VG-4231CA 32.7680M-FGRC Application Field and Working Principle
As one kind of oscillators, VG-4231CA 32.7680M-FGRC is widely applied in providing a stable frequency in the electronic circuitry. Frequency can be modulated for a variety of purposes and when VG-4231CA 32.7680M-FGRC output is steady and accurate with voltage control, it can be used to build high frequency oscillator circuit.
VG-4231CA 32.7680M-FGRC consists of solid crystal wafer inside epoxy block, with a case to protect the component and a section for terminals. The crystal inside provides a stable frequency based on a wafer movement and a voltage regulator module. This wafer movement is achieved by the piezoelectric effect when it is put under pressure. Piezoelectricity refers to the electric potential induced when a mechanical strain is applied on a suitable material, and the reverse effect of electric field applied to induce strain on the material.
The crystal oscillators refer to the frequency circuits that rely on crystal oscillator to condition the signal. In its conducting state, the oscillation frequency can be modulated by controlling its output voltage, and the output signal is usually sine waveform, square waveform or triangle wave. The VG-4231CA 32.7680M-FGRC has a moderate power consumption, high stability, good repeatability and low cost.
The working principle of VG-4231CA 32.7680M-FGRC is to use the resonance frequency of the piezoelectric crystal to generate an output signal. Its output is an oscillation signal, which drives two LC resonance circuits in parallel, and induces the L/C tank in the oscillator into resonance. The two resonance stages work in parallel, so the phase difference between their outputs is stable, and their operating frequency is stable and accurate. The two stages are connected by an amplifier with low phase noise, and a high stability voltage controlled oscillator (VCO) is composed.
In addition, VG-4231CA 32.7680M-FGRC also works with a temperature compensating thermistor to reduce the thermally induced oscillator drift, to maintain its stability. This oscillator is widely used in wireless communication systems, such as CDMA, PCS, WI-FI and so on, as well as in industrial, military and medical systems.
