PRODUCT DESCRIPTION
The ANADIGICS AMT8310, packaged in a 4 pin
TO-46 lens can, is a 3.3 V integrated photodetector
and transimpedance amplifier (TIA) used to convert
a short wavelength (850 nm) input optical signal into
a differential output voltage. The AMT8310 has a
bandwidth of 1.8 GHz, a dynamic range of over
23 dB and a sensitivity of -23 dBm. These devices
are readily designed into receivers, transceivers
and transponders for SONET, Fibre Channel and
Infiniband applications.
