External Oscillator Allowed ?

Question asked by ChrisNielsen on Jun 5, 2013

I need to maintain tight ppm control over the main input high-speed clock source so I want to use an oscillator, not a crystal.  FXOSC on the Vybrid tower board uses a 24.000 crystal (the load caps and pcb stray cap cause too many variables for my application).

 

Is it possible to use a 24.000 MHz oscillator as the main input clock source?

 

The datasheet is unclear on this point.  It is also unclear what I/O voltages are allowed if an oscillator is supported.  Has any testing been done with an external oscillator?

 

Thanks, Chris
