Crystal Testing Circuit



Crystal Testing Circuit 


Quick oscillator circuit, powering a 16MHz crystal. 





Powered by 2.4vDC:




Hex inverter pinout:




Breadboard circuit:



16MHz on the frequency meter:

It worked dead on with a 16MHz crystal, ok with slightly higher frequency crystals but was unstable at lower frequencies. Just need to adjust capacitors and resistors.

This uses a 74hc04 hex inverter IC chip.
