output phase of ADF4159 PLL

Dear Sir

 

Please can you tell me if there is a way of synchronizing the output phase of an ADF4159 based PLL? For example operate at one frequency, change the frequency to another frequency, then change back to the first frequency and obtain the same phase relationship between the output signal and the reference signal? Would using the sigma delta reset function, DB14 of Function register R3, ensure this condition? Are there any ramifications when using this function?

 

Thanks

John
