Crystals

Crystals are widely used in modern electronic systems, they are the building blocks of all electronic devices. They provide the required frequency and timing information and thus have become an indispensable component in modern communication and navigation equipment. The crystal oscillator is the most common, and allows even distribution of frequency or signal over a wide range, with high accuracy and stability. In this article, we will discuss the application field and working principle of one specific type of crystal oscillator, the Q 27,120-JXS21-10-10/10-FU-WA-LF.

Application Field

The Q 27,120-JXS21-10-10/10-FU-WA-LF crystal oscillator is a highly accurate and reliable time reference unit. It is specially designed for use in a variety of frequencies and applications. The oscillator is especially suitable for clock generation, crystal control of the oscillator, frequency synthesizer use, frequency capture, and phase-locked loop (PLL) designs. The crystal oscillator is also used for frequency precision and stability control, as well as for telecomm signals.

Working Principle

At the heart of the Q 27,120-JXS21-10-10/10-FU-WA-LF crystal oscillator is a quartz quartz crystal. The quartz crystal is like a spring that produces an orderly vibration when a voltage is applied. The crystal has two modes of vibration, the torsional mode and the shear mode. The torsional mode gives less stable frequency and is most often used in medium-frequency crystals, while the shear mode gives a more stable frequency. The crystal also distorts due to the mechanical stress created by the current running through it. This is called “piezoelectric” effect.

The crystal oscillator also includes a CMOS delay line, which is a device that allows an incoming signal to be delayed by a certain amount of time. This delay affects the overall frequency of the output signal. The oscillator also includes a clock oscillator circuit, which is a circuit that controls the frequency of the oscillator. The clock oscillator circuit generates the necessary voltage to power the crystal and controls the level of frequency.

In conclusion, the Q 27,120-JXS21-10-10/10-FU-WA-LF crystal oscillator is a highly accurate and reliable time reference unit with a variety of applications. The Q27,120-JXS21-10-10/10-FU-WA-LF is especially suitable for use in clock generation, crystal control of the oscillator, frequency synthesizer use, frequency capture, and phase-locked loop designs. Finally, the oscillator works by the quartz crystal and CMOS delay line creating the desired frequency, which is then controlled by the clock oscillator circuit.
