Hello,

I have questions about CMRR characteristics across frequency of ADV7282-M.

 

Question 1:
  "AN-1191.pdf" includes the information of ADV7182.
  http://www.analog.com/media/en/technical-documentation/application-notes/AN-1191.pdf

  Does ADV728x have same (similar) CMRR characteristics to ADV7182?
  In the other word, are the figure 2,3,5 and 6 on AN-1191 also applied to ADV728x?

 

Question 2:
  If you know any effective method (H/W or register setting) for improving CMRR performance, please let me know it.
  (We know an accuracy of input network resistance (1.3k/430ohm) is important. So we want to know the other method.)

 

Thank you!
Best regards.
