PRODUCT DESCRIPTION
The ANADIGICS AMT8410, packaged in a TO46
lens can, is a 3.3 V integrated photodetector and
transimpedance amplifier (TIA) used to convert a
long wavelength (1270 to 1560 nm) input optical
signal into a differential output voltage. The
AMT8410 has a bandwidth of 2000 MHz and a
dynamic range of 25 dB. These devices are readily
designed into receivers, transceivers and
transponders for SONET, Fibre Channel and
Infiniband applications.
