CXB1558Q-Y

32 pin QFP (Ceramic)

E94720-PK

Laser Driver

Description

The CXB1558Q-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

D-FF for duty cycle correction and Laser Shutdown

function.
