DATA SHEET
DEVICE DESCRIPTION
The Gennum GS9004D is an improved monolithic automatic
cable equalizer developed for SMPTE/EBU scrambled
NRZI Serial Digital Video signals.
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
loads (to V
TT
). These
signals 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
CC
, indicating the amount of equalization being applied
to the signal.
The GS9004D features an OUTPUT 'EYE' MONITOR
(OEM), which allows verification of signal integrity after
equalization, prior to reslicing. Operating with a single
+5 or -5 volt supply, the GS9004D typically draws 52 mA
of current.
