M02066

Preliminary Information Preliminary Information This document contains information on a new product. The parametric information, although not fully characterized, is the result of testing initial devices. M02066 3.3 Volt Laser Driver IC for Applications to 3 Gbps Data Sheet The M02066 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 M02066 supplies the bias and modulation current required to drive 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 M02066 includes automatic power control to maintain a constant average laser output power over temperature and life. In addition, the modulation current can be 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 a...
