Features - - - - - - - - - - - extends cable length of the TMDS and DDC channels of a DVI or HDMI link DVI 1.0-pliant and HDMI 1.1-pliant input and output signalling one device supports a plete 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 200m V to 2000m V differential into 100Ω load output enable function superior noise immunity small footprint (44-pin QFN) Description The GS8000 is Gennum’s DVI 1.0-pliant and HDMI 1.1-pliant 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 mon mode noise rejection is employed to ensure robust operation in noisy environments. The differential outputs are adjustable and patible with the DVI 1.0 and HDMI 1.1 receiver specifications for input mon mode voltage and swing. Applications A DVI or HDMI input that will only be connected to a DVI output with launch amplitude between 800m V and 1200m V differential. Since many DVI graphics cards The GS8000 is designed in a CMOS process requiring transmit at amplitudes outside this range, the GS8000 . a 3.3V power supply. The analog I/O and digital core is not remended for a generic DVI input. power supply voltages may be individually provided. Data Shee Signal Monitor & Control oe SCDT RXC RXC LONG...
