Crystals

Crystals are widely used electronic components in various electronic devices. Their primary function is to convert electrical signals into either mechanical vibrations or electromagnetic oscillations. ABL-3.579545MHZ-B2 is an example of a crystal that has a wide range of applications and a variety of working principles. This article will explore what they are used for and how they operate.

Application Field

ABL-3.579545MHZ-B2 crystals are widely used in a variety of electronic systems such as radios, televisions, computers, mobile phones, industrial systems and many more. As radio frequency (RF) crystals, they are typically used for sustaining accurate frequency for radio and microwave signals in communication systems, broadcast receivers and fixed frequency oscillators. Due to their high precision, stability and reliability, ABL-3.579545MHZ-B2 crystals are highly demanded in various applications. Furthermore, they can bear an operating temperature of between -30 to +85 degrees Celsius.

Working Principle

ABL-3.579545MHZ-B2 crystals operate on the principle of quartz crystal resonators. These devices consist of a quartz crystal that has been cut into a particular knick shape, containing two metal electrodes, allowing two signals to travel through it. When an electrical voltage is applied to the electrodes, the quartz crystal begins to vibrate, creating an electric current on each side of the device. This generates a frequency that is equal to twice the frequency of the electrical signal, but with the same phase. This frequency is the fundamental frequency of operation for the crystal, and is typically in the radio frequency range. This frequency is used for digital signal processing.

In order to produce an output frequency different from the fundamental, a quartz crystal can be designed to have multiple electrode layers, allowing for other frequencies to be generated. This process is referred to as overtone or harmonic mode operation. In this mode, the frequency of the output is usually an integer multiple to the fundamental frequency. For instance, overtone mode operation of ABL-3.579545MHZ-B2 can produce 7.159090MHz and 10.738684MHz.

In addition to overtone operation, ABL-3.579545MHZ-B2 crystals can also be operated in a parallel resonant mode. In this mode, the crystal is connected in an LC circuit such that the output is rotationally symmetric. The output frequency is dependent on the capacitance of the circuit, as well as the inductance of the device. This mode is typically used for communication systems, as the output frequency does not vary with the applied voltage and, thus, remains stable.

Conclusion

ABL-3.579545MHZ-B2 is a quartz-based crystal that can be used in various electronic systems such as radios, televisions, computers and mobile phones. It operates on the principle of quartz crystal resonators, using a quartz crystal that has been cut in a particular shape containing two metal electrodes. With this type of crystal, it is possible to design different electrodes, allowing for other frequencies to be generated, including overtone and parallel resonant mode operations. Due to its high precision, stability and reliability, ABL-3.579545MHZ-B2 is highly demanded in many different applications.
