The LMH0034 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 125 Mbps to 1.485
Gbps and supports SMPTE 292M, SMPTE 344M and SMPTE 259M.
The LMH0034 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 combined carrier detect and output mute pin which mutes the
output when no signal is present. A programmable mute reference is used to mute the output at a
selectable level of signal degradation. A cable length indicator is provided to determine the
amount of cable being equalized.
