Hm, there's beauty to that, but also there's beauty in not letting the
oscillator drift of indefinitely after you've locked once.
So, the classical fastlock at startup/loss of reference lock, and then
increasingly reduced loop filter bandwidth would probably be even
better.
But that means relativel
Hi,
I didn't see the screenshots (not posted to the list ?)
But if absolute precision of the clock doesn't matter, you might be better
off disabling the servo loop once it's "close enough". That will require
fpga modifications to expose the refpll control though.
Actually I think this would be a
