www.DataSheet4U.com LMH0024 SMPTE 259M / 344M Adaptive Cable Equalizer PRELIMINARY February 2006 LMH0024 3.3V SMPTE 259M / 344M Adaptive Cable Equalizer General Description The LMH0024 SMPTE 259M / 344M 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 540 Mbps and supports SMPTE 259M and SMPTE 344M. The LMH0024 implements DC restoration to correctly handle pathological data conditions. DC restoration can be bypassed for low data rate applications. The equalizer is flexible in allowing either single-ended or differential input drive. Additional features include a mute pin which can be used to manually mute the output and a cable length indicator which determines the amount of cable being equalized.
