Preliminary specification
YUV-to-RGB Digital-to-Analog
Converter (DAC)
SAA7167
FUNCTIONAL DESCRIPTION
The SAA7167 contains a video data path, 3 analog mixers
and voltage output amplifiers for the RGB channels
respectively, a keying control block as well as an I
2
C-bus
control block.
Video data path
The video data path includes a video data re-formatter, a
YUV-to-RGB colour space conversion matrix, and triple
8-bit DACs.

FORMATTER
The re-formatter de-multiplexes the different video formats
YUV 4 : 1 : 1, 4 : 2 : 2 or 2 : 1 : 1 to internal YUV 4 : 4 : 4,
which can then be processed by the RGB matrix. The pixel
byte sequences of those video input formats are shown in
Tables 1 to 4.
