At present, i want to use your company's phase-locked loop chip ADF4356 to generate a fixed frequency of 137.37MHz, reference frequency is 50MHz.
      When the parameter MOD2 is calculated from the datasheet of the ADF4356: MOD2=fPDF/GCD(fPDF,fCHSP), (datasheet page 12)
The question is: What we need to output is a fixed frequency. How is the value of fCHSP determined? How to determine the value of MOD2 and FRAC2?
