I dont think the important thing is the Schmitt Trigger, but rather the square wave. But putting multiple '04 inverters in sequence was a well known method to shapen flanks, and I have always understood that as the reason for using three in the xtal clock generator setup. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [email protected] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- [email protected] -- To unsubscribe send an email to [email protected] To unsubscribe, go to and follow the instructions there.
