The ONET8551T is an 11.3-Gbps limiting transimpedance amplifier with RSSI

The ONET8551T device is an AD9238BST-20 high speed, high gain, limiting transimpedance amplifier for optical receivers at data rates up to 11.3 Gbps. It features low input-referred noise, 9GHz bandwidth, 10kΩ small-signal transimpedance, and a received signal strength indicator.

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

The ONET8551T device requires a +3.3V power supply. Power-efficient designs typically consume less than 95 mW. The device features a case (backside of the IC) temperature range of –40°C to 100°C.
