GENLINX^™ GS9004D
Serial Digital Cable Equalizer
DATA SHEET
FEATURES
• automatic cable equalization
• typically greater than 300 m of high quality cable at
270 Mb/s
DEVICE DESCRIPTION
The Gennum GS9004D is an improved monolithic automatic
cable equalizer developed for SMPTE/EBU scrambled
NRZI Serial Di g i t a l Video signals.
• typically 300 m of high quality cable at 360 Mb/s
While there are no plans to discontinue the GS9004D,
Gennum has developed a successor product with improved
• drop in replacement for GS9004C
W • capability to drive 50 loads (to V_TT)
D • fully compatible with SMPTE 259M and operational to
400 Mb/s
E _{• signal strength indicator}
D _{• output 'eye' monitor}
N ^S • 14 pin SOIC packaging
E ^{N • single +5 or -5 volt power supply operation}
• Pb-free and Green
M _{IG APPLICATIONS}
M S ^{• Front-end cable equalization for digital video systems}
• Input equalization for serial digital distribution amplifiers,
O ^E routers, production switchers and other receiving
equipment
C ^D _{ORDERING INFORMATION}
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 Ω 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.
