Working Principle

The working principle of VG-4231CA 2.0480M-ZGRC oscillator is based on a quartz crystal resonator, which is a vibrating element of trigonal structure. Quartz crystal has piezoelectric effect which means the crystal can vibrate under an electric field similarly to a tuning fork. When the quartz crystal is connected with the oscillator, it is supplied with electrical energy from the oscillator and begins to vibrate. The oscillator circuit can be divided into two parts: an amplifier connected to the crystal, which is in series with a frequency-determining load network.

The quartz crystal’s own vibration determines the frequency of oscillations in the circuit, and its resonant frequency (oscillation frequency) is determined by the crystal’s geometry and the load capacitance. The output from the amplifier is generated by the resonance of the crystal and the load network, and the oscillator will generate a stable signal at its designated frequency.

In the actual circuit, feedback from the output signal is taken to the amplifier, which causes increase in the gain. This prevents the oscillation frequency from being affected by minor changes in the environmental temperature and any external disturbances.

VG-4231CA 2.0480M-ZGRC oscillator offers great accuracy and stability against temperature variation, and is widely used in various fields such as communications, computers, telecommunications, etc.
