Crystals: FC-13A 32.7680KA-AG Application Field and Working Principle

Crystals have been used for a variety of electronic applications for over a century. Among them, the FC-13A 32.7680KA-AG is a very common type of crystal oscillator widely used for frequency control and timing applications. This article examines the application field and working principle of FC-13A 32.7680KA-AG crystals. FC-13A 32.7680KA-AG crystals operate in a wide range of fields. They are widely used in communication and consumer products such as radio receivers, wireless devices, telephones, digital cameras, televisions, PCs, and other digital audio-visual devices. In addition, they find application in military equipment. FC-13A 32.7680KA-AG crystals work on the principle of mechanical resonance. In a quartz crystal, electrons in the crystal are subjected to a force that is resonant with the frequency of the crystal. As a result, mechanical vibrations are generated and the frequency is determined by the mass, size and shape of the crystal. The frequency of a quartz crystal is also affected by its temperature. The temperature coefficient of frequency is defined as the change in frequency with respect to a change in temperature. A crystalline material will usually have a negative temperature coefficient, which means that its frequency increases with an increase in temperature. FC-13A 32.7680KA-AG crystals are fabricated with a variety of package sizes and frequencies. The standard frequency range of the crystal is 20 KHz to 50 MHz and the frequency tolerance is typically up to ±20 ppm at 25°C. The frequency stability and accuracy varies depending on parameters such as the frequency range, temperature coefficient, and dimensional tolerances. The oscillation circuit of FC-13A 32.7680KA-AG crystals can be divided into two types. The most common type is the Pierce Oscillator and the alternative type is the Colpitts Oscillator. In the Pierce Oscillator, the crystal is connected between the transistor’s base and emitter and operates in a positive feedback mode. In the Colpitts Oscillator, the crystal is connected between the inverting and non-inverting input of the transistor and operates in an inverted feedback mode. FC-13A 32.7680KA-AG crystals are typically packaged in a hermetically sealed package, which is designed to provide long-term stability and reliability. Other features available on the crystal range from temperature compensated frequency adjustment to frequency modulation. In conclusion, FC-13A 32.7680KA-AG crystals are a type of quartz oscillator widely used in many applications. They operate on the principle of mechanical resonance and offer a wide range of frequencies and frequency tolerances. They are usually packaged in hermetically sealed packages and feature temperature compensated frequency adjustment and frequency modulation.
