The output sign in the crystal oscillator is actually a sine wave getting a frequency set with the crystal's resonance frequency. When an electrical voltage is applied to a quartz crystal, it physically deforms or vibrates. Conversely, when the crystal is mechanically stressed, it generates an electrical voltage.
