In a new card we developed, we use ADV7393 to produce PAL output S-VIDEO. As first stage of integration, we wanted to check TEST PATTERN, and found out that DAC2 at pin 27 of the component does not create video: DAC3 does create video.
The configuration, via I2C:
DAC3 video can be either Y or C, per swap at sub address 0x84.
With 0x00=1E there is an output also at DAC1.
