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.
