ATS20B

Crystals are essential components in electronic systems. They are used to maintain precise timing in oscillators, receivers and transmitters, and to realize communication by radio waves. The ATS20B piezo-resistive quartz crystal from Murata Manufacturing is used in radio frequency (RF), timing and telecommunications applications due to its excellent performance over a wide range of frequencies and temperature ranges. This article provides an overview of the ATS20B\'s application fields and working principles.

Application Fields

The ATS20B quartz crystal is used in a variety of applications, including:

• Automotive, medical, and mobile phone applications
• Wireless communication systems
• USB, camera and GPS applications
• Wireless communication devices such as Bluetooth and Wi-Fi devices
• Industrial, energy management, and military electronics.

Working Principle

The ATS20B piezo-resistive quartz crystal consists of a quartz crystal and an electrode structure. When an electric field is applied to the electrodes, the quartz crystal produces a mechanical vibration at a fixed frequency. This vibration is referred to as the “resonance frequency”. The resonance frequency of quartz crystals is generally determined by their cut angle, size, temperature and other factors. By applying a voltage to the terminal, the resonance frequency can be changed, so that the frequency can be used as a means of controlling RF circuits.

The ATS20B also has a piezo-resistive structure, which allows a voltage or resistance to be applied through the electrodes to sense crystal movement. This structure improves stability over a wide temperature range of -55°C to +125°C. It also helps to adjust the frequency over a wide range of frequencies (2MHz to 50MHz).

Conclusion

The ATS20B piezo-resistive quartz crystal from Murata Manufacturing is used for a wide range of applications, including automotive, medical, military, and wireless communication devices. It has a piezo-resistive structure that enables frequency adjustment over a wide temperature range and frequency range. The ATS20B is an excellent choice for applications that require precision frequency control.
