DESCRIPTION
GENERAL DESCRIPTION
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.
