Table 45:
(Output Level: Fine Adjustment in 1% Increments)
The programming option “Coarse Adjust” uses five separate bits [14:10] of I
independently adjust the output level of each R, G, B and CVBS DAC between 0.58 V
and 1.23 V (in increments of 21 mV, assuming an effective load of 75 Ω / 75 Ω= 37.5
Ω). Note that these five bits are not signed.
