Crystals: AB-12.000MHZ-B2 application field and working principle

Crystals means possessing nearly perfect symmetry within a given structure. AB-12.000MHZ-B2 is a kind of crystal oscillator, also know as an ECS (Electromechanical Crystal System). The ECS is a special type of oscillator circuit composed of a crystal and its appropriate drive components. AB-12.000MHZ-B2 is composed of the following components: a transistor or an integrated circuit (IC), an external DC power supply, a capacitor, an inductor, and a quartz crystal.AB-12.000MHZ-B2 is mainly used in RF (Radio Frequency) applications. It is used for receiving and transmitting radio signals, as well as other electronic applications which require a precise and accurate frequency. The AB-12.000MHZ-B2 is also used in audio equipment, video equipment, computers, communication equipment, circuit board components and other electronic products.The working principle of the AB-12.000MHZ-B2 crystal oscillator is based on the principle of Piezoelectricity. Piezoelectricity is an effect in which the crystal produces mechanical vibration when an applied electric field is placed across it. This electric field causes the crystal to deform in a curved shape. This curvature changes the electric field which causes another change in the crystals shape. The effect of this is the creation of an AC signal of the desired frequency.The electric field is produced by the AB-12.000MHZ-B2 oscillator circuit and applied to the quartz crystal by the input of the electric power supply. The amplified signal produced is then sent to the external circuit. The electric field created by the electric power supply interacts with the piezoelectric effect of the quartz crystal and causes it to vibrate at its natural resonant frequency. This vibrating signal is then converted into an AC signal of the desired frequency at the output.The AB-12.000MHZ-B2 crystal oscillator is an efficient and reliable oscillator circuit with its primary application being in RF applications. It allows for precise and accurate frequency control without the need for external components. The AB-12.000MHZ-B2 is used in audio equipment, video equipment, computers, communication equipment, circuit board components, and other electronic products. It is a reliable oscillator circuit that offers a high stability.
