Thanks! the spec requires that the resolution to be 500ps, but does not specify the range of pulse widths. Moreover, I also need to measure the transition time of a digital signal (not pulse). I plan to input the signal to two comparators with pre-set start and stop thresholds to trigger and...

Thanks for the input! But What I need to measure is the width of arbitrary signal. Moreover, I also need to measure the signal transition time. How can a frequency divider be useful in this scenario?

Hi, I am designing a board-level circuit to measure pulse width, in which I need a high-precision timer. I want to use a high-speed counter to implement the timer. Since the timer requires an accuracy of 500ps, this implies that the clock to the counter has to run at a frequency of 2GHz...
