The 4HF212500Z3AACTGI crystal oscillator is powered by two quartz piezoelectric crystals, each of which is energized by an alternating current (AC) signal. This AC signal is provided by an excitation circuit which is composed of a transformer, a variable capacitor, and a resistor. The quartz crystals generate an AC electric field which is utilized by the excitation circuit to generate a precise frequency.

The crystals respond to the alternating current, creating a resonance frequency that is size-dependent. The surface area, thickness, and electrical resistance of the quartz crystal determine the frequency of resonance. The excitation circuit supplies a continuous alternating current of the same frequency as the quartz crystal, causing it to vibrate at that frequency.
