Crystals play an integral role in electronics, used in satellite receivers and networks, local radio stations, computers, and smartphones. FC4SDCBMM6.0-T1 application fields are widely used in crystal oscillators, chip operation bases, switching power supplies and other fields. The working principle is as follows.

Crystal Oscillators

Crystal oscillators use the mechanical resonance of a quartz crystal to create a stable frequency reference source. By supplying a DC voltage to two electrodes on the quartz crystal, an electric field is created, an oscillator current is generated, and a small AC signal is result provided across the crystal, resulting in a physical deformation in the crystal structure. This deformation produces a mechanical compression and stretching cycle, which feedbacks its own signal, creating an oscillation at a very precise frequency.

Chip Operation Bases

In a chip operation base, the FC4SDCBMM6.0-T1 crystal can be used to accurately adjust the output frequency of a quartz crystal vibrator. A feedback control circuit is adopted to quickly adjust the operating conditions of the quartz crystal, compensating the load capacitance of the crystal to stabilize the output frequency. By controlling the output frequency, the chip has a better control signal stabilization effect. It can also theoretically control the signal frequency within a certain range according to the user’s actual needs.

Switching Power Supplies

FC4SDCBMM6.0-T1 is often used in switching power supplies with built-in resonance circuits to adjust the output frequency twice, once for start-up, and once for steady-state. When the power supply first starts up, the frequency is set to a higher value, reducing the stress on the components of the power supply. When the circuit is stable, it will automatically reduce the load on the circuit. The measurement of the output frequency and the control of the operation frequency are realized by using the crystal oscillator to adjust the frequency.

Conclusion

FC4SDCBMM6.0-T1 crystals can be used in a variety of applications, ranging from crystal oscillators to chip operation bases and switching power supplies. The working principle is that in crystal oscillators, the mechanical resonance of quartz crystals produces a small AC signal, while in chip operation bases and switching power supplies, feedback control circuits and resonance circuits are used to adjust and measure the output frequency to control the signal\'s frequency.
