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.
TTL/CMOS Enable Input. High for normal operation, low to disable laser bias and modulation
currents.
A capacitor from this pad to ground delays the turn-on time of laser bias and modulation
currents.
TTL/CMOS output. Indicates APC failure when low.
No Connection. Leave unconnected.
