Introduction

Voltage Controlled Oscillators (VCOs) are electronic components that emit a continuous and periodic signal. Frequency and shift of the output signal are determined by the input voltage. VCO-520 is a type of VCO with wide numeric and wide temperature range. This article will discuss the application fields and working principle of VCO-520.

Application Fields

VCO-520 is mainly applied in various communication systems, such as satellite communication and mobile communication. Moreover, it is also widely used in safety monitoring systems, such as infrared burglar alarm systems, voice activated fire alarms and armed security. In addition, VCO-520 is often used in playing musical instruments, digital synthesizers and other musical devices.

Working Principle

VCO-520 is a voltage controlled oscillator whose output is dependent on the input voltage. It consists of a voltage controlled oscillator (VCO), an amplifier, and an optional low pass filter. The VCO receives the input voltage and produces a signal of a frequency proportional to the input. This signal is then fed to the amplifier that boosts its power. Finally, an optional low-pass filter can be connected to reduce the harmonic frequencies of the output signal.To control the frequency of the output signal, the magnitude of the input voltage can be adjusted accordingly. When the input voltage is increased, the frequency of the output signal increases. Similarly, when the input voltage is decreased, the frequency of the output signal decreases. VCO-520 also comes with temperature compensation, which ensures the stability of the output frequency and the precision of the output signal within the operation temperature range.

Conclusion

VCO-520 is a type of voltage controlled oscillator that is widely used in communication systems, safety monitoring systems and musical instruments. It produces a signal whose frequency is proportional to the input voltage. To further stabilize the output frequency, temperature compensation is available in VCO-520.
