Programmable Oscillators are widely used in applications such as phase control, frequency modulation and pulse-width modulation. SIT8009BCB21-33N is one of the most widely used Programmable Oscillators in the industry, providing users with the flexibility to customize their oscillation frequency. This article will discuss the applications fields and working principles of SIT8009BCB21-33N.
Applications of SIT8009BCB21-33N
As mentioned before, Programmable Oscillators are widely used in frequency modulation and phase control, and SIT8009BCB21-33N is particularly well suited for these tasks. Its most common application is in audio frequency modulation, where the oscillation frequency can be configured to produce sound of different volume and frequency. Additionally, it can be used in phase control circuit, such as a converter that can be used to control the speed of the motor. Other applications of this oscillator include the modulation of signal transmitters in the radio communications, and digital-to-analog converter in telecommunication systems.Working Principle of SIT8009BCB21-33N
In a nutshell, SIT8009BCB21-33N is composed of an active element (operational amplifier) that generates an oscillation frequency. The frequency of its oscillation is determined by an external resistor and capacitor connected to the pins of the oscillator. The frequency is then adjusted by changing the resistance or capacitance value. The specific way of how this oscillator works is explained by an example. When the resistor R is connected to the first pin and the capacitance C is connected to the second pin of the oscillator, the initial voltage of capacitor will be equal to the voltage of resistor. When the switch is closed, the current will flow through the resistor, charging the capacitor and raising its voltage. After reaching the threshold voltage of the operational amplifier, it will be switched on. This switch on will reset the capacitor to its initial value and the operational amplifier will become off. Then the cycle will start all over again, continuously increasing and decreasing the voltage of capacitor, resulting in oscillation with the frequency determined by the time constant of resistor and capacitor.Conclusion
SIT8009BCB21-33N is a very versatile Programmable Oscillators which can be used in various applications, such as frequency modulation and phase control. Its working principle is also quite simple: An oscillation frequency is generated by an active element which is then configured through the combination of resistor and capacitor values. As such, this oscillator is a valuable addition to any electronic system.The specific data is subject to PDF, and the above content is for reference
