Description
The OQ2809 is a limiting amplifier IC designed for use as the main amplifier in 2.5 Gbits/s Non-Return to Zero (NRZ) transmission systems (SDH/SONET). It consists of four amplifier stages with a total gain of 48.5 dB, providing a wide input signal dynamic range at a constant CML-compatible output level. The IC also includes two level-detection circuits for monitoring AGC and LOS input signal levels and an internal automatic offset compensation circuit to eliminate offset in the amplifier chain.
Specifications and features
- Differential 100 Ω outputs for direct connection to Current-Mode Logic (CML) inputs
- Wide bandwidth (3 GHz)
- 48.5 dB limiting gain
- Noise figure typically 11 dB
- Automatic offset compensation
- Input level-detection circuits for Automatic Gain Control (AGC) and Loss Of Signal (LOS) detection
