GS9024 GENLINX™

Automatic Cable Equalizer

GS9024 Data Sheet

Features

Description

•

automatic cable equalization

fully compatible with SMPTE 259M

typically equalizes greater than 350m of high

quality cable at 270Mb/s

signal strength indicator

output data muting when input data is lost

output 'eye' monitor (OEM) with large signal

amplitude and power down option

low power: 240mW at 5V

14 pin SOIC package

programmable output data squelch for max cable

length limiting

The GS9024 is a high performance automatic cable

equalizer designed for serial digital data rates from

143Mb/s to 540Mb/s. The GS9024 receives either

single-ended or differential serial data and outputs

equalized differential signals at PECL levels (800mV).

The GS9024 provides up to 40dB of gain at 200MHz

which will typically result in equalization of greater than

350m at 270Mb/s of Belden 8281 cable.

•

The GS9024 incorporates an analog signal strength

indicator/carrier detect (SSI/CD) output indicating both

the presence of a carrier and the amount of equalization

applied to the signal. Optional external resistors allow

the carrier detect threshold level to be customized to the

user's requirement.

•

carrier detect with programmable threshold level

serial data output "High Z" select to allow muxing of

EQ inputs

The GS9024 also features selectable High Z serial data

outputs eliminating the need for input muxing circuitry in

routers. In addition, the GS9024 provides an 'Output

Eye Monitor' (OEM) which allows the verification of

signal integrity after equalization, prior to reslicing.

•

Pb-free and Green

Applications

The GS9024 operates from a single +5V or -5V power

supply and consumes only 240mW of power. Packaged

in a small 14 pin SOIC, the GS9024 is ideal for router

applications where high density component placement

is required.

Front-end cable equalization for digital video systems;

Input equalization for serial digital distribution

amplifiers, routers, production switchers and other

receiving equipment.
