OQ2538U - SDH/SONET STM16/OC48 main amplifiers

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).

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.
