Can any one suggest, how to calculate the MOD and FRAC values for ADF4351 manually?
I'm able to get the MOD value for certain frequencies when i am using the below formula
MOD=PFD Frequency/Channel spacing*1000
But i'm unable to get the correct values if i'm using the above formula for certain frequencies like 3851MHz,1254MHz,2704MHz,....etc
Is there any other formula to calculate MOD and FRAC values manually?
