Thanks to everyone for all the great replies.  I figured that the 10 MHz
output would have a fair bit of jitter/phase noise, but I figured I could
use something like a SiLabs Si5317 to clean it up, as per this app note:


Page 4 of the app note says it "*can accept a noisy reference clock at any
frequency from 1 to 710 MHz and provide two ultra-low jitter (0.3 ps rms,
12 kHz to 20 MHz) output clocks at the same frequency.*"  Thats seems
decent to me, but I'm a novice at this.  Anyone have any thoughts, or
caveats on this plan?
