Optical Receiver Operates At Fibre Channel Data Rates

The AMT8301T46F/L rate-agile optical receiver solution offers the unique ability to operate at 1x and 2x Fibre Channel data rates. This integrated photodetector and transimpedance amplifier is made using the company's LPIII manufacturing process, a MESFET process that includes MSM photodiodes. The process yields circuits that operate at low voltages with low power dissipation. As a result of this process, the optical receiver demonstrates a sensitivity of better than -19 dBm over voltage and temperature at 1.0625 and 2.125 Gb/s data rates and at a supply voltage of 3.3V with less than 45 mW power dissipation. To support the coupling requirements of various transceiver designs, packaging options include either a TO-46 ultra-flat window or a ball lens packaging. A TO-56 package will also be available.
