DESCRIPTION
The CLC034 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 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 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.
