Phase noise - Analog Clock Synthesizer - AD9548

Hello,

I'd like to compare phase noise performances of different clock synthesizer but I do not know how to proceed: Analog datasheet gives you "Additive Phase noise" curves for different conditions of xtal, Loop BW,input and output frequencies... while Silicon Labs for example gives you "Phase Noise" curves at given input/output frequencies...

How would you compare chips and to know which one has the best performance?

(need a 292MHz output from a 10 Mhz input)

Thanks for your help,

YH.
