"First you cannot measure audio related jitter with a 7G scope."
I said P-P total jitter, not audioband jitter. This is what is speced in the specsheet. Just because it specs 10psec, in a real system it can easily be 100psec.
"Second to get low jitter from an oscillator you need to throw away 3 terminal regulators."
I already use discrete regulators, only the best.
Regarding optical isolation, these conversions just add jitter. I get great results without it. We will see how much jitter my products have when JA makes his measurements. I've been doing this a while too.
