CX02068
3.3 Volt Laser Driver IC for 155/622 Mbps
The CX02068 is a highly integrated, programmable laser driver intended for Telecom applications up to 622 Mbps. Using differential PECL data, the CX02068 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 ACcoupled operation.
The CX02068 includes automatic power control (APC) to maintain a constant average laser output power over temperature and life.
