DAC MAPPING
Depends on the video output mode, the color bars mapping to DAC are specified in Table 7, Table 8 and
Figure 12, Figure 13. Where white is 400. For PAL-BDGHINc blank = 120. For NTSC/PAL-M blank = 114 (setup
= 0), 1 IRE = 2.857; if setup = 1, blank = 112, 1 IRE = 2.8.
Typical with 37.5Ω load, vref_o = vref_i, SETUP = 0
100% saturation color bars.
