How to program/configure ADF5356 with out using the evaluation board?
In the documentation of the Xmicrowave PCB it says: -


  Control of all on-chip registers is through a simple 3-wire interface


And in the ADF5356 data sheet it shows this: -



So you need to add an MCU that can send serial data to the ADF5356 via the three wire port highlighted in red. All ADi's range of fractional and integer PLLs use the same method so if something isn't clear on one data sheet go look on another like the ADF4002 or the ADF4111 (simpler devices that use the same interface).
