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 transmit-
ted 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 al-
lowing 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.
