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.
