    Hello user4538329,

    can you please add some more information to your question?

    Are you using the CDCE62005 EVM?

    When you already placed a unit on your own PCB or breadboard: please share your schematic portion as well.

    Which frequency do you run for the SPI_CLK? Did you check the setup and hold times of the physical signal?


    Thanks!

    Best regards,

    Patrick
