this
page
The OQ2538HP is a limiting amplifier IC intended for use as the main amplifier in 2.5 Gbits/s Non-Return
to Zero (NRZ) transmission systems (SDH/SONET).
Comprised of four amplifier stages with a total gain of 48.5 dB, it provides for a wide input signal dynamic
range at a constant CML-compatible output level.
Two level-detection circuits are provided for monitoring AGC and LOS input signal levels. An internal
automatic offset compensation circuit eliminates offset in the amplifier chain.
