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.
