Another option is to use a low pass filter to increase the transition times of
the signal to be timestamped and use a pipelined ADC to sample the filter
output.Perhaps something like the attached filter derived from:

May be effective in that it has near Gaussian response with relatively low out
of band SWR.

How much will dielectric absorption in the capacitor affect the
accuracy of the result with such a high conversion rate? I am used to
dealing with it on much longer time scales and higher resolutions.
