I have phase noise data in [dBc/Hz] on a number of candidate clocks. I need to convert that into time jitter in a certain sample period. For example, I need to find the rms time jitter during a 10 millisecond sample period. I do not know how to do that!
I can find all sorts of programs out there to convert phase noise into rms time jitter with an infinite sample period, such as at wenzel or raltron's website. But, for a 10 mS sample period, obviously the lower frequency offset phase noise terms can be reduced in the calculation. Phase noise at 100 Hz offset, for instance, is not going to cause that much time jitter if I only look at the clock for a 10 mS sample period of time!
Anyone know of a spread sheet to calculate, or a correction factor to the phase noise data to input into the standard spread sheets?
Thanx
