Hi
Roughly speaking, if you have a 10 MHz clock driving a timer and the pin
latches data
from that timer, you get 100 ns “buckets and +/- 100 ns “jitter”. You can find
MCU’s that
will do this for < $1. If you go crazy, you can spend < $10 and still get a
very fancy MCU
on a board with all

We're most certainly getting off topic, but the
