1.25 Gb/s 1310/1550nm PIN TIA
Data Sheet - Rev 0
FEATURES * 1.25 Gb/s Differential Output TIA * 5.0V Operation * Automatic Gain Control * 75mm 1270-1560nm InGaAs Photodetector * 1000 MHz Minimum Bandwidth * -28dBm Typical Sensitivity * TO-46 Ultra Flat-Window or Lens Package APPLICATIONS * Gigabit Ethernet (1.250 Gb/s) * Fibre channel (1.064 Gb/s) PRODUCT DESCRIPTION
The ANADIGICS AMT121302, packaged in a TO46 flat window or lens can, is a 5V integrated photodetector and transimpedance amplifier (TIA) used to convert a long wavelength (1270-1560nm) input optical signal into a differential output voltage, and is manufactured in ANADIGICS 6 GaAs wafer fabrication facility. The TIA maximizes the

receiver performance by providing a negative voltage to reverse bias the photodetector which allows the device to achieve high sensitivity and wide bandwidth. These products are readily designed into receivers and transceivers for Gigabit Ethernet and Fibre Channel applications.
