Function
Separate positive power supply pins help
to isolate sensitive circuitry from noise
generating function. +5V for PECL operation
or ground for ECL operation.
Most negative power supply input. Ground
for PECL operation or -5V for ECL operation.
This pin provides a reference voltage for use
in single ended applications or when the
input signal is AC coupled into the device.
These differential ECL/PECL 100K
compatible inputs receive NRZ data.
This ECL/PECL 100K compatible input enables
Laser Driver - modulation current transitions to
zero when asserted HIGH.
Open collector outputs from the modulation
buffer drive these differential current outputs.
An external voltage sets the main value of
modulation current IO.
An external resistor sets the source current
for modulation Imod.
These pins are not connected.
