As this header, please share with us pll file (ADIsimPLL) and PCB file of evaluation board EV-ADF4360-5EB1Z and ADF5355SD1Z.
Thank in advanced!
Please search EZ using the attached link for the EVB CAD files.
I also attached a *.pll file but you'll need to download ADISimPLL from the website (ADF5355 Full Product Page) if you don't already have it in order to use it.
