The quartz crystal has unique properties that make it an effective electronic component in oscillators, signal filters and resonators. The MC-146 32.7680KA-A3:PURE SN is one such crystal, intended for use in high-frequency signal processing applications.

MC-146 32.7680KA-A3:PURE SN Application Field

The MC-146 32.7680KA-A3:PURE SN crystal has a high frequency stability and precise tuning characteristics, making it ideal for applications such as tuning of radio and television broadcasts, cellular phones, and for use as clock oscillators in microprocessors. It is also used in precision timing circuits for precise clocking. It is highly reliable, with a ~100x higher cycle life compared to ceramic filters, and it offers superior temperature compensation characteristics compared to standard watch crystals.

MC-146 32.7680KA-A3:PURE SN Working Principle

The MC-146 32.7680KA-A3:PURE SN works by leveraging the piezoelectric effect of quartz. Piezoelectricity is an inherent property of quartz in which a mechanical vibration applied to the crystal will create a voltage (and vice versa). When an electrical voltage is applied to the crystal, it compresses and decompresses in a regular fashion which resonates at a frequency determined by the mass and size of the crystal. This resonance is known as the fundamental frequency. If a higher frequency than the fundamental is applied, the crystal will begin to oscillate at a frequency determined by its cut angles and thicknesses called overtone frequencies.

The resonance of the crystal can be manipulated by changing the thickness, size or shape of the crystal. By increasing the thickness of the crystal, the resonance frequency increases. Conversely, by decreasing the thickness, resonance frequency decreases. Other characteristics such as resonator shape, cut angle and temperature can also be used to manipulate the resonance frequency. This can be used to create more precise tuning of specific frequencies with minimal error.

Conclusion

The MC-146 32.7680KA-A3:PURE SN crystal has a range of applications in high-frequency signal processing applications due to its outstanding resonator performance and frequency stability. Its working principle is based on the piezoelectric effect of quartz which allows for precise frequency tuning by adjusting thickness, size and shape of the crystal. This makes it an ideal choice for use in radio and television broadcasts, cellular phones, and microprocessor clock oscillators applications.
