Pardon my ignorance, but what is a bubbler? Is that  time-nut speak for a
frequency doubler of some sort? Guessing at a doubler  since you mention 
needing a 100 MHz output, and the CS2300 only has  a  6-75 MHz output range.

Just thinking aloud here...

IF  (big if ;) you are considering doubling, you might just as well use the 
 
ICS670-03.
Add a flip-flop between the FBCLK and FBIN to serve as an  external 
divide-by-two.
Then you can use the x5 and x10 settings to  give you an effective division 
factor
of 10 and 20 respectively. Which  in turn gives you 100 MHz output for that 
5 
Mhz 
or 10 MHz  input.

Fred
