155 Mbps to 1.25 Gbps Laser Driver and Post Amplifier
G E N E R A L D E S C R I P T I O N :
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.
