I have request with ADV7343 for SD RGB 24bit, 720x480 resolution, interlace, Vsync=29.97Hz as Table 1 and Table 36 of data sheet
I meet a challenge that video processor can't output 27MHz pixel clock output. Hsync and Vsync output are ok to follow standard.
May I add a external precision crystal with 27MHz output to pixel clock pin of ADV7343?
Now I am worry about the data bus and pixel clock sync problem.
Do you have this kind experience or some suggestion to me? Thank you.
