LMH0344

3 Gbps HD/SD SDI Adaptive Cable Equalizer

General Description

Features

■

The LMH0344 3 Gbps HD/SD SDI Adaptive Cable Equalizer

is designed to equalize data transmitted over cable (or any

media with similar dispersive loss characteristics). The equal-

izer operates over a wide range of data rates from 125 Mbps

to 2.97 Gbps and supports SMPTE 424M, SMPTE 292M,

SMPTE 344M, and SMPTE 259M.

SMPTE 424M, SMPTE 292M, SMPTE 344M, and SMPTE

259M compliant

Supports DVB-ASI at 270 Mbps

■

Wide range of data rates: 125 Mbps to 2.97 Gbps

Equalizes up to 120 meters of Belden 1694A at 2.97 Gbps,

up to 140 meters of Belden 1694A at 1.485 Gbps, or up to

400 meters of Belden 1694A at 270 Mbps

The LMH0344 implements DC restoration to correctly handle

pathological data conditions. The equalizer may be driven in

either a single ended or differential configuration.

Equalizes 0-120m of Belden 1694A at 2.97 Gbps with

0.3 UI maximum output jitter

Manual bypass and output mute with a programmable

threshold

■

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.

Single-ended or differential input

■

50Ω differential outputs (internal 50Ω pullups)

Single 3.3V supply operation

The device is available in two space–saving packages: a 4 X

4 mm 16-pin LLP and even more space–efficient 3 x 3 mm

25-ball MICRO-ARRAY package.

280 mW typical power consumption

16-pin LLP or 25-ball MICRO-ARRAY package

Industrial temperature range: −40°C to +85°C

HBM ESD Rating: 8 kV

LLP version footprint compatible with the LMH0044 and

LMH0074

Replaces the Gennum GS2974A or GS2974B

■

Applications

SMPTE 424M, SMPTE 292M, SMPTE 344M, and SMPTE

259M serial digital interfaces

■

Serial digital data equalization and reception

■

Data recovery equalization
