7.2.4VESA DDSC2B and DPMS Support

The Video Processor supports VESA, DDSC2B, and DPMS standards for enhanced monitor communications and power management support. This support is provided via signals DDC_SCL (muxed with IDE_DATA10) and DDC_SDA (muxed with IDE_DATA9). F4BAR0+Memory Offset 04h[24, 23, 22] controls the interface.

7.2.5Integrated DACs

The Video Processor uses a Digital to Analog Converter (DAC) for CRT display.

To interface directly with the CRT display, the Video Pro- cessor incorporates triple 8-bit video DACs. The integrated DACs drive the RED, GREEN and BLUE inputs of the CRT. Each integrated DAC is an 8-bit current output type which can run at a clock rate of up to 135 MHz. The integrated

DAC can generate voltage levels from 0 to 1.0V, when driv- ing 75Ω double-terminated loads.

Differential and integral linearity errors, over full tempera- ture and voltage ranges, are less than one LSB.

The peak white voltage (VFR - full range output voltage), generated at the DAC, is defined according to the following formula:

VFR = 3.35(VREF / RSET)*75

where:

VREF is the voltage at VREF (either internal bandgap refer- ence, or externally connected voltage reference).

RSET is the value of resistance between SETRES and AVSS (typically 470Ω).
