DEVICE DESCRIPTION

The Gennum GS9004C is an improved monolithic automatic

cable equalizer developed for SMPTE/EBU scrambled

NRZI Serial Di g i t a l Video signals.

While there are no plans to discontinue the GS9004C,

Gennum has developed a successor product with improved

features and performance called the GS9024. The GS9024

is recommended for new designs.

This device features DC restoration to pass the Pathological

Test Signals and fully automatic equalization in order to

meet the SMPTE 259M Serial Interface Standard. The

DATA and DATA outputs typically deliver 800 mV (p-p)

equalized signals into 50

can be used to feed cable driver circuits for Serial Distribution

Amplifier applications.

This device also incorporates an analog signal strength

indicator (SSI) which provides a 0.5 V to 0 V output relative

to V

to the signal.

The

(OEM), which allows verification of signal integrity after

equalization, prior to reslicing. Operating with a single +5

or -5 volt supply, the GS9004C typically draws 52 mA of

current.
