How to connect a crystal oscillator to generate Square wave

Posted on Feb 7, 2014

If you want a 1MHz square wave, I would suggest using a higher frequency crystal and dividing it down, for two reasons: (1) 4MHz crystals are apt to be cheaper and easier to find than 1MHz ones; (2) Getting a 50. 0000% duty cycle from a crystal is a bit tricky; by contrast, if one converts the signal from a crystal into a pulse wave (just pass it through an inverter or two) and

divides that down, the resulting wave will "naturally" have a perfect 50% duty cycle. supercat Nov 19 `12 at 16:52
