Hi all, I have a little confusion on PPM vs frequency of Crystal Oscillators.How important is the term 'ppm' than frequency.Why all the datasheets have both units,ppm and Hz.Please clarify,Also how much important is the value of ppm on the Signal integrity side,if any.Thanks for your time. -- bala ------------------------------------------------------------------ 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
