AMT8302
Preliminary Data Sheet - Rev 0
FEATURES * Differential Output TIA * 3.3V Operation * Automatic Gain Control * Integrated 850nm MSM Detector & TIA * TO-56 Ultra Flat-Window Hermetic Package * High Reliability APPLICATIONS * 2x Fibre Channel (2.125 Gb/s) T56F TO-56 Ultra Flat Window Package
Product Description The ANADIGICS AMT8302 is a 3.3V monolithically integrated Metal-Semiconductor-Metal (MSM) photodetector and transimpedance amplifier (TIA) used to convert an 850nm input optical signal into a differential output voltage, and is manufactured in ANADIGICS 6 GaAs wafer fabrication facility. The integrated MSM and TIA receiver maximizes the receiver performance by minimizing the photodetector input parasitics to the TIA and
internally biasing the photodetector to achieve high sensitivity, bandwidth and overload performance. As an integrated product the reliability is inherently better than a discrete solution, and both the MSM-TIA integrated circuit and TO56 flat window packaged receiver pass stringent reliability requirements. These products are readily designed into receiversand transceivers for 2X Fibre Channel applications.
