Oscillators: 353SB3C14CR Application Field and Working Principle

Oscillators are electronic circuits which generate a continuous train of alternating current waveforms, via the use of active components and feedback networks, at frequencies determined by components’ values. An example of an oscillator circuit is the popular 353SB3C14CR, a voltage-controlled oscillator (VCO) designed to provide a stable output signal over a wide range of temperatures and environmental conditions.

The application of 353SB3C14CR is a wide range of commercial and military systems, as it offers exceptional performance in terms of temperature stability, frequency stability and linearity. This oscillator is suitable for a variety of applications such as telecommunication systems, test and measurement, automatic process control and other electronic systems requiring stable RF signals.

Working Principle

The oscillator consists of three main parts: the oscillator itself, a voltage-controlled element and an external tank circuit. The oscillator is a voltage-controlled amplifying device, which receives control voltages from an outside source and use them to charge and discharge a capacitor. When the capacitor reaches its maximum charge, the current reverses and the capacitor starts discharging. This is repeated continuously, producing the desired oscillations.

The voltage-controlled element of the circuit is used to alter the output frequency of the oscillations. It changes the control voltage, which, in turn, changes the current passing through the capacitor and hence, the frequency. The external tank circuit is used to determine the oscillation frequency and its stability. Usually, it consists of inductors and capacitors connected in such way that the total energy of the signal generated is equal to that of the input signal.

The 353SB3C14CR oscillator is designed to provide stable output signals with a wide range of frequencies and temperatures. With its low phase-noise and stability, this oscillator is particularly suitable for a variety of applications, such as radio navigation systems, signal generation, satellite positioning, and other systems requiring high-accuracy and stable frequency signals.

Conclusion

The 353SB3C14CR oscillator is an electronic circuit which generates an alternating output signal, at a frequency determined by an external tank circuit. The oscillator is designed for applications requiring a wide range of frequencies and a stable output.
