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.
