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.
