Query about ADF4158 Simulation with ADIsimPLL

Dear supporter


I use the ADIsimPLL to simulate the ADF4158. I use the VCO library editor to define the 15GHz VCO I used and the VCO follows a divided by 4 ADF5001. The setting in the ADIsimPLL is shown as follow.

The problem is that the simulation result didn’t show the Freq Error. I just want to know how much error there supposes to be under this set mode and the datasheet in ADF4158 doesn’t contain the formulation to calculate the linearity of the output signal. Thank you.
