I am giving analog RGB input to the digitizer (used both ADV7441A and ADV7403).
Input Video specifications are:
Format : Stanag 3350B Analog RGB (with SOG)
Hsync frequency : 15625Hz
Vsync frequency : 25Hz
Video Type : Progressive
No. of Horizontal Pixels : 512 (active + non active)
No. of Vertical lines : 625 (active + non active)
Considering these specifications, we set PLL DIV RATIO =512
and on output side we get PIXEL CLK (DATA CLK) = 8MHz
HSync = 15625Hz
VSync = 25Hz
Now if i change PLL DIV RATIO to 1024, PIXEL CLK will be 16MHz
What will happen to the video, will it look noisy or fine?
