A resistor connected from this pin to ground sets the desired modulation current.
Laser Bias Current Output. Connect to the laser through an inductor.
Positive Modulation-Current Output. I

Negative Modulation-Current Output. Current flows into this pin when input data is low. Connect
to load equivalent to that on OUT+ to maintain differential output balance.

Monitor Diode Input. Connect this pin to the anode of the monitor diode. Leave floating for
open-loop operation.

APCFILT1
A capacitor between APCFILT1 and APCFILT2 sets the dominant pole of the APC feedback
loop (C
APCFILT
= 0.01μF). Ground APCFILT1 for open-loop operation.
See above.
TTL/CMOS Failure Output, Active-Low. Indicates APC failure when low.

APCSET
A resistor connected from this pin to ground sets the desired average optical power. Connect a
100k
resistor to GND for open-loop operation.
24
BIASMAX
A resistor connected from this pin to ground sets the maximum bias current. The APC function
can subtract current from this maximum value, but cannot add to it. For open-loop operation,
this pin sets the laser bias current.
