i explain my system first. it consist of adv7441a, ad9889b and a mcu. the mcu controls adv7441a and ad9889b by i2c. now cvbs signal goes through ad7441 and outputs 24bit rgb signal which is input to ad9889b, but ad9889b can not output dvi signal, i do not know why.
The hpd pin of ad9889b is pulled hign by me. I read back the registers values below. and you could check my schematic. Please give me some advice. Thaks.
initialize i/o
change to cvbs pal mode!
test 9889
