After all, DC biasing with varicap diodes across crystals are used in phase locked loop circuitry (to do the phase locking). And phase locking is really only a slight pulling against the natural frequency of your electronic tuning fork. > I completely fail to see why you might be concerned about the oscillator > producing a frequency of say 100.000000 MHz or 100.000100 MHz on a computer. I'm not. The other guy posed a theoretical question, and I gave a supposed answer. Smack it harder, and it'll ring differently. I didn't say it was going to be a huge difference. Considering that quartz watches keep good time with diminishing battery power over many years, being warmed by your wrist, and chilled by the weather, I wouldn't think you'd get a significant change in BIOS clock frequency depending on the BIOS battery, if it was designed to cope well with battery changes, unless it was deliberately designed to go goofy with significant battery charge drop. And, yes I am well aware of using crystal ovens for greater clock accuracy, in precision equipment. But I'd only seen them make a few Hertz difference in a 4.43 megahertz oscillator. -- tim@localhost ~]$ uname -rsvp Linux 3.19.5-100.fc20.i686 #1 SMP Mon Apr 20 20:28:39 UTC 2015 i686 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists.
