At 64MHz I couldn't ignore the jitter. I don't remember what cap configuration I used, but it took me quite a while through trial and error to come up with an acceptable transition (regret not having documented work on that project - of course it got put on the shelf and I moved on to something else and undid all my prototyping boards).
