| AMT8650 10 Gb/s 1310/1550nm PIN-TIA ADVANCED PRODUCT INFORMATION - Rev 0.0 FEATURES * * * * * * 10 Gb/s differential output TIA 8.5 GHz Bandwidth -19 dBm Typical Sensitivity +3 dBm Optical Overload 1250-1620nm PIN Photodetector Transimpedance gain of 10K and 600mVpp output APPLICATIONS * * SONET OC-192/SDH STM-64 10Gb/s Ethernet High speed 5-pin package Product Description The ANADIGICS AMT8650 is a low cost optical receiver capable of operation to 10Gb/s. A high performance PIN photodiode and a low noise, high gain transimpedance pre-amplifier (TIA) are incorporated in a hermetic, high speed header. The bandwidth is 8.5Ghz and dynamic range is over 22dB. High gain of the TIA eliminates the need for a separate post amplifier in most applications. These devices are readily designed into receivers, transceivers and transponders for SONET OC192/SDH STM-64 and 10 Gigabit Ethernet.
