LMH0395

3G HD/SD SDI Dual Output Low Power Extended Reach

Adaptive Cable Equalizer

General Description

Features

The LMH0395 3 Gbps HD/SD SDI Dual Output Low Power

Extended Reach Adaptive Cable Equalizer is designed to

equalize data transmitted over cable (or any media with sim-

ilar 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: 140 mW (dual outputs),

115 mW (single output)

■

Dual differential outputs; second output can be

independently powered down

■

The LMH0395 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 LMH0395 offers power man-

agement to further reduce power consumption when no input

signal is present.

Power save mode with auto sleep control (17 mW typical

power consumption in power save mode)

■

Designed for crosstalk immunity

■

Output de-emphasis to compensate for FR4 board trace

losses

Digital and analog programmable MUTE_REFthreshold

■

The LMH0395 has two differential serial data outputs, in-

creasing flexibility and eliminating the need for a fanout buffer

on the output in many applications. The outputs may be in-

dependently enabled and controlled. The output drivers offer

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

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

The LMH0395 supports two modes of operation. In pin mode,

the LMH0395 operates with control pins to set its operating

state. In SPI mode, an optional SPI serial interface can be

used to access and configure multiple LMH0395 devices in a

daisy-chain configuration. This allows programming the out-

put common mode voltage and swing, output de-emphasis

level, input launch amplitude, and power management set-

tings, as well as access to a cable length indicator and all pin

mode features.

Programmable launch amplitude optimization

Cable length indicator

■

Single 2.5V supply operation

24-pin LLP package

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

Applications

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

■

259M serial digital interfaces

Broadcast Video routers, switchers, and distribution

amplifiers
