7.2.4

VESA 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). Memory
Offset 04h[24, 23, 22] controls the interface.

7.2.5

Integrated 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 75

Ω

 double-terminated loads.

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

The peak white voltage (V

FR

 - full range output voltage),

generated at the DAC, is defined according to the following
formula:

V

FR

 = 3.35(V

REF 

/ R

SET

)

*

75

where:

V

REF 

is the voltage at VREF (either internal bandgap refer-

ence, or externally connected voltage reference).

  R

SET 

is the value of resistance between SETRES and

AV

SS 

(typically 470

Ω

).
