The CMX309FLC/O-UT (hereinafter referred to as CMX309) is a common type of oscillator used in various applications. This article will discuss the application fields and working principle of CMX309.

Application Fields of CMX309

The CMX309 is a miniature, low cost, temperature stable crystal oscillator. It is suitable for numerous embedded system applications, including automotive electronics, audio systems, computer peripherals, portable electronics, industrial automation, instrumentation, test & measurement, and wireless systems. The CMX309 offers reliable stability against temperature and voltage variations. It can also work in a low power consumption environment.

Working Principle of CMX309

The CMX309 utilizes a quartz crystal as an electrical resonator. Quartz is a piezoelectric material, which means it has the property of generating a voltage when subject to mechanical stress. This is the key to operating an oscillator. The quartz crystal is mechanically mounted on the surface of the semiconductor chip by a dedicated anchor. It then works together with the feedback circuitry of the oscillating circuit to form an oscillating circuit.

The quartz crystal has a certain resonant frequency. When an alternating current of this particular frequency passes through it, the crystal vibrates. The vibrations of the crystal produces an alternating voltage across its two electrodes. This voltage creates a feedback circuit with the oscillating circuit, thus forming an oscillator circuit with the quartz crystal as the resonant element. This oscillator circuit produces an output signal of reliable frequency and waveform.

The frequency of the output signal of CMX309 is mainly determined by the dimensions of quartz crystal. The frequency of the crystal can be tuned by changing the thickness of the cut of the quartz. The CMX309 offers tight frequency stability over temperature, voltage and time, making it ideal for a variety of embedded system applications.

Conclusion

The CMX309 is a miniature, low-cost, temperature stable crystal oscillator with reliable stability against temperature and voltage variations. It utilizes a quartz crystal as the basis of its operation and offers tight frequency stability over temperature, voltage and time, making it suitable for a variety of embedded system applications.
