GS8000 DVI / HDMI Extender GS8000 Data Sheet Key Features 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. • • • • • • • • • • 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 100Ω load output enable function superior noise immunity small footprint (44-pin QFN) 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. 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. 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.

Detailed Description 3.1 Differential Inputs The GS8000 contains four current mode differential signal input buffers. These allow the device to be connected to a DVI 1.0 compliant data stream consisting of three transition minimized differential signals (TMDS) and a clock signal at one tenth the data rate. All input buffers have internal user programmable input termination pull-up resistors. A resistor value of 500Ω should be connected between the EXT_RES pin and D_GND to set the input termination to 50Ω. The input buffers use a separate power supply of +3.3V DC (VDD and GND) and have a wide common mode operating point. 3.2 LONG REACH™ DVI / HDMI 3.2.1 LONG REACH™ TMDS Gennum’s patented DVI technology restores the received signals to the input level defined in the DVI 1.0 and HDMI 1.1 specifications. Four gain stages are provided, three of which extend TMDS data at rates from 250Mb/s to 1.65Gb/s. The fourth gain stage is optimized to extend the clock signal at one tenth the received TMDS data rate. These stages operate under the assumption that the input signal was launched at an amplitude of between 800mV and 1200mV differential. 3.2.2 LONG REACH™ DDC The DDC Extend block manages DDC traffic in both directions by restoring incoming signals and boosting outgoing signals to meet the DDC specification. Connect the DDC_SDA and DDC_SCL pins to the DDC bus at the closest location to the GS8000. See Figure 3-2: LONG REACH™ DVI or HDMI Receive Solution. NOTE: If a level shifter is necessary, the GS8000 must be placed on the 5V side (connector side) as shown in Figure 3-2: LONG REACH™ DVI or HDMI Receive Solution. NOTE: The 5V present on the DVI and HDMI connectors can be significantly reduced over long ranges of cable. Therefore, it is recommended that this voltage not be used as the supply voltage for the LONG REACH™ DDC. Proprietary and Confidential 25544 - 3 May 2005 9 of 16 GS8000 Data Sheet 3.3 Differential Outputs The GS8000 contains four current mode differential signal output buffers capable of driving a DVI 1.0-compliant or HDMI 1.1-compliant receiver. The TMDS outputs are compatible with the DVI 1.0 or HDMI 1.1 specifications for input common mode and swing. The signal swing of each output is adjustable from 200mV to 2000mV differential for a 100Ω load. An external 1% resistor connected from the OUT_SWING pin to GNDQ sets the differential output signal amplitude. NOTE: The differential outputs are designed to interface directly to a DVI 1.0-compliant or HDMI 1.1-compliant receiver. They are not buffered to drive any cable. All differential outputs can be muted by setting the OE pin LOW. In this case, the output buffers will become high impedance and device power will be reduced. The output buffers use a separate power supply of +3.3V DC at the VDDQ and GNDQ pins. 3.4 Signal Monitoring and Control The signal monitoring and control block analyzes the signal received at the RXC and RXC pins. 3.4.1 Sync Detect Output When a valid signal is detected at the RXC/RXC pins, the sync detect (SCDT) output pin will be set HIGH. 3.4.2 Output Enable The GS8000’s differential signal outputs may be muted by setting the OE pin LOW. This causes the output buffers to become high impedance. To implement an auto mute on loss of input function, the SCDT output pin can be connected externally to the OE input. Proprietary and Confidential 25544 - 3 May 2005 10 of 16 GS8000 Data Sheet 3.5 System Considerations 3.5.1 Device Power Up Because the GS8000 was designed to operate in a multi-volt environment, any power up sequence is allowed. The internal core and differential signal I/O buffers may be powered up in any order. Device pins may also be driven prior to power up without causing damage. 3.5.2 ESD Protection The GS8000 has 2kV ESD protection on all pins. In addition, the device was designed to work with ESD diodes on the input connectors. These external diodes work with the chip to significantly increase overall system ESD protection. The ESD diodes used in Gennum’s Application Reference Design (4.2 ESD Diodes) provide ESD protection of greater than 8kV through air (test conducted in accordance with IEC 61000-4-2 standard “Electrostatic Discharge Immunity Test”). 3.5.3 Cable Use The GS8000 was designed for best performance when used with DVI 1.0-compliant and HDMI 1.1-compliant cables meeting the approximate loss characteristic shown in Figure 3-1: Cable Loss Characteristic. 1M 0 10M 100M 1G 10G -10 15m Attenuation (dB) -20 -30 30m -40 -50 50m -60 -70 -80 Frequency (Hz) Figure 3-1: Cable Loss Characteristic While the GS8000 will extend a range of DVI cable types and qualities, the device gives optimum performance when used to extend high-quality cable. Important parameters to consider when choosing a high quality DVI cable include inter-pair and intra-pair skew. Cable length extension is maximized when cable with low inter-pair and intra-pair skew is used. The GS8000 does not add significant amounts of intra-pair or inter-pair skew. However, the skew added by some long DVI cables can exceed the tolerance of some DVI receivers.

The GS8000 must always be used with a DVI receiver. Do not concatenate two equalizers without reclocking in between. If the GS8000 is to be used directly in front of another device with internal equalization, disable the equalization on that device. 2. Adding proper decoupling capacitors between power supplies and ground is critical to the proper performance and operation of the GS8000.

The following layout recommendations are to ensure optimal performance of the GS8000. • Signal traces for TMDS DATA and CLOCK channels must be 100Ω differential controlled impedance traces. • Differential signal trace spacing should be kept consistent throughout the entire trace length. Traces should be curved to minimize impedance changes. • An FR-4 dielectric may be used. • The GS8000 should be placed as close as possible to the input connector, and the trace length from connector to device should be kept as short as possible. • All differential signal traces should be kept on the same PCB layer as the GS8000. • External ESD protection diodes should be fast switching with a small terminal capacitance (less than or equal to 2pF). Panasonic’s MA157A or similar switching diodes are recommended. • Placing sufficiently large power and ground planes in board layout is critical to the proper performance and operation of the GS8000. 5.
