What does the crystal oscillator rely on to start oscillation?

Simply put, the driving force behind the oscillation of a crystal oscillator is electricity. We need to place a crystal oscillator in a complete circuit and power the circuit to generate a loop current. From then on, the crystal oscillator begins to "beat" steadily and rhythmically.

How to layout the crystal oscillator on the PCB

The equivalent circuit of a crystal shows a series RLC circuit, representing the mechanical vibration of the crystal, in parallel with a capacitor representing the electrical connection to the crystal, and the crystal oscillator operates towards series resonance.
