    Hi. 
    Thanks.
    As to the integration limits, i guess you are saying that the clock frequency (half of it) defines the upper limit, right? if user inputs a higher upper freq, it will get ignored?
    by the way, the unit of phase noise is wrong in DPOJET, it's lablled by dBc/sqrt(Hz) instead of dBc/Hz. 

    regards

    I'd like to know more about how do you calculate the phase noise in DPOJET tool box? is it FFT of TIE jitter sequence?

    and if my input clock is 1Mhz, how to set noise integration limits (upper/lower frequency)? shall i set the upper frequency = 1MHz/2?
    is it the integrated bandwidth in which total TIE jitter power put in?

    thanks
