Title: Divider SSB phase noise
Post by kevinm on Jan 21^st, 2008, 6:38am

Hi,
I've a question about simulating divider phase noise:

After running a pnoise analysis (noise type =jitter) I can plot the noise voltage PSD at the threshold crossing time

pow(getData("out" ?result "pnoise_pmjitter") 2)

Is this SSB noise?
Or do I need to divide this noise by a factor of 2 before I can calculate the divider's SSB phase noise
using equations (1) and (5) in the doc "Simulating the Phase noise Contribution of the divider in a phase lock loop"

thanks for your help,
Kevin.
