Crystals

Crystals are used in a variety of applications, from radio frequency communications and sound systems to medical imaging and industrial instrumentation. Crystals play a key role in modern civilization, providing a reliable and accurate means of measuring frequency and producing a known, stable output. In this article, we will discuss in detail the application field and working principle of CSA309-12.000MABJ-UB.

Application Field

CSA309-12.000MABJ-UB is a series of quartz crystals designed for high performance applications. It is primarily used for clock and timing reference for MCU, FPGA, DSP, and other circuit board applications. The CSA309 series combines mechanical and electrical stability, remarkable temperature performance, excellent accuracy, and compact size.

It is compatible with SMA, SMD, PTH, and TIP package types and has a frequency range of 7.5 to 89 MHz. It features excellent shock resistance, high stability across a wide temperature range, and is ideal for high frequency and high accuracy applications.

Working Principle

The CSA309-12.000MABJ-UB is a quartz crystal oscillator that works by vibrating a quartz crystal at its resonance frequency when a voltage is applied. Quartz crystals are well known for their piezoelectric properties, which means they will generate an electrical charge when vibration is applied. This process is called electromechanical resonance.

The crystal has two electromagnetic plates that are placed on either side of a quartz crystal. When a voltage is applied to one of the electrodes, the quartz crystal vibrates at its natural frequency creating an alternating current between the two plates. This current is known as the oscillation and is unaffected by environmental factors such as temperature, humidity, and pressure.

A quartz crystal oscillator is a device consisting of an amplifier, a quartz crystal resonator, an oscillator circuit and an output buffer. The amplifier receives an input signal, amplifies it and sends it to the quartz crystal resonator. The resonator then converts the signal into an oscillation corresponding to its resonance frequency. The oscillator circuit then creates a stable frequency by combining the oscillations and sending them to the output buffer. The output buffer then filters the frequency and sends it to the output.

Conclusion

CSA309-12.000MABJ-UB is a quartz crystal oscillator designed for high performance applications. It has a wide frequency range, excellent shock resistance and stability over temperature, making it ideal for high frequency and accuracy applications. The crystal works by vibrating a quartz crystal at its resonance frequency when a voltage is applied, which is then amplified and converted into an oscillation frequency before passing through an oscillator circuit to create a stable output frequency.
