Working Principle:

The 402F480XXCAT crystal oscillator is a quartz crystal based oscillator that uses a quartz crystal as its frequency controlling element. The crystal oscillator works on the principle of piezoelectric effect. A piezoelectric crystal, when subjected to an alternating electric field alternately expands and contracts perpendicularly to the plane of the crystal. This physical movement creates a periodic mechanical strain in the crystal that generates an alternating electric field.

When an alternating electric field is applied to an AT-cut quartz crystal, the crystal starts vibrating at its natural frequency. This frequency is determined by its physical size and the mechanical load on the crystal. Then, the alternating electric field is converted into an alternating voltage, which is used as an output signal from the crystal oscillator.

The frequency of the output signal is determined by the frequency of the electric field and the mass of the quartz crystal. Therefore, the frequency of the output signal is highly accurate and stable due to the precise fabrication of the quartz crystal. The 402F480XXCAT crystal oscillator utilizes this principle to generate accurate and stable frequency output.
