LMH0044
SMPTE 292M / 259M Adaptive Cable Equalizer
General Description
The LMH0044 SMPTE 292M / 259M 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 143 Mbps to 1.485 Gbps and supports
SMPTE 292M, SMPTE 344M and SMPTE 259M.
The LMH0044 implements DC restoration to correctly handle
pathological data conditions (DC restoration may be by-
passed for low data rate applications). The equalizer may be
driven in either a single ended or differential configuration.
Additional features include separate carrier detect and output
mute pins which may be tied together to mute the output when
no signal is present. A programmable mute reference is pro-
vided to mute the output at a selectable level of signal degra-
dation.
