The ONET8531T is a high-speed and high-gain limiting-transimpedance amplifier, used in optical receivers with

data rates up to 12.5 Gbps. It features low input referred noise, 10 GHz bandwidth, 4.5 k

Ω small signal

transimpedance, and a received signal strength indicator (RSSI).

The ONET8531T is available in die form, includes an on-chip VCC bypass capacitor and is optimized for

packaging in a TO can.

The ONET8531T requires a single +3.3V ± 10% supply and its power efficient design typically dissipates less

than 105 mW. The device is characterized for operation from –40

°C to 100°C case (IC back side) temperature.
