GS8000

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.

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 of GS8000 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.
