AD9162 : Changing CLK frequency

Hello ,

I have a question from our customer about changing clock frequency for AD9162 CLK input.

He use AD9162 as NCO only mode. (He does not use SERDES data inputs)

He said, he will change the ferquency of CLK while the AD9162 is running.

And he asks me,

  " After change the CLK frequency, I will set new value to FTW register. If I need to set other register, please let me know."

Does he need more configuration for AD9162 other than updating FTW register ?

Best regards,
