SDH/SONET STM16/OC48 main amplifiers
Product specification
OQ2538HP; OQ2538U
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
• 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.
