Clock generator

[Anon_LG]

Please could someone show me a circuit diagram of a simple clock generator circuit that incorporates a crystal oscillator in the resonant circuit, does not rely on any capacitors to control the frequency and has an output frequency of around 1 Mhz. The specific frequency does not matter.

Look here.
You may need additional capacitors (see here) to get the oscillator running stable. These capacitors will influence the frequency by a small amount. The fundamental frequency, however, is defined by the quartz.

There's a good general document that covers the standard single-gate Pierce oscillator that can be built using CMOS or 74HC gates at http://www.crystek.com/documents/appnotes/Pierce-GateIntroduction.pdf

Thankyou Harald Kapp and KrisBlueNZ. I will have to read the full document you have provided only when I am sure my circuit, in which I will be using the clock generator, will function.

You can get a 1MHz oscillator in a single package as well.
