I want to build a synthesizer,with a variable PFD Ref Frequency(Fref) and variable integer Divider (N),the PLL output is Fout.
I want to know the relationships between the variable Fref and the variable Divider N.As we know Fout=NFref.But now the N and the Fref are variable,how to cal their ralationships?any references?Thank you!
