PRODUCT DESCRIPTION

The ANADIGICS ATA7603 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

ATA7603 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.
