GND Ground
BIASMON
Bias monitor and temperature-dependent bias current limit. Connect a resistor
between this pin and VCC to monitor.
MODMON
Bias monitor and temperature-dependent bias current limit. Connect a resistor
between this pin and VCC to monitor.
FAIL
Mean Power Control Failure indicator (TTL/CMOS). Goes LOW when control loop is
no longer able to maintain constant current at IPIN.
OCA
Over-Current Alarm (TTL/CMOS). Goes LOW when IBIAS exceeds the preset bias
current limit
BIAS Laser bias current output
19
OUT+ Positive modulation current output. Sinks current when DIN is HIGH.
20
OUT- Negative modulation current output. Sinks current when DIN is HIGH.
