If you re-read my first response you will see that I didn't either.. there was no reason to use a 100 MHz clock with a 16 MHz control... Until the OP added the TDR call Then I knew exactly what he was after and the reason for my suggestion about the AD9851... 5.5 nS @ 180 MHz and with an NCO you specify where the marker is.. I just wonder how he plans to profile a cable with a discontinuity that is 'normal'... Make a great lineman's tool for finding open/shorted cables though.

This has all moved on a bit while I slept. Thanks for all the ideas & help, as this project is still in the dream stage I have not finalized on specific components & methods yet but on Docedison comments I did search further and found a faster device (74VHC161 @ 183MHz) but as it's surface mount this means a custom PCB that I was hoping to avoid for now but this may be the way to go in the end.
The thing would be used to find breaks in camera Triax cables.
Don't PM me for help as I will ignore it.
