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. The VSC7966 device is

equipped with SFP-compliant fault indicators, redundant disable control,

Automatic Power Control, temperature sensor, various signal monitors,

and robust eye safety features. The VSC7966 device is available in a 5

mm x 5 mm 32-pin QFP-N plastic package.
