Crystals: ABM3B-12.1875MHZ-10-D4-T Application Field and Working Principle

Crystals are vital components in any electronic device, fulfilling the important role of providing timing and frequency reference to driving circuits. This article will walk through their application fields and working principle with the ABM3B-12.1875MHZ-10-D4-T crystal as an example.

Application Fields

Crystals are used in a variety of electronic devices, from computers, mobile phones, radio transmitters and receivers, to small television receivers and pocket calculators. They can work to produce watch clocks and quartz clocks, laser cavities and filters, and many other applications. The ABM3B-12.1875MHZ-10-D4-T crystal is particularly suited for timer, oscillator, microwave, and resonator applications due to its specification. It is used when long-term stability of frequency is required.

Working Principle

The ABM3B-12.1875MHZ-10-D4-T crystal is a tiny quartz crystal-based oscillator. It is made up of two identical plates of quartz that have been cut in the shape of a rectangular prism and mounted along the main axis on either side of a copper-zinc alloy post. The crystal is placed under tension, or “stress”, which causes the crystal to vibrate at a precise frequency. The vibration of the crystal is transmitted through the copper-zinc alloy post and picked up by a coil of copper wire, which further amplifies the signal. The crystal is sensitive to both temperature and stress. When the crystal is subjected to temperature changes it produces distortions in the output signal frequency. This is known as temperature tuning. The ABM3B-12.1875MHZ-10-D4-T crystal is also sensitive to stress, and when subjected to mechanical pressure its frequency increases. This is known as frequency tuning. The ABM3B-12.1875MHZ-10-D4-T crystal is extremely accurate and provides a highly stable frequency reference for its applications. With its wide range of temperature and pressure tuning, it provides a highly reliable frequency reference even under extreme conditions.

Conclusion

The ABM3B-12.1875MHZ-10-D4-T crystal is a valuable component for a wide range of applications. It is a quartz crystal-based oscillator, consisting of two identical plates of quartz mounted on a copper-zinc alloy post and placed under tension. It functions as both a temperature tuner and frequency tuner, providing a highly stable, accurate reference to its various application fields.
