1Mhz-pierce-oscillators

  
The circuit is an inverter set up as a linear amplifier. Adding the· crystal and capacitors to the feedback path, we turn the amplifier into an oscillator and force it to oscillate at, or least very near, the crystal`s resonant frequency. Trimmer capacitor C2 adjusts the actual operating frequency of the circuit.

The crystal should be a parallel-resonant type; maximum frequency will depend partly on supply voltage, but it should be possible to go to at least 1 MHz.
