As this is a noninverting D flip-flop, you will of course need to add an inverting buffer. The characteristics of that buffer are mostly unimportant because they mostly don't affect the jitter at the FF's Q output. But it does mean routing the FF output to at least two destinations (the inverter, and your load), which means being watchful for plateaus on that waveform, which could cause increased jitter, or double-clocking. ------------------------------------------------------------------ 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
