ONET8521T - A 9 GHz, 2.4 KOhms Transimpedance Amplifier with RSSI

The ONET8521T is a high-speed, limiting transimpedance amplifier used in optical receivers with data rates up to 11.3Gbps. It features low input referred noise, 9GHz bandwidth, 2.4kΩ small signal transimpedance, and a received signal strength indicator (RSSI).

The ONET8521T is available in die form, includes an on-chip V_CC bypass capacitor and is optimized for packaging in a TO can.

The ONET8521T requires a single 3.3V ±10% supply and its power efficient design typically dissipates less than 90mW. The device is characterized for operation from –40°C to 100°C case (IC back side) temperature.
