Hi Vikas, That's a coincidence! I stumbled upon your site a few days ago. Some feedback, as requested. On: http://referencedesigner.com/tutorials/si/si_02.php ...the figure is a little confusing to me. 1) The left hand boundary of Ts seems to be too far left. Surely the data has to reach closer to Vh before it can be considered "set up"? 2) Shouldn't the left hand boundary of Th be aligned with the right hand boundary of Ts? -- Colin http://signal-integrity-tips.com ------------------------------------------------------------------ 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 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
