Crystals are vital components in a wide array of electronic devices. From computers to smartphones, crystals are responsible for providing the clock signal, setting up the frequency and timing of a device operations. In particular, the 402F307XXCDT crystal oscillator is a popular choice for its robust performance and small size. It has a wide variety of potential application fields.

The 402F307XXCDT is an SMD-mountable oscillator with a frequency operating range from 30Khz to 75 MHz. It has a standard operating temperature range from -20°C to 70°; however, depending on its specific model, it can also handle extreme temperatures with an operating range from -40°C to 85°C. With a supply voltage range from 1.9V to 4.5V, the device is made for general purpose and consumer electronics applications.

In terms of its applications, the 402F307XXCDT crystal oscillator can be used in communications, such as cellular phones, base stations, and network application. It can also be used in consumer electronics, including GPS systems, media players, and digital cameras. Moreover, the device is suitable for industrial application that require tight control on the frequency, such as motor or power electronics systems.

The primary working principle of the 402F307XXCDT crystal oscillator is based on the piezoelectric effect. This effect entails the conversion of mechanical energy into electrical energy, and vice versa. Like other types of crystals, the 402F307XXCDT consists of a quartz crystal that has been cut precisely in the form of a rectangular plate, so that it would resonate at oscillations with a specific frequency. This resonance is characterized by a piezoelectric response, where the voltage applied to the crystal oscillates so it can oscillate itself at a particular frequency.

The flow of a current also produces a physical mechanical stress on the quartz crystal. This physical stress produces a vibrational pattern at a specific frequency and amplitudes depending on the applied current, which in turn sustains the oscillation frequency of the crystal. Because of this physical-electrical energy conversion, the device produces an output signal that oscillates at precisely defined frequencies, which is exactly the reason why many electronic systems benefits from the presence of quartz crystals.

In conclusion, the 402F307XXCDT crystal oscillator, with its robust performance, small size, and wide range of potential application fields, is a reliable component in an ever-growing range of electronics devices. Its functioning is based on the macroscopic and microscopic aspects of piezoelectricity, where the physical components of the crystal absorb and release energy in reaction to electrical current.
