Re: 184 Time Mark Gen. - 2nS & 5nS not working

I put a 4.7pF MLCC in series with C11 and got the oscillator tuned. It is cycling between 10.000005MHz and 9.999994MHz. How bout that :) It was trial & error, it's kinda strange, I tried 2.5pF and then 5.6pF and neither one would increase the frequency much at all. I tried the 4.7pF last and it worked perfectly. C11 is in the middle of it's adjustment range now. Overkill? Yep.
