Working Principle of 402F2501XIKT Crystal Oscillators

At the heart of every crystal oscillator is a quartz crystal, which consists of a piezoelectric material cut in the shape of a rectangular plate. When a voltage is applied to the crystal, it vibrates at a specific frequency. This frequency is determined by the physical characteristics of the crystal itself.The quartz crystal in the 402F2501XIKT crystal oscillators is connected to two elements that act as the feedback components. One element is a capacitor connected between the output and one of the crystal terminals, and the other is a resistor connected between the other terminal and ground. These components determine the oscillation frequency of the crystal, which is determined by the resonance frequency of the quartz crystal.The 402F2501XIKT crystal oscillator can be configured to operate in either the fundamental mode or the overtone mode. The fundamental mode utilizes the resonance frequency of the crystal, while the overtone mode utilizes higher order frequency multiples of the fundamental frequency.The crystal oscillator is usually connected to a circuit that amplifies and filters the signal from the crystal to generate the output signal. The characteristics of the amplifier and filter depend on the application and output frequency desired.
