Voltage Controlled Oscillators (VCOs) are commonly used in electronic system design and come in a variety of shapes and sizes. The VCO-104 is one such device, and this article provides an overview of its application field and working principle.

Overview of VCO-104

The VCO-104 is a miniaturized and cost-effective IC with a 0.5" footprint and a compact design that makes it ideal for portable and space-constrained applications. It contains a voltage-controlled oscillator that generates a square-wave output up to 40MHz when driven by DC or AC voltages. The oscillator has an adjustable control voltage range of +/- 3V, a wide output frequency range of 10kHz – 40MHz, and a high output impedance.

Application of VCO-104

The VCO-104 is widely used in communication systems such as cellular phones, wireless data links, and satellite receivers. It can also be used for frequency synthesis and modulation applications, including PLLs and frequency-hopping spread spectrum systems. Additionally, it can be used for clock and timing applications, where its low noise and high frequency stability make it an ideal choice.

Working Principle of VCO-104

The VCO-104 works by applying a voltage to the base voltage control pin (Vin). This voltage is compared to the reference voltage that is generated internally and when these voltages are equal, the oscillator output frequency will be at its nominal frequency. The higher the voltage applied to the Vin pin, the higher the output frequency will be. Voltage changes applied to the Vin pin will cause the output frequency to change; this is the basis of voltage controlled oscillators.

Conclusion

In conclusion, the VCO-104 is a miniature voltage-controlled oscillator device that is widely used for communication systems and other applications. It has an adjustable control voltage range of +/- 3V, a wide output frequency range of 10kHz – 40MHz, and a high output impedance. Its working principle is based on the comparison of internally generated reference voltage with an externally applied voltage, which results in an output frequency that is proportional to the applied voltage.
