I can see  in my design strange behavior linked to the profiles configuration on AD9913.The component configuration is:

16MHz input multiplied by 15 = 240MHz, switching mode, serial configuration (SPI 200kbps)


The issue is:


I configure profiles 0,1,2 following steps below:


Config of profile 0


RD check

Config of profile 1


RD check profile 1

Config of profile 2


RD check profile 2


I systematically read profile0 configuration in profile 1 and 2 registers even if:

- I program profiles 0, 1, 2 with different values

- OR I just program profile 0


I have not checked content of other profiles.

RD check is done on oscilloscope, adresses are correct. I program successfully CFR1 and CFR2.


MANY THANKS for feedback....
