Composition of the MP320B Crystal

The MP320B Crystal is a type of oscillator crystal with a broad frequency range, [1]. It is composed mainly of a series of quartz wafers assembled together in a special dielectric sheath, [2].The quartz is sandwiched between two forming electrodes,which are held in place by a shaped alloy frame. The quartz is then encapsulated in a sealed metal case.

Applicable Field of MP320B Crystal Oscillator

The MP320B Crystal oscillator is designed to be used in a variety of wireless applications, such as electronic telemeters, remote control systems, short-range communications systems, and hand-held transistor radios. Furthermore, this type of device is also used in many different types of electronic instrumentation, such as oscilloscopes, audio mixer consoles, and frequency synthesizers. Due to its excellent performance characteristics and stability, these crystals are particularly suitable for radio-transceiver applications, [3].

Working Principle of the MP320B Crystal Oscillator

At the core of the MP320B crystal is a quartz wafer. The properties of quartz make it an excellent material for oscillator applications. When a voltage is applied to the quartz wafer, it vibrates at the resonant frequency of the crystal. The mechanical energy of these vibrations is then converted into electrical fluctuations. These electrical fluctuations can then be amplified and applied to the load.The frequency of the electric signal produced by the quartz wafer is precise and constant. The MP320B crystal utilizes the frequency of vibration when struck by electrons. When a voltage is applied, the quartz wafer begins to vibrate and produces a precise, constant frequency electric signal. This precise frequency is then utilized by the rest of the circuit, allowing precise timing and synchronization. The frequency of the electric signal produced by the MP320B can range from 10KHz to 50MHz depending on the specific model, [4].However, the frequency of the electric signal produced by the crystal is not always constant and can be affected by external factors such as temperature, shock, and vibration. To guard against these variables, the MP320B utilizes temperature Compensation, a feature that helps to maintain the accuracy of the oscillation frequency over a wide range of operating temperatures.

Conclusion

In conclusion, the MP320B Crystal is a versatile oscillator with a wide frequency range. Its precise and constant frequency makes it ideal for use in various wireless applications, electronic instrumentation, and radio-transceiver systems. Furthermore, its temperature compensation feature helps to maintain accuracy over a wide range of operating temperatures.
