HMC4069 phase noise

Hello,

What is HMC4069's noise @ +10 Hz, ( Pll locked @ 100 MHz from 10 MHz reference)?

Our reference is -145 dBc/Hz @ +10 Hz, loop filter is 200 Hz width (active filter using THS4031).

We are measuring -110 dBc/Hz, while our simulation on simpll predict -120 dBc/Hz.

Thank you for your help.
