Working Principle

The 445A23C24M00000 consists of a quartz crystal and a resonator that form a feedback loop. The crystal oscillates at a specific frequency when a voltage is applied. The frequency is determined by the size and shape of the crystal, which vibrates at a harmonic when electricity passes through it. The stability of the frequency is ensured by proper temperature compensation that is achieved by the use of a temperature-sensing device and a heating element in the oscillator.

As the frequency of oscillation changes with the external environment, the temperature-sensing device senses the shift in frequency and then instructs the heating element to make adjustments in temperature. This helps to maintain the frequency, as temperature affects the frequency of the crystal. The temperature-sensing device and heating elements, along with the crystal and resonator, create a closed loop that ensures high precision and accuracy in frequency references.
