DVI / HDMI Extender
GS8000 Data Sheet
Proprietary and Confidential 25544 - 3 May 2005 1 of 16
Key Features
? extends cable length of the TMDS and DDC channels of
a DVI or HDMI link
? DVI 1.0-compliant and HDMI 1.1-compliant input and
output signalling
? one device supports a complete single link DVI 1.0 or
HDMI interface (two devices for a dual link DVI interface)
? operational at TMDS rates from 252Mb/s to 1.65Gb/s
? supports display resolutions up to UXGA at 60Hz in 24-bit
true colour pixel format
? integrated user-tunable input termination resistors
? automatic identification of link inactivity with carrier detect
output
? output signal swing adjustable from 200mV to 2000mV
differential into 100? load
? output enable function
? superior noise immunity
? small footprint (44-pin QFN)
Applications
A DVI or HDMI input that will only be connected to a DVI
output with launch amplitude between 800mV and
1200mV differential. Since many DVI graphics cards
transmit at amplitudes outside this range, the GS8000
is not recommended for a generic DVI input.
Description
The GS8000 is Gennum’s DVI 1.0-compliant and HDMI
1.1-compliant automatic cable extender. When used in
front of a DVI/HDMI receiver, it produces a receive
solution with longer cable length. A DVI link of 20 to 30
metres at UXGA 60Hz (162Mb/s) can be realized with
the GS8000 provided the DVI transmitter is within the
DVI specification for jitter and voltage swing and that
high quality DVI cable is used.
The GS8000 contains an Output Enable input and
Carrier Detect output to allow for auto muting of the
clock and data outputs upon link inactivity.
Excellent power supply and common mode noise
rejection is employed to ensure robust operation in
noisy environments. The differential outputs are
adjustable and compatible with the DVI 1.0 and
HDMI 1.1 receiver specifications for input common
mode voltage and swing.
The GS8000 is designed in a CMOS process requiring
a 3.3V power supply. The analog I/O and digital core
power supply voltages may be individually provided.
