Pin Descriptions Pin No BCC+24 Pin No TQFP32 Name Function -18 VCC Power supply. Connect to VCC, do not leave open. - 22 GNDA Ground to output stage.(inductor to ground to optimize output stage performance) -32 VCC Power supply. Connect to VCC, do not leave open. - 5, 6, 8, 27 NC Not connected -7 VCC Power supply. Connect to VCC, do not leave open. -25 VCC Power supply. Connect to VCC, do not leave open. 1 9 ENA Bias and modulation output enable (TTL/CMOS). HIGH for normal operation 2 10 DIS Bias and modulation output disable (TTL/CMOS). LOW for normal operation 311 BIASMON Bias monitor. Connect a resistor between this pin and VCC to monitor. Connect to VCCif not in use. 412 MODMON Modulation monitor. Connect a resistor between this pin and VCC to monitor. Connect to VCC if not in use. 513 FAIL Mean power control failure indicator (TTL/CMOS). Goes low when control loop is no longer able to maintain constant current at PD 614 OCA Over-Current Alarm (TTL/CMOS). Goes low when IBIAS exceeds the preset bias current limit 7 - GND Ground. Connect to VCC, do not leave open. 8 17 BIAS Laser bias current output 91 VCC Power supply. Connect to VCC, do not leave open. 10 19 OUT+ Positive modulation current output. Sinks current when DIN is HIGH. 11 20 OUT- Negative modulation current output. Sinks current when DIN is HIGH. 12 23 GNDA Ground to output stage.(inductor to ground to optimize output stage performance) 13 24 PD Monitor photodiode input. This input is connected to the monitor photodiode anode for automatic power control. 14 26 CMPC Mean power control dominant pole capacitor 15 15 GND Ground. Connect to VCC, do not leave open. 16 28 TCSLOPE Connecting a resistor between this pin and ground sets the temperature coefficient of IMODSET (using the internal IC temperature). |
