General Description
The GD16076A is a 2.5 Gbit/s laser
modulator driver designed for providing a
controllable drive current to an optical
modulator (LiNbO
3
) circuit properly bi-
ased and with 25
or 50
characteris-
tic input impedance.
The GD16076A features differential ECL
compatible, wide common mode range
inputs (DIN, NDIN) with loop through ter-
mination capability for optimal input re-
flection coefficient.
The pins OUT and NOUT are open drain
outputs designed for driving an external
load with a characteristic impedance of:
u
25
(GD16076A-25SLP)
u
50
(GD16076A-50SLP)
The outputs can sink a current that can
be controlled in the range 40mA - 180mA
by VCIP. The output voltage swing
across an external load may be varied
accordingly.
For the 25
version the output voltage
swing may be adjusted in the range
1.0 V
P-P
- 4.5 V
P-P
.
For the 50
version, the output swing
may be adjusted within the range
2.0 V
P-P
- 6.0 V
P-P
(typ.).
The output current may be monitored at
pin SIP.
The part is housed in a high speed 40 pin
leaded Multi Layer Ceramic (MLC)
package.
