How do you achieve phase synchronization from different frequency sources?

How do you achieve phase synchronization from different frequency sources?

  • On behalf of Travis Collins:
    In regards to using different frequency sources, like an external LO, the RF PLL synchronization offered in the ADRV9009 and ADRV9009-SOM applies in this case as well. Without the RF PLL synchronization, when using external LOs there is a random 180 shift that can appear between parts due to the K dividers which are always applied to the external LO source. For the ADRV9009-SOM we do provide external LO pins for both transceivers independently, which was not available on previous SOMs.
