That sounds like they are running the external signal through a synchronizer
and then doing all the logic on the system clock.

That is actually a particularly bad way of doing it, because the

I've got a teensy3.1 hooked up to a 33120 function generator (not

The period is in "ticks" of the 48 MHz clock, so my thinking is that if
I hook up a good 1pps, what I'm really measuring is the frequency of the
