LMH0394

3G HD/SD SDI Low Power Extended Reach Adaptive Cable

Equalizer

General Description

Features

The LMH0394 3 Gbps HD/SD SDI Low Power Extended

Reach Adaptive Cable Equalizer is designed to equalize data

transmitted over cable (or any media with similar dispersive

loss characteristics). The equalizer operates over a wide

range of data rates from 125 Mbps to 2.97 Gbps and supports

SMPTE 424M, SMPTE 292M, SMPTE 344M, SMPTE 259M,

and DVB-ASI standards.

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

■

259M, and DVB-ASI compliant

Equalized cable lengths (Belden 1694A): 200m at 2.97

Gbps, 220m at 1.485 Gbps, and 400m at 270 Mbps

■

Ultra low power consumption: 115 mW (normal operation)

■

Power save mode with auto sleep control (17 mW typical

power consumption in power save mode)

The LMH0394 provides extended cable reach with improved

immunity to crosstalk and ultra low power consumption. The

equalizer includes active sensing circuitry that ensures robust

performance and enhanced immunity to variations in the input

signal launch amplitude. The output driver offers pro-

grammable de-emphasis for up to 40” of FR4 trace losses.

The LMH0394 includes power management to further reduce

power consumption when no input signal is present.

Designed for crosstalk immunity

■

Output de-emphasis to compensate for FR4 board trace

losses

Digital and analog programmable MUTE_REFthreshold

■

Optional SPI register access

Input data rates: 125 Mbps to 2.97 Gbps

Internally terminated 100Ω LVDS outputs with

programmable output common mode voltage and swing

Programmable launch amplitude optimization

Cable length indicator

The LMH0394 supports two modes of operation. In pin mode,

the LMH0394 operates with control pins to set its operating

state, and is footprint compatible with the LMH0384,

LMH0344, and legacy SDI equalizers. In SPI mode, an op-

tional SPI serial interface can be used to access and configure

multiple LMH0394 devices in a daisy-chain configuration.

This allows programming the output common mode voltage

and swing, output de-emphasis level, input launch amplitude,

and power management settings, as well as access to a cable

length indicator and all pin mode features.

■

Single 2.5V supply operation

16-pin LLP package

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

Footprint compatible with the LMH0384 and also the

LMH0344, LMH0044, and LMH0074 in pin mode.

Applications

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

259M serial digital interfaces

■

Broadcast Video routers, switchers, and distribution

amplifiers
