After a performing a 'phase-resync' on the ADF4351, does changing the value in the phase register result in a continuous phase change at the PLL output, or will the phase have a transient before it hits steady state?
Phase adjustment and phase resync cannot be used at the same time.
Phase resync ensures that every time you lock to a certain frequency, the output phase will also be the time.
Phase adjust increases the output phase, after a write to R0, relative to the current phase. There is a very short transient effect as the phase steps forward by the set amount (in R1) of degrees.
