Jitter cacluation from phase noise??

Hello everyone,

Maybe many RF & IC designers must be suffer from jitter calculation from phase noise like me.

I read almost all the major documents in google(e.g. Jitter measurements using SpectreRF Application note)

However I can't find any explicit answer or solution about jitter calculation.

Can anybody help me understand the jitter calculation?

My question is simple.

How can I decide the phase noise integration range to calculate jitter?(with selecting noise type as jitter in pnoise)

In many papers, the range was selected 1kHz(10kHz)~10MHz. What's the reason?

In ADI's application note(for ADC), the range was selected 100~2*Fout(i.e. twice of sampling frequency)

Although there are many documents about it, I'm still confused.

Why the phase noise in high frequency is not integrated??

How can I select the low-frequency limit and high-frequency limit for RMS jitter calculation? 

Followings are other questions

1) in PSS simulation

-Output harmonics:Number of harmonics

If I am right, the number of harmonics means how many harmonics will be consisted in PSS analysis.

When smaller number used, more noise folded into low frequency. right?? If I'm wrong please point out.

2) in PNOISE simulation

-Output Frequency sweep range

I can't understand this parameter. Even in spectreRF manual, there's no explanation about this.

If I make a free running oscillator 100MHz, what frequency has to be stop frequency? 50MHz? 200MHz?

I selected start frequency to 1Hz

-Sidebands

Maximum sidebands determines the noise folding range

If one sets it 7, noise at higher frequency than 7th sideband will be folded into 1~7 sidebands. right?
