ADF4108 configured as detector - not pll

Would like to use the mux out to use the ADF4108 as a detector only, so don't need the CP, or Refin.

I assume setting the CP to three-state (DB8 (F3) in the Function latch and Initialization maps (Fig 18 and 19 in Rev A datasheet).

- What should be done with the CP output, RSet and REFIN pins to minimize noise?

 

Thanks
