Inverting Burst-Enable Input with On-Chip Biasing
TTL/CMOS Enable Input. Low for normal operation. Pull high or leave unconnected to disable laser
bias and modulation currents.
Power-Supply Ground
TTL/CMOS Failure Output. Indicates APC failure when low.

Monitor Diode Input. Connect this pin to the anode of the monitor diode. Leave unconnected for open-
loop operation. Minimize capacitance on this pin.
Maximum Bias Current Set. A resistor connected from this pin to ground sets the maximum bias
current. The bias current cannot exceed this level. The APC loop controls the bias current up to the
level of the BIASMAX. For APC open-loop operation, this pin sets the laser bias current.
Modulation Current Set. A resistor connected from this pin to ground sets the desired modulation current.
Average Power Control Set. A resistor connected from this pin to ground sets the desired average
optical power. Connect a 50k resistor to ground for APC open-loop operation.
Exposed Pad. Ground. This pad must be soldered to ground.
