Hi All,

Been looking for what (if any)  difference there is in output between
25Mhz and 27Mhz Xtal?  Best I can find is that 25Mhz might go lower
2.5khz than 27Mhz -3.25khz.

there are no differences. you can either trim the frequency at the crystal with a trimmer or just make software adjustments.

Thanks Dana,

I have found nothing in Si5351 data-sheet about what can/cannot be done other than no more than two different outputs above 112.5, max  freq 200Mhz, min freq 2.5khz.  Xtal between 25 and 27 Mhz.

Not tried the Clock Builder as I only have Linux. I don't usually bother trying Wine.
