Leakage Current in ADIsimPLL

ADI PLL team,

 

What should I put for Phase Detector Leakage setting in ADIsimPLL? I am using ADF4155. According to ADF4351 leakage current, the leakage current of ADI PLL ICs are around ±1 nA. Is this true for ADF4155?

What happens if there is an OPAMP in the loop? Should I include the input bias current of the OPAMP?

Thanks.
