Right, that makes sense. Although I suspect that there's a "spectrum" of contributions both from the individual VCOs and the common reference, without a clear dividingThe close in noise is from the COMMON reference, so there is nothing to cancel, it is perfect. It is the further out phase noise components which are not the same between the 2 PLLs, since those components are from the individual VCOs. These integrate out fairly quickly, and are much smaller anyway.
