I believe your second counter (the one that starts on one edge and
stops on the other) will have trouble. It is unlikely you will get
your 14 ns resolution out of it.
Are you thinking to sync logic inside the device or
other problems? (not considering "defects" li

The analog TDC is a fine idea. Cheap, easy, and requires a few parts that are
not built into the micro controller. The simpl

Are you using the pll to obtain 72MHz (x9) for the clock?
Yes, the crystal oscillator is multiplied up to 72MHz which then
drives the timer. Even though the particular timer peripheral I
chose happens to be on the APB1 bu

Thank you very much, I will study it with interest,
it will be very helpul to see what you have done.

Coincidentally, my previous time-nut project was built around the
same chip. I built a simpl

It's mainly to learn something new.
For some reason I collected some Rb oscillators,
and I'd like to have a 10MHz absolute reference,
so I will try to discipline one of the Rb, and
later maybe an OCXO.
The proj
Hello, I've written few messages on this mailing
list, I'm an absolute beginner on timing science.
I've never introduced myself, so this is a sort
of introduction...
Although this has nothing to do with
arduino, reading the post by Chris Albertson
about an arduino-based GPSDO, I will share
what
