Anadigics introduces an integrated fiber receiver designed for use in small form factor (SFF) modules for Gigabit Ethernet and Fibre Channel fiber optic networks. The AMT128503T56F offers systems designers a high-performance solution for 850 nm systems in a small TO-56 package suitable for SFF modules, enabling increased board density in next-generation datacom transceivers. It consists of a monolithically integrated metal-semiconductor-metal (MSM) diode and a transimpedance amplifier (TIA) integrated in a small TO056 package. The device offers typical sensitivity of -22 dBm and a minimum responsivity of 1,000 V/W with a total power dissipation of about 120 mW. Operating from a 3.3 VDC supply, the device provides a minimum bandwidth of 1.0 GHz and features an on-chip automatic gain control circuit enabling it to handle optical input powers up to 0 dBm.
