The ONET2591TA is a high-speed transimpedance amplifier used in optical receivers with data rates up to 2.5 Gbps. It features a low input referred noise, 1.8-GHz bandwidth, automatic gain control (AGC), 2.6-kΩ transimpedance, and received signal strength indication (RSSI).
The ONET2591TA is a high-performance transimpedance amplifier designed for optical receivers operating at data rates up to 2.5 Gbps. Key features include a 1.8-GHz bandwidth, automatic gain control (AGC), received signal strength indication (RSSI), and a low input-referred noise of 6.6 pA/VHz. The device operates from a single 3.3-V supply and is characterized for temperatures from -40°C to 85°C.
The amplifier integrates a transimpedance stage, a voltage amplifier, and a CML output buffer with on-chip back-termination. It includes on-chip filtering for the photodiode supply and bias current generation. The device is available as a bare die optimized for use in a TO can package.
