PRODUCT DESCRIPTION
The ANADIGICS ATA7609 is a –5.2 V high-speed
transimpedance amplifier (TIA) designed for
10 Gb/s optical receiver applications available in
bare die form and manufactured using an InGaP
based HBT process. The device is used in
conjunction with a photodetector to convert an
optical signal into a differential output voltage that
can be AC or DC coupled to a post amplifier. The
ATA7609 has an internal overload support circuit
and can accept optical inputs as high as +3 dBm.
With its low noise and high optical overload capability,
the device is well suited for 10 Gb/s Ethernet and
OC-192 Very Short-Reach (VSR), Short-Reach,
Intermediate-Reach and Long-Reach optical
receivers, transceivers and transponders. The
ATA7609 is identical to the ATA7603 but with the
output polarities reversed.
