G Datacomms Modules

DESCRIPTION

The CX02066 is a highly integrated, programmable

laser driver intended for SONET/SDH applications with

FEC to 3 Gbps. Using differential PECL data and

clock inputs, the CX02066 supplies the bias and

modulation current for driving an edge-emitting laser.

The modulation output can be DC-coupled to the laser

diode, giving a significant power saving over

AC-coupled operation.

The CX02066 includes automatic power control to

maintain a constant average laser output power over

temperature and life. In addition, the modulation

current is temperature compensated to minimize

variation in extinction ratio over temperature.

Output flags indicate laser end of life as well as failure

of the APC circuitry to maintain average output power.
