APPLICATIONS

Front-end cable equalization for digital video systems; Input

equalization for serial digital distribution amplifiers, routers,

production switchers and other receiving equipment.

DESCRIPTION

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.

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.

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.
