Differential Data Input. 75K pull-down on D, 75k pull-up and 75k pull-down on /D.
TTL Input with 75k pull-up: Default HIGH for normal operation; LOW to disable modulation
current.
TTL Input with 75k pull-up: Default HIGH for latched (clocked) data; LOW for direct data.
Connect this pin to a monitor photodiode anode, a resistor (R
This sets the desired average optical power.
