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 125 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.
