Hello Gurus, Does the concept of Simultaneous Switching (SSO) apply only to single-ended signal or the differential pairs as well. In other words, do we only care (when designing the decoupling strategy) how many single-ended outputs are switching simultaneously or do we have to account for diff. pairs as well. regards Ibrahim Khan ------------------------------------------------------------------ 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 archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
