Crystals: CM309E7372800BCAT Application Field and Working Principle

Crystals are important components used to convert electrical energy into stable mechanical vibrations of a precise frequency. These vibrations are typically referred to as oscillations and are used to control the frequency of electronic circuits in consumer and industrial applications. Crystal oscillators are widely used in consumer electronic products such as cell phones, personal computers, clock radios, and quartz watches. They are also used in precision industrial instruments such as temperature controllers and process monitors. Here, we discuss the application field and working principle of the CM309E7372800BCAT crystal oscillator.

Application Field

The CM309E7372800BCAT crystal oscillator module has a crystal frequency of 7.372800 ~ 7.733400 MHz and is suitable for use in Frequency Synthesizers, Radio Links, receivers/transmitters, and industrial remote controls. It exhibits excellent frequency stability and low-noise characteristics, making it ideal for these applications. In addition, its low cost and small size make it an ideal choice for applications in budget desktop and laptop computers, industrial control equipment, communication base stations, and other consumer electronic equipment.

Working Principle

The working principle of the CM309E7372800BCAT crystal oscillator module is based on the process of mechanical resonance. A quartz crystal is composed of a thin slice of quartz that is cut at an angle and bonded to two metal plates. When a voltage is applied to the two plates, the crystal begins to vibrate at its resonant frequency. This frequency is determined by the size, shape and orientation of the slice of quartz, and is very stable, with little variation over time. The vibrations are then amplified and used to control the frequency of the electronics in the system.

The CM309E7372800BCAT crystal oscillator is a quartz crystal resonator based on a piezoelectric oscillator circuit topology. A quartz crystal is placed between a pair of electrodes and when a voltage is applied to the crystal, the piezoelectric material inside the crystal produces mechanical vibrations at its resonant frequency. The vibrations are then amplified and used to generate the desired frequency. This allows for the oscillator to produce a frequency that is very stable, with little variation over time.

Conclusion

The CM309E7372800BCAT crystal oscillator module is a great choice for applications in Frequency Synthesizers, Radio Links, receivers/transmitters, and industrial remote controls. Its low cost and small size make it an ideal choice for budget desktop and laptop computers, industrial control equipment, communication base stations, and other consumer electronic equipment. The working principle of the module is based on the process of mechanical resonance, where the quartz crystal produces mechanical vibrations at its resonant frequency when a voltage is applied to the two plates, and these vibrations are then amplified and used to control the frequency of the electronics in the system.
