Crystals: 407F39D019M6800 Application Field and Working Principle

Crystal oscillators are frequency control components used in many systems such as radio, television, communications, computers and industrial systems. They basically provide a sinusoidal signal of a certain frequency, and undergo a very automated tuning process. The 407F39D019M6800 crystal is a common example of such an oscillator.

The 407F39D019M6800 crystal unit is an application specific surface mount oscillator, specifically designed for signal transmission in microwave systems. It is composed of a crystalline material cut from quartz, which moves and vibrates at a certain frequency when excited by an electrical signal. This frequency is determined by the characteristics of the crystal, such as its size, shape and cut angle.

Working Principle

The 407F39D019M6800 crystal oscillator consists of two main parts: a quartz crystal and an oscillator circuit. The quartz crystal acts as the frequency determining element and the oscillator circuit helps to generate a stable frequency. The oscillator circuit consists of an amplifier and a resonator, which help to amplify the signal from the crystal, and the amplifier acts as the feedback loop.

The frequency of the oscillator is determined by the physical properties of the quartz crystal. The crystal vibrates when a voltage is applied, and this vibration can be used to generate a sinusoidal signal whose frequency depends on the size, shape and cut angle of the crystal. As the electrical signal is amplified in the amplifier, the frequency of the oscillator is locked to the frequency of the quartz crystal. The oscillator will then produce a stable output signal.

Applications

The 407F39D019M6800 crystal oscillator provides a cost-effective solution for microwave systems. It is suitable for both automotive and commercial telecommunications applications. It is also used in military, aerospace, and wireless communications. The 407F39D019M6800 is used in systems such as Global Positioning System (GPS), ultra-wide band (UWB) radar systems and frequency hopping radios.

The 407F39D019M6800 also has a high frequency stability, making it suitable for other applications such as test equipment, medical equipment and scientific instruments. Other common uses for the crystal oscillator include virtual reality systems, oscilloscopes and tuning of television receivers.
