time. This timed-tuning ensures that the phase offsets between VCO/PLL
chains will remain constant after each re-tune. See notes below:
+- Phase synchronization with the UBX is only supported on the X3x0 Series
+- Phase synchronization with the SBX works on both N2x0 and X3x0 Series
- There is a random phase offset between any two frontends
- This phase offset is different for different LO frequencies
- This phase offset remains constant after retuning
- - Due to a divider, UBX phase offset will be randomly +/- 180 deg after re-tune on N200/N210.
- On X300/X310, phase sync with UBX fully works.
- This phase offset will drift over time due to thermal and other characteristics
- Periodic calibration will be necessary for phase-coherent applications
