my customer has used ADV7181C in project, and he face a video image noise problem.
he tried to adjust the YSFM and Comb filter, but they are not any image effect
during his software find tuning, he would like to know how to know the Comb and YSFM filter work with image effect.
(Maybe image worse or better after adjst these filter)
What kind condition to adjust YSFM and Comb filter for Image find tuning?
2nd, per checked ADV7181C data sheet, there is no any description how much CVBS input voltage range can support?
Thank you very much.
