LMH0344 - 3Gbps HD/SD SDI Adaptive Cable Equalizer

Description

The LMH0344 3Gbps HD/SD SDI Adaptive Cable Equalizer is designed to equalize data transmitted over cable (or any media with similar dispersive loss characteristics).

Features

  • include separate carrier detect and output mute pins which may be tied together to mute the output when no signal is present. A programmable mute reference is provided to mute the output at a selectable level of signal degradation. Features.
  • SMPTE 424M, SMPTE 292M, SMPTE 344M, and SMPTE 259M compliant.
  • Supports DVB-ASI at 270 Mbps.
  • High data rates: 143 Mbps to 2.97 Gbps.
  • Equalizes up to 120 meters of Belden 1694A at 2.97 Gbps, up to 140 meters of Belden 1694A at 1.485 Gbps.

LMH0344 3Gbps HD/SD SDI Adaptive Cable Equalizer PRELIMINARY April 2007 LMH0344 3Gbps HD/SD SDI Adaptive Cable Equalizer General Description The LMH0344 3Gbps HD/SD SDI Adaptive Cable Equalizer is designed to equalize data transmitted over cable (or any media with similar dispersive loss characteristics). The equalizer operates over a wide range of data rates from 143 Mbps to 2.97 Gbps and supports SMPTE 424M, SMPTE 292M, SMPTE 344M, and SMPTE 259M. The LMH0344 implements DC restoration to correctly handle pathological data conditions. The equalizer may be driven in either a single ended or differential configuration. Additional features include separate carrier detect and output mute pins which may be tied together to mute the output when no signal is present.
