LMH0384

3 Gbps HD/SD SDI Extended Reach and Configurable

Adaptive Cable Equalizer

General Description

Features

The LMH0384 3 Gbps HD/SD SDI Extended Reach and Con-

figurable Adaptive Cable Equalizer is designed to equalize

data transmitted over cable (or any media with similar disper-

sive 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, and SMPTE

259M standards.

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 140 meters of Belden 1694A at 2.97 Gbps,

up to 200 meters of Belden 1694A at 1.485 Gbps, or up to

400 meters of Belden 1694A at 270 Mbps

The LMH0384 includes active sensing features and design

enhancements including longer cable equalization, lower out-

put jitter, configurable pin mode and SPI modes, a power-

saving sleep mode, and programmable output common mode

voltage and swing. The LMH0384 implements DC restoration

to correctly handle pathological data conditions.

Power save mode with auto sleep control (35 mW typical

power consumption in power save mode)

■

Optional SPI register access

■

Manual bypass and output mute with a programmable

threshold

Internally terminated 100Ω LVDS outputs with SPI

■

The LMH0384 includes an auto sleep mode to power down

the device when no input signal is detected. Other features

include separate carrier detect and output mute pins which

may be tied together to mute the output when no input signal

is present, and a programmable mute reference which may

be used to mute the output at a selectable level of signal

degradation.

programmable output common mode voltage and swing

Programmable launch amplitude optimization in SPI mode

Cable length indicator in SPI mode

Single 3.3V supply operation

■

16-pin LLP package

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

The LMH0384 supports two modes of operation. In pin mode

(non-SPI mode) the LMH0384 is footprint compatible with the

LMH0344 and legacy SDI equalizers. In the optional SPI

mode, the LMH0384 provides register access to all of its fea-

tures along with a cable length indicator, programmable out-

put common mode voltage and swing, and launch amplitude

optimization.

Footprint compatible with the LMH0344, LMH0044, and

LMH0074 in pin mode.

Applications

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

■

259M serial digital interfaces

Serial digital data equalization and reception

The device is available in a 16-pin LLP package.
