LMH0044

SMPTE 292M / 259M Adaptive Cable Equalizer

General Description

Features

n SMPTE 292M, SMPTE 344M and SMPTE 259M

compliant

The LMH0044 SMPTE 292M / 259M adaptive cable equal-

izer 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.

n Supports DVB-ASI at 270 Mbps

n High data rates: 143 Mbps to 1.485 Gbps

n Equalizes up to 140 meters of Belden 1694A at 1.485

Gbps or up to 350 meters of Belden 1694A at 270 Mbps

n Manual bypass and output mute with a programmable

threshold

n Single-ended or differential input

n 50Ω differential outputs

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 out-

put mute pins which may be tied together to mute the output

when no signal is present. A programmable mute reference

is provided to mute the output at a selectable level of signal

degradation.

n Single 3.3V supply operation

n 208mW typical power consumption with 3.3V supply

n Replaces the GS1574 and GS1574A

Applications

n SMPTE 292M, SMPTE 344M, and SMPTE 259M serial

digital interfaces

n Serial digital data equalization and reception

n Data recovery equalization
