GENERAL DESCRIPTION
The VSC7966 device is a multirate 1.25 Gbps integrated laser driver and limiting amplifier for SONET/SDH, Fast Ethernet, and Gigabit Ethernet applications optimized to reduce module cost. The device is intended to drive distributed feedback (DFB) and Fabry Perot (FP) lasers. A standard SPI port is provided for programming integrated digital to analog converters for laser bias current, modulation current, average power, and the limiting amplifier loss of signal threshold.
