SAF7167AHW

YUV-to-RGB digital-to-analog converter

[1] I = input; I/O = input or output; O = output; S = supply.

7. Functional description

The SAF7167AHW 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.

7.1 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.

7.1.1 Re-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 Table 4 to Table 7.
