[ntp:questions] Onboard Local Oscillator Change Improvements

[Eric.Jones]

Alternatively to Harlan's suggestions, there are a few DIY alternatives 
also if you are so inclined...

TAPR has a nice clock-generator kit with an ICS525 chip that can use an 
external GPS signal rather than a crystal:

And Cypress has evaluation kits using their new CY22180 very low jitter 
clock generator module, if you'd prefer a RYO design instead.
