Oscillators: SIT1602BC-72-25E-38.000000E Application Field and Working Principle

Oscillators are external circuits that generate electrical signals based on a predetermined frequency. They are primarily used in regulated power supply systems, generating pulses for synchronization and signal control. The SIT1602BC-72-25E-38.000000E oscillator, manufactured by Stackpole Electronics, is a programmable oscillator designed for applications requiring high performance. This article discusses the application field and working principle of the SIT1602BC-72-25E-38.000000E.

Application Field

The SIT1602BC-72-25E-38.000000E oscillator has a wide range of applications, from automotive to telecommunications. Its high performance, efficiency, accuracy, and reliability make it suitable for critical applications such as video and optical networks, automotive robots, factory automation, and medical equipment. It can also be used for applications involving frequency dividers, low voltage and current sensors, clock generation, and other control functions.

Working Principle

The SIT1602BC-72-25E-38.000000E oscillator uses a voltage-controlled oscillator (VCO) to create a signal waveform. This wave form is then applied to a frequency comparator that monitors the frequency of the waveform. If the output frequency deviates from the reference frequency, the frequency comparator generates negative feedback to adjust the amplitude of the waveform. This negative feedback is then used to adjust the voltage level of the VCO and keep the output frequency constant.

The SIT1602BC-72-25E-38.000000E oscillator also uses a programmable feedback loop to further fine-tune the output frequency. This loop is composed of a programmable counter and logic circuit. The counter counts the number of pulses generated by the VCO and the logic circuit compares them with the reference frequency. If the number is too low, the logic circuit adjusts the voltage level of the VCO to increase the number of pulses generated and vice versa. This mechanism constantly adjusts the output frequency, ensuring it is always within the correct range.

The SIT1602BC-72-25E-38.000000E oscillator also includes a programmable pre-divider, which can be used to divide the output frequency for applications requiring lower frequencies. The preference divider is used to adjust the accuracy of the frequency and enable the oscillator to work with different types of input signals.

Conclusion

The SIT1602BC-72-25E-38.000000E oscillator is a highly reliable and accurate oscillator with a wide range of applications, from automotive to telecommunications. It works by using a voltage-controlled oscillator and a frequency comparator to generate an output signal of a predetermined frequency. The oscillator also includes a programmable feedback loop and pre-divider to fine-tune the output frequency and maintain a certain level of accuracy. All of these features make the SIT1602BC-72-25E-38.000000E oscillator a great choice for critical applications.
