Wes:
All of that exists on just a single chip these days, it is possible to have an osc chip which is usable from 1Mhz-to-1Ghz and puts out an acceptable sine... .... or so my son informs me. I took his word for it... the world has began to pass me by ![]() John "Wes Stewart" wrote in message ...

I never dreamed anyone could be mistaken that someone was claiming that many osc's in a computer, but you never can tell about the CB'ers--they might think so! Here is a mess of stuff on clocks, osc's which are generally used in digital equip these days (and this is stuff I am used to, a decade old or better technology, probably two decades!): A mess indeed. ... it should be apparent mr. pierce is not here in (at least most) of this material: Well, he's he http://www.mtron.com/pdf/eng_notes.pdf (See Figure 8 and associated text.) http://www.statek.com/new/pdf/tn30.pdf http://www.statek.com/new/pdf/tn31.pdf Simple logic gate oscillator: http://www.it.lth.se/digp/PDF_files/oscillators.pdf Thanks for making my point! "A better oscillator using inverter gates is given in Figure 2." (This is a Pierce.) Design of op amp oscillators: http://focus.ti.com/lit/an/slyt164/slyt164.pdf Does not apply. Earlier I said, "All sine wave oscillators, LC or crystal, are basically the same circuit with the only variable being the location of the rf common point." These are not LC or crystal oscillators. The only place you might find one of these in a modern radio is in the sidetone oscillator. CMOS oscillator: http://www.ee.washington.edu/circuit...ASCIISCHEM_004 Tinker Toy Clock divider: http://www.ee.washington.edu/circuit...s/clockdiv.txt Not an oscillator. You too busy writing to actually look at your references? clock doubler: http://www.ee.washington.edu/circuit...ckdoubler.html Op cit. square wave to sine converter: http://www.ee.washington.edu/circuit...quare2sine.txt Op cit. pdf on digital oscillators: http://online.physics.uiuc.edu/cours..._TTL_Logic.pdf This is a college course?
