I'm a bit confused about the phase adjust possibility in the ADF4350. It is not clear for me if the device runs with FRAC = 0 but with LDF = 0 (fractional-N digital lock detect) is it still possible to adjust the output phase by 360°/MOD?
If yes, do I have to set anything else than turning on Phase Resync in Register 3 and set an appropriate MOD and Phase value?
I'm running two devices in parallel fed by the same reference and I cannot see any change when I program the phase word with different values.
Could you give me some guidance?
