It is a question about ADF4155.
Perhaps this might be a stupid question for you, I apologize in advance.

I read the datasheet.(Data Sheet ADF4155 Rev. 0)
I caught on the explanation about N counter.

The value of FRAC2 is written as 1 to 16,383.
Does FRAC2 should not be zero?
Why is it forbidden?

Best regards
