Limiting Transimpedance Amplifier DIE

The ONET8541T is a high-speed, high gain, limiting transimpedance amplifier used in optical receivers with data rates up to 11.3Gbps. It features low input referred noise, 9GHz bandwidth, 4kO small signal transimpedance, and a received signal strength indicator (RSSI).The ONET8541T is available in die form, includes an on-chip VCC bypass capacitor and is optimized for packaging in a TO can.The ONET8541T 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.
