The Teensy 3 can be programmed using the Arduino software. It's just a
better Arduino, that's it.
But you say you have a PI. Why not use that? send your final RF to a
zero crossing detector then to a counter in the PI.
I expect the PI does not have a counter, nor I would know how to set it
up.
Marullo looks like you have a solution. Even a choice of displays.
Paul and others,
thanks but that was not exactly what I was searching for. You did give
me very good suggestions but my problem is a little more subtle.
I just need the simplest chip incarnation that would provide me with

Welcome to the group.

Hi all,
just subscribed, I would like a quick advice on a 10MHz reference for
calibrating my instruments and for fun. In particular, I would like to
know if you could give me advice on EFRATOM FRS-A,FRS-C, DATUM LPRO-101,
Thunderbolt and such.
I would prefer a GPSDO (like the Thunderbolt),
Thanks a lot to all for your quick answer.
Rubinium should be good for my needs, but buying it surplus makes me
think I could get something very used (and abused) and it does not have
the self correcting thing thunderbolt has.
GPSDO gives me also the time, maybe with a supercool LCD display.
