SMPTE 292M / 259M Adaptive Cable Equalizer

General Description

The LMH0034 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 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 al-

lowing either single-ended or differential input drive.

Additional features include a combined carrier detect and out-

put 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.
