most spectrum analyzers simply measure the power spectral density of the phase noise, and integrated it to show rms jitter. On the average, it is an accurate calculation.
As for a free-run oscillator, the jitter accumulates over time. The wavescope calculates jitter in a certain time windows. My question is if I want to know the rms jitter of a oscillator in a time range of ,maybe 4us , then what the is the frequency range for the integral of phase noise in reponse. (mainly, the lower limit of (...)
See equation for rms Period Jitter in attached figure. How to derive this equation ? Especially, how is sin() term from ?
In a phase-modulation scheme,rms phase error is very critical,it should be less than 2deg in most cases. This rms phase error directly relates to in-loop phase noise of pll output. while working with PLL frequency synthesizer, we come across two formulae to calculate (...)

When I simulated the phase noise of a ring oscillator based VCO using Spectre pnoise analysis, I found the rms accumulated jitter increasing with increasing the maximum number of sidebands. And the dominant noise contributor was the induced gate noise of some swtiched off units (Vds = 0) in (...)
Hello See this topic The Designer's Guide Community Forum - rms noise value calculation
In a CW carrier, the time jitter is figured out by integrating the phase noise, thereby converting it to pk-pk or rms time jitter. If one is deliberately FM modulating a carrier, then that FM modulation will easily dominate over the phase noise effect. So all you have to do is analyze the fm modualtion (...)
In general it will depend on the application but good tests include: - minimum load for stability - phase margin - gain and GBW - slew rate OR settling time to a specific level and accuracy - input common range - PSRR - rms noise Let us know if you need specific ideas
PLL phase Error rms = 107 x √ Loop_Bw x 10^(phase_noise / 20)

I have phase noise data in 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 (...)
question about pll noise ,thanks we have designed a pll,with nearly 4ps rms jitter with OSC measured. but with the Spectrum Analyzer ,the phase noise has the different value in the different frequency point . we want to know the different of the rms jitter and phase noise: (...)
I have rms jitter specification for a pll. what actually this refers to? Is this random jitter? If we do the phase noise simulation and calculate jitter value, what jitter we get?
If you know the spectrum of phase noise, you can get the rms jitter by integration. In the website of ADI, you can find some papers about how to integrate, e.x. AN-756.
rms phase Error to PN (phase noise in dBc)
how to convert phase noise to jitter(rms)?
I don't think you are able to generate an eye diagram from a clock signal (1010). The eye diagram is generated from a PRBS signal such as PRBS7 or PRBS23, etc.. For a clock signal the important parameters are rise/fall time, rms jitter (phase noise), Vout_pp vs. Frequency.
Longly we believe: ΔTabs,rms=(2π/To)? *lim∑Φ?n,j / N (1) then in Razavi's book IC in optical circuits' P28, it will becomes: ΔTabs,rms=(2π/To)? lim∫Φ?n(t)dt / T (2) then by Parceval's law: ΔTabs,rms= (2π/To)?∫SΦ(f)df ; (3) Therefore, we (...)
