CCO
Most positive power supply pins separation helps
to isolate sensitive circuitry from noise
generating function. +5V for PECL operation
or ground for ECL operation.
V
EE
Most negative power supply input. Ground
for PECL operation or -5V for ECL operation.
V
BB
This pin provides a reference voltage for use
in single ended applications or when the
input signal is AC coupled into the device.
D,D
These differential ECL/PECL 100K
compatible inputs receive NRZ data.
CLK, CLK
These differential clock inputs
MR
This ECL/PECL 100K compatible input resets
the Laser Driver Logic - modulation current
transitions to zero when asserted high.
OUT, OUT
Open collector outputs from the modulation
buffer drive these differential current outputs.
MC
An external voltage sets the main value of
modulation current I
O

R
SET
An external resistor sets the source current
for modulation I
