New Contributorhello good afternoon, I am facing the same problem, I apply the formula that you showed objF = ((End*(M+Mdec)/(N*C))-Fout)^2. but it does not work for me, I carry out the series of steps indicated by the calculator in the plls manual but it does not give me the one I want for the intel pll, how can I know what to calculate to do with the M, N and C counters in the manual, to obtain the output what do I want. Thanks in advance for contributing.
