Introduction to Crystals: Q 27,120-JXS21-8-10/15-T1-FU-WA-LF

Crystals are an essential component in many electronic circuits, as they are used in oscillators, filters, and amplifiers to control the behavior of the circuit. The particular crystal Q 27,120-JXS21-8-10/15-T1-FU-WA-LF is an example of a quartz crystal, which is the most common type of crystal used in electronics. This article will discuss the application fields and working principles of Q 27,120-JXS21-8-10/15-T1-FU-WA-LF.

Application Fields of Q 27,120-JXS21-8-10/15-T1-FU-WA-LF

Q 27,120-JXS21-8-10/15-T1-FU-WA-LF is a cut crystal, with a center frequency of 27.120 MHz and a tolerance of ±10/15 ppm. It is ideal for frequency control in circuits that operate in the HF and VHF range, including signal and frequency synthesis in communication, broadcast, and test equipment. It is also suitable for use in FM transceivers, amateur radio, and digital signal processing systems.

Working Principle of Q 27,120-JXS21-8-10/15-T1-FU-WA-LF

Q 27,120-JXS21-8-10/15-T1-FU-WA-LF is a quartz crystal, which means that it is made from quartz. When an alternating electric field is applied to the crystal, it vibrates, creating oscillations of a precise frequency. These oscillations are known as the resonant frequency, which can be accurately tuned by shaping the quartz into a specific geometry. This makes quartz crystals ideal for use in oscillators, where their precise frequency determines the frequency of the output signal.In order to understand how a quartz crystal works, it is useful to look at its structure in a bit more detail. Quartz is composed of two layers of atoms: a crystalline top layer, composed of silicon and oxygen atoms, and a bottom layer composed of sodium and chloride atoms. When an alternating electric field is applied to the quartz crystal, these two layers vibrate at different frequencies. The difference between these two frequencies is known as the overtone frequency, and this frequency is what allows for precise frequency control.The frequency of the output signal is determined by the overtone frequency of the crystal, as well as the load capacitance applied to the crystal. The load capacitance must be carefully chosen in order to ensure that the output frequency is accurate. If the load capacitance is too high, the output frequency will be too low, and vice versa.Finally, it is important to note that Q 27,120-JXS21-8-10/15-T1-FU-WA-LF is also temperature sensitive. The frequency of the output signal can vary with changes in temperature, and therefore it is important to use temperature compensation components in order to ensure accuracy.

Conclusion

In conclusion, Q 27,120-JXS21-8-10/15-T1-FU-WA-LF is an ideal choice for applications that require precise frequency control in the HF to VHF range, including FM transceivers, amateur radio, and digital signal processing systems. It is a quartz crystal with a resonant frequency that can be precisely tuned by shaping the quartz into a specific geometry, but it also has to be used with temperature compensation components in order to ensure accuracy. Understanding the application fields and working principles of this crystal will help in its successful implementation in circuits.
