CLC034
SMPTE 292M / 259M Adaptive Cable Equalizer
General Description
The CLC034 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 CLC034 implements DC restoration to correctly handle
pathological data conditions. DC restoration can be by-
passed for low data rate applications. The equalizer is flex-
ible 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.
