I just installed a couple of good size caps on the DC/DC Converter and now all the way to 1 us there is no apparent noise on the scope.

Also installed (by guessing) a 10k and a .47mf cap on the input as signal conditioning and it didn't seem to make any difference.

I still have the jitter but it has been reduced. I'm trying to figure out what values are needed for the RC Network to filter properly for my application. I will continue to search.
