General Description
The GD90573A evaluation board is de-
signed for evaluation of the performance
of the advanced Laser Driver circuit
GD16573A, designed for driving telecom
lasers with a 25 W characteristic load im-
pedance.
The GD90573A evaluation board com-
prises:

SMA connectors
50 W matching transmission lines for
balanced ECL signal inputs
25 W transmission line for output to
laser
Regulator for the negative supply
voltage VEE, which is operated from
a single external negative supply
Potentiometers for all necessary ad-
justments of the regulation circuits
Regulation circuit for control of the
Laser Driver’s modulation current.
The GD90573A is a fully tested evalua-
tion board with all necessary components
for normal operation.
For normal operation only an external
power supply, input data, relevant load
(laser unit), and measuring equipment is
necessary.
All that is necessary for a full application
is to mount a laser unit and apply power.
Relevant adjustments can then be under-
taken to match the actual laser unit.
