Crystals are materials composed of atoms arranged in a three-dimensional, repeating, ordered pattern. In general, crystals exhibit a wide range of physical, chemical, and special optical properties that can be exploited for a variety of applications. Examples include semiconductor devices, optical components, piezoelectric actuators, high power laser components, acoustic devices, and crystal filters. This article will focus on 7A20000012 application field and working principle.
7A20000012 is a type of crystal resonator and is used most commonly for clocks, frequency references, and timing in digital systems. It is constructed using a thin-film piezoelectric material and electrodes and is designed to operate at 28.8 MHz. The main advantage of this crystal resonator is its low power consumption, making it a popular choice in battery-powered applications. The crystal itself is packaged in a small, hermetically sealed package and is usually available with a selection of output pins and connection options.
The working principle of the 7A20000012 crystal is simple. When voltage is applied to its electrodes, an electric field is created across the crystal, which causes the molecules in the crystal to vibrate. These vibrations create an acoustic wave that is frequency-dependent on the crystal’s thickness and shape. By controlling the voltage and the length and width of the crystal, the resonant frequencies can be controlled accurately. For example, a 7A20000012 crystal can be tuned to a precise frequency to create a precise clock or reference, making it ideal for a wide range of applications.
In terms of application field, 7A20000012 crystal resonators can be used in a wide range of applications. Most commonly, they are used in clocks, for frequency references, and for timings in digital systems. For example, they are often used in digital systems for precise timing control and synchronization. They are also ideal for use in frequency divider circuits and for generating precise signals for radio transmitters. Additionally, they can be used in acoustic devices, such as loudspeakers and microphones.
In summary, 7A20000012 crystal resonators are a type of crystal used in a variety of applications. They are designed to operate at 28.8 MHz and have extremely low power consumption. The working principle of the crystal is simple; when voltage is applied to the electrodes, an electric field is created which causes the molecules in the crystal to vibrate and create an acoustic wave with a frequency dependent on the crystal’s length and width. In terms of application field, 7A20000012 crystal resonators can be used in clocks, for frequency references, for timings in digital systems, for frequency divider circuits, for generating precise signals for radio transmitters, and for acoustic devices. As such, 7A20000012 crystal resonators are a widely used and versatile component for a range of applications.
