Hello,  Can you help recommend the best part?  

I'm looking for a Clock Generator that can support 128MHz hitless switch-over in a non-SONET application.

The datasheets on AD9557, AD9548, HMC7044, and other parts  do not have much detail on hitless switching.  

How closely would the REFA and REFB need to be? 

Is there an ADI tutorial on hit-less switching?
