LMH0044 Datasheet Adaptive Cable Equalizer

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: www.DataSheet4U.com LMH0044 SMPTE 292M / 259M Adaptive Cable Equalizer PRELIMINARY April 2006 LMH0044 SMPTE 292M / 259M Adaptive Cable.

General Description

The LMH0044 SMPTE 292M / 259M adaptive cable equalizer is a monolithic integrated circuit for equalizing 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 1.485 Gbps and supports SMPTE 292M, SMPTE 344M and SMPTE 259M.

The LMH0044 implements DC restoration to correctly handle pathological data conditions (DC restoration may be bypassed for low data rate applications).

Key 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 n SMPTE 292M, SMPTE 344M and SMPTE 259M compliant n Supports DVB-ASI at 270 Mbps n High data rates: 143 Mbps to 1.485 Gbps n Equalizes up to 140 meters of Belden 1694A at 1.485 Gbps or up to 350 meters of Belden 1694A at 270 Mbps n Manual bypass and output m.
