    Hi,


    As I understand it, you have some inquiries related to the calibration sequence for the A10 XCVR blocks. For your information, you should refer to the Figure 284 and Figure 286 for the calibration sequence which should be ATX -> fPLL -> PMA. There should be some typo at the initial description. Sorry for the inconvenience.


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

Hi,

So from your view, I think that the switch to low sequence of cal_busy is ATX--> fPLL-->PMA according to the figure 284 & 286, right? If so, I think that's reasonable.
