I know, I know :) As I said, first I'm looking around the different
techniques, advantages, disadvantages... I would like to know if the ADC
approach has other advantages

My main current application is jitter measurement and characterization,
so a moderate rate could be enough (but the greater the rate, the
better, of course :) ), but I prefer in this case, higher precission
more than higher rate.

Of course :)
