DESCRIPTION

The ONET8551T device is a high-speed, high-gain,

limiting transimpedance amplifier used in optical receivers with data rates up to 11.3 Gbps. It features

low-input referred noise, 9-GHz bandwidth, 10-kΩ

small signal transimpedance, and a received signal

strength indicator (RSSI).

The ONET8551T device is available in die form,

includes an on-chip VCC bypass capacitor, and is

optimized for packaging in a TO can.

The ONET8551T device requires a single +3.3-V

supply. The power-efficient design typically dissipates

less than 95 mW. The device is characterized for

operation from –40°C to 100°C case (IC back-side)

temperature.
