Unless you use some sort of "time to digital" converter. There's some ASICs out there that do this, and I've seen CPLDs programmed to do it. The new fancy oscilloscopes from,e.g., Tektronix have this so that you can measure jitter to finer resolution than the 20Gs/s sample rate. Seems one could also do a similar Time-to-Digital thing by using the old vernier counter scheme.. take your 5MHz and create a slightly offset version (4.9,5.1, or 5.01, etc.) by dividing and mixing and hook it up to a second counter.
