hi All, normally when we look at the data sheets of a clock signal for the jitter number, they usually specify it a RMS jitter. i understand from the basics that , only random jitter is quantified as RMS. i am not sure why there is only random jitter in the clock. is the Deterministic component is negligible? in that case, using our EzJIT plus software, if i want to measure this spec of a the clock, what would be my measurement? is it ok, if i measure the TIE of the clock and take the RMS of the TIE trend? thanks, hari ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List technical documents are available at: http://www.si-list.net List archives are viewable at: //www.freelists.org/archives/si-list Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
