Crystal Oscillator Schematic

The crystal oscillator circuit sustains oscillation by taking a voltage signal from the quartz resonator, amplifying it, and feeding it back to the resonator. The rate of expansion and contraction of the quartz is the resonant frequency, and is determined by the cut and size of the crystal.

How do you make a crystal oscillator circuit?

The one i'm using is a ceramic 455 kilohertz oscillator now this is going to be attached to the base

What's inside a crystal oscillator?

Crystal oscillators use a mechanically resonant, piezoelectric circuit element in the feedback loop of an amplifying device. This element is usually a quartz crystal, hence the name. Certain crystals, and electrically polarized ceramics, exhibit a property called piezoelectricity.
