Hi,


Sorry for the delay. Yes, you are right. I am referring to the XCVR user recalibration. If I understand it correctly, in C10 device, the Native PHY is a separate entity from the SDI II IP. You can perform the user recalibration through the dynamic reconfiguration AVMM interface.


As for the interference with the HDMI IP, sorry as I am not sure what might be wrong. Just wonder if you have tested using CMU PLL for the SDI and placing the SDI and HDMI in different XCVR banks just to help narrowing down the issue.


Please let me know if there is any concern. Thank you.



Best regards,
