Product Description

The ANADIGICS AMT8412, packaged in a 4 or 5

pin TO-46 lens can, is a 3.3V integrated

photodetector

and

transimpedance

amplifier

(TIA) used to convert a long wavelength (1250 to

1620nm) optical input signal into a differential

output voltage. The AMT8412 has a typical

bandwidth of 1.9GHz and a dynamic range of

over 25dB. The 5 pin package allows separate

biasing and current monitoring of the photodiode.

These

devices

are

readily

designed

into

receivers, transceivers and transponders for

SONET OC-48 and SDH STM-16 applications.
