there is rfmd controller software you can download to drive it. Start with that--usually the software will not let you input invalid register values. If you are using your own controller....it is really easy to get the register values wrong and the unit will simply not work. Also, there are sometimes combinations of frequencies that will never work, and need to be skipped over.

Since you have a single frequency, you can use 10 MHz or 1 MHz at the PFD detector. If using 10 MHz, you obviously need to set the vco divider to 224, etc. Make sure the external 10 MHz is a big enough signal to drive the chip.
