Power Supply for Digital Circuits
Noninverting PECL Input
Inverting PECL Input
Positive PECL Clock Input. Connect to V
Negative PECL Clock Input. Leave unconnected if latch function is not used.
TTL/CMOS Latch Input. High for latched data, low for direct data. Internal 100kΩ pull-up to V
TTL/CMOS Enable Input. High for normal operation, low to disable laser bias and modulation
current. Internal 100kΩ pull-up to V
Ground for Digital Circuits
Bias Current Monitor. Sink current source that is proportional to the laser bias current.
Modulation Current Monitor. Sink current source that is proportional to the laser modulation
current.
TTL/CMOS Failure Output. Indicates APC failure when low.
