CXB1548Q-Y
Description
The CXB1548Q-Y is a high-speed monolithic
Laser Driver/Current Switch with ECL input level.
Open collector outputs are provided at the output
pins (Q, Q) and have the capability of driving
modulation current of 60mApp at a max. data rate of
2.0Gbps (NRZ). DRIVADJ and SDRIV inputs control
the modulation current amplitude, and BIASADJ,
SBIAS inputs control the bias current. Modulation
and bias current can be controlled by either voltage
or current through these pins. This device includes
three Operational Amplifiers and Laser Shutdown
function.
