[time-nuts] Calculating phase jitter from phase noise - appnote by silabs
Moin, I just stumbled over a nice little summary how to calculate the jitter of a signal from its phase noise plot by silicon labs: http://www.silabs.com/Support%20Documents/TechnicalDocs/AN256.pdf Attila Kinali -- The trouble with you, Shev, is you don't say anything until you've saved up a whole truckload of damned heavy brick arguments and then you dump them all out and never look at the bleeding body mangled beneath the heap -- Tirin, The Dispossessed, U.

Hi Be very careful with all these phase noise to jitter conversions. They make some assumptions about the noise that are likely true, but may not be. The gotcha is that a normal noise measurement does not take phase data. Without the phase data you really can't properly do the reconstruction. You have to assume that it's random in the phase domain.

Hi, here is a very nice and easy to use online calculator for doing exactly this: _http://jittertime.com/resources/pncalc.shtml_ (http://jittertime.com/resources/pncalc.shtml) bye, Said In a message dated 5/11/2012 09:17:30 Pacific Daylight Time, li...@rtty.us writes: Hi Be very careful with all these phase noise to jitter conversions.
