The ONET8551T device is a high-speed, high-gain, limiting transimpedance amplifier used in optical receivers with data rates up to 11.3 Gbps. It features low-input referred noise, 9-GHz bandwidth, 10-kΩ small signal transimpedance, and a received signal strength indicator (RSSI.

The ONET8551T device is available in die form, includes an on-chip VCC bypass capacitor, and is optimized for packaging in a TO can.

The ONET8551T device requires a single +3.3-V supply. The power-efficient design typically dissipates less than 95 mW. The device is characterized for operation from –40°C to 100°C case (IC back-side) temperature.
