Data Retiming Enable Input, Active-High. Retiming disabled when floating or pulled low.
TTL/CMOS Enable Input. Low for normal operation. Float or pull high to disable laser bias and
modulation currents. Internal 100kΩ pullup to V
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.
A capacitor between APCFILT1 and APCFILT2 sets the dominant pole of the APC feedback
loop (C
See above.
TTL/CMOS Failure Output, Active-Low. Indicates APC failure when low.
A resistor connected from this pin to ground sets the desired average optical power. Connect a
100kΩ resistor to GND for open-loop operation.
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.
Ground. Solder this pad to ground.
