DESCRIPTION
The ONET8501T is a high-speed, high gain, limiting transimpedance amplifier used in optical receivers with data
rates up to 12.5Gbps. It features low input referred noise, 10GHz bandwidth, 7kΩ small signal transimpedance,
and a received signal strength indicator (RSSI).
The ONET8501T is available in die form, includes an on-chip VCC bypass capacitor and is optimized for
packaging in a TO can.
The ONET8501T requires a single 3.3V ±10% supply and its power efficient design typically dissipates less than
105mW. The device is characterized for operation from –40°C to 100°C case (IC back side) temperature.
