In AD9889B Programming Guide, It says Register 0x98 must be written to 0x07 for proper operation .But Out board hdmi output from AD9889B will have noise when output format is 1080p50 with this setting,some TV even can't recognise the ouput .we find if we increase the 0x98 setting, the noise will turn little . And now we set 0x98=0x0F, the output seem OK, and the TV can display well. But I wondering  is there some problem with this setting? what  maybe the problem 0x07 is not OK?

 

THANK YOU!
