OUT+ Positive modulation current output. Sinks current when DIN is HIGH. 11 OUT- Negative modulation current output. Sinks current when DIN is HIGH. 12 GNDA Ground to output stage. 13 PD Monitor photodiode input. This input is connected to the monitor photodiode anode for automatic power control. 14 CMPC Mean power control dominant pole capacitor. Connect to VCC via a capacitor. 15 GND Ground. 16 TCSLOPE Connecting a resistor between this pin and ground sets the temperature coefficient of IMODSET. 17 TCSTART Secondary temperature coefficient of IMOD. A resistor on this pin to ground sets the threshold temperature at which compensation starts. 18 MODSET Modulation current set. Connect a resistor between this pin and ground to set. 19 OCASET Over-current alarm set. Connect a resistor between this pin and ground to set. 20 VCC Power supply. 21 DIN Positive data input (PECL). Self biased. |
