| AMT8210 1.25 Gb/s 1310/1550nm PIN-TIA FEATURES * * * * * * * 1.25 Gb/s differential output TIA DC to 1000 MHz bandwidth +3.3V Operation -27dBm Typical sensitivity 1250-1620nm PIN Photodetector Automatic Gain Control (AGC) 0dBm Optical Overload APPLICATIONS * * * Gigabit Ethernet (1.25 Gb/s) Fiber Channel (1.0625 Gb/s) FTTx systems TO-46 4 pin Ball Lens Package TO-46 5 pin Ball Lens Package Product Description The ANADIGICS AMT8210, packaged in a TO46 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 AMT8210 has a bandwidth of 900MHz and a dynamic range of over 27dB. These devices are readily designed into receivers, transceivers and transponders for Gigabit Ethernet and Fiber Channel applications.
