That is conceivable, depending on what spectrum the
noise has, (as Mr. Larkin mentioned), and many more
specifics than you have related.
Oh yeah- what exactly are those "many more specifics"- give us a rundown..
Incoming frequency
range, your ADC ENOB (in a decent eval setup),
and what spectrum processing is done to the samples
(or your whole phase noise requirement) should all
influence the design of that patch.
Patch? Patch? Hmmm- never have heard anyone refer to improving sampling
clock phase noise as a "patch".
That approach can be difficult or impossible to pull off,
or more costly than the system approach. (More later.)
Wouldn't that "patch" be the system approach? You really are a
windbag....you have to pretty dumb to think people don't see you are
total fake , fraud, generalist moron with no working knowledge whatsoever.
It's like other noise problems. You can use a PLL
as a filter, but it can add its own noise. Whether
the result is better depends on what got filtered
out and what got added.
hey everybody- read that non-informational crock of sh_t- is that a bs
dodge or what?
The approach I have seen work reliably is: Start
with a sufficiently pure source.
Oooh- well that makes it easy doesn't it- especially when you have an
unlimited government budget...the OP asked about approaches to improving
the phase noise of an existing source- and not a bunch of bs about
identifying a new one.
Distribute it with
careful attention to analog signaling issues.
People who know what they're doing don't have issues- why don't
enumerate some of those "signaling issues"- what are they?- what are the
most common ones?
Process
it with the same care.
Process it with care? Like what are you talking about here?
Do not think of it as a mere
"digital" signal, intact if 1's and 0's get through,
unless precise clock edge placement is immaterial.
Sounds like you're scolding the OP for your flawed approach. And this
crap about "precise clock edge placement is immaterial" just makes no
sense in a discussion about jitter-HAHAHAHAHAHAHAA- you do know that
A/D's sample on a clock edge, right? You know this don't you? You think
it integrates the waveform or something and sample jitter is an analog
average thing or something? Hey, if you don't know what you're talking
then maybe you should just shut the hell up, huh? Think that will work?
