GS2984 - Adaptive Cable Equalizer

Datasheet Summary

Description

The GS2984 is a high-speed BiCMOS integrated circuit designed to equalize and restore signals received over 75Ω coaxial cable.

The device is designed to support SMPTE 424M, SMPTE292M and SMPTE 259M, and is optimized for performance at 270Mb/s, 1.485Gb/s and 2.97Gb/s.

Features

  • SMPTE 424M, SMPTE 292M and SMPTE 259M compliant.
  • Automatic cable equalization.
  • Multi-standard operation from 143Mb/s to 2.97Gb/s.
  • Performance optimized for 270Mb/s, 1.485Gb/s and 2.97Gb/s. Typical equalized length of Belden 1694A cable:.
  • 140m at 2.97Gb/s.
  • 200m at 1.485Gb/s.
  • 400m at 270Mb/s.
  • Supports DVB-ASI at 270Mb/s.
  • Manual bypass (useful for low data rates with slow rise/fall times).
  • Programmable carrier detect wit.
