LMH0044

SMPTE 292M / 259M Adaptive Cable Equalizer

General Description

Features

■

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 125 Mbps to 1.485 Gbps and supports

SMPTE 292M, SMPTE 344M and SMPTE 259M.

SMPTE 292M, SMPTE 344M and SMPTE 259M

compliant

Supports DVB-ASI at 270 Mbps

■

Data rates: 125 Mbps to 1.485 Gbps

Equalizes up to 200 meters of Belden 1694A at 1.485

Gbps or up to 400 meters of Belden 1694A at 270 Mbps

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.

Manual bypass and output mute with a programmable

threshold

■

Single-ended or differential input

■

50Ω differential outputs

Single 3.3V supply operation

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.

208 mW typical power consumption with 3.3V supply

Replaces the GS1574 and GS1574A

Applications

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

digital interfaces
