VSC7975, VSC7977
1/2/4 Gbps Multirate Transimpedance Amplifier
GENERAL DESCRIPTION:
The VSC7975 and VSC7977 are multirate
transimpedance amplifiers for Gigabit
Ethernet, Fibre Channel, and Infiniband
applications. The devices provide a means for
adjusting their bandwidth to allow full
compliance with multiple Gigabit Ethernet, Fibre Channel, and
Infiniband standards. The VSC7975 and VSC7977 are equipped
with a single pin that serves both as a control for bandwidth
as well as a linear received optical power monitor. This allows
the device to have multirate bandwidth control, power monitoring,
and differential outputs and be assembled in a standard 5-pin TO-
46 package. A space-saving filter connection is provided for
positive bias to the photodiode through a filter resistor to VCC.
The VSC7977 is available in die form or 5-pin TO-46 package with
short wavelength PIN photo detector. The VSC7975 is available in
a 5-pin TO-46 package with long wavelength PIN photo detector.
