Reach Laser Driver

CX02066

The CX02066 is a low-cost 3 Gbps laser driver designed for

short-reach SONET applications. The modulator is capable

of driving modulation currents up to 85 mA. The modulation

current is adjustable by an external resistor. The IC has an

internal temperature compensation circuit for compensating

the temperature characteristic of laser diode slope

efficiency adjusted with an external resistor. External bias

and modulation monitors are provided, as well as safety

alarm functions.
