Crystals

Crystals, in their natural form, are some of the oldest known materials used in electronics. Crystals are used in a variety of electronic applications, including watches, wall clocks, mobile phones, and computers. In order to understand the application field and working principle of 402F27012IKT crystal, it is important to first understand how crystals work.

Clocks and Oscillators

Crystal oscillators are the most common use for crystals in the modern world. A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonant frequency of a vibrating crystal of at least a few tens of kilohertz to create an electrical signal with a very precise frequency. These circuits are often used to create precision time base for radio transmitters and receivers.

The crystal oscillator circut includes an amplifier (gate), an inverter, and the crystal itself. The output signal from the amplifier is then connected to an inverter and then to the crystal. As the crystal vibrates, it produces electrical signals that oscillate at the resonant frequency of the crystal. The vibration of the crystal is controlled by a feedback signal that is generated by the inverter and amplifer.

The frequency of the oscillation signal is determined by the physical characteristics of the crystal, including its size, shape, and material, as well as the type of electrical circuit it is connected to.
