pll jitter in papers - not specified which jitter it is

pll jitter in papers

Hi guys,
as well known, there are 3 commonly used jitter metrics: cycle to cycle jitter, period jitter and time interval error.
I have read a lot of paper about PLL. Most of them give measured jitter of PLL clock. But, few of them specify what kind of jitter it is.
I think it doesn't make sense by talking bout jitter and don't specify what jitter it is.

How do you think of that?

I think in that case they are refering to the peak to peak jitter. Otherwise they mension the kind of jitter.

I think it's not a problem of peak to peak jitter or rms jitter. All of 3 metrics can be described as peak to peak value of RMS value. One should clarify that it's cycle to cycle jitter, period jitter or TIE.
