Product specification
OQ2538HP; OQ2538U
FEATURES
Differential 100 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
Low power dissipation (typically 270 mW)
Single 4.5 V supply voltage
Low cost LQFP48 plastic package.
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.
APPLICATIONS
Main amplifier in Synchronous Digital Hierarchy (SDH)
and Synchronous Optical Network (SONET) systems for
short, medium and long haul optical transmission
Level detector for laser diode control loops
Wideband RF gain block with internal level detectors.
