Crystals: 445A22S12M00000 application field and working principle

Crystals are a naturally occurring solid material consisting of to atoms, ions, or molecules, joined in an organized lattice arrangement that extends in all three spatial dimensions. They are used in many different applications, from watches and clocks to radio transmitters and receivers.The 445A22S12M00000 crystal is a precision quartz crystal used primarily as an oscillator. Oscillators are devices used to create alternating or periodic electric pulses or signals, based on the properties of the crystal. The 445A22S12M00000 crystal is an industry-grade precision oscillator suitable for laboratory applications, where accuracy and reliability is paramount.The 445A22S12M00000 quartz crystal consists of a thin disc of quartz crystal, cut precisely along its crystalline plane, so it produces a clean, smooth oscillation. The crystal is hosted in a ceramic package and connected to two silver plated electrodes. Two wires (drain and source) are connected to the electrodes, through which the oscillator current flows. This current produces a frequency-dependent voltage across the crystal, which oscillates at a controlled frequency and maintains a stable, accurate frequency.The 445A22S12M00000 crystal can be used as a high-precision frequency source, such as in radio receivers and transmitters, or as a timing element, such as in clocks, watches, computers and microprocessors. The accuracy of the oscillator can be adjusted using the oscillator frequency, the application circuit, the temperature of the circuit, and the environment.The frequency of the oscillator is determined primarily by the size of the crystal, and is usually specified in megahertz (MHz). The 445A22S12M00000 crystal has a frequency range of 10.24 — 10.25 MHz. This frequency range can be adjusted by manipulating the electrode voltage and current. The frequency can also be adjusted manually by inserting a small silver disc into an access hole in the oscillator housing, which alters the frequency by changing the size of the quartz crystal.When the electrodes are connected to the oscillator, a sharp and stable sine wave is produced. The frequency of the sine wave is determined mainly by the size of the crystal, but can also be changed using the circuit components, such as resistors and capacitors. The generated frequency can be measured using an oscilloscope.The 445A22S12M00000 crystal oscillator can be used both as a high-precision frequency source and as a timing element. It is stable and accurate, and is used in a variety of applications, such as watches, clocks, radios, and computers. The frequency of the oscillator can be adjusted by manipulating the electrode voltage and current, or by inserting a small silver disc into an access hole in the oscillator housing. The frequency is primarily determined by the size of the crystal, but can also be adjusted by using the circuit components.
