Programmable Oscillators: SIT9002AI-38H25SQ Application Field and Working Principle

A Programmable Oscillator is an electronic device that produces alternating electrical signals of adjustable frequency and amplitude. The device typically uses an motor-driven oscillator, logic device or printed circuit board, and the user can program the frequency, the amplitude, or the phase shift of the generated signals. With the advances of modern IC technology, programmable oscillator products such as Sitronix\'s SIT9002AI-38H25SQ are becoming more popular, with many applications in the industry.

This article will discuss the application field of the SIT9002AI-38H25SQ programmable oscillator, as well as a brief overview of how it works and how it can be programmed.

Application Field

The SIT9002AI-38H25SQ programmable oscillator can be applied to a wide range of applications, from telecommunications, automotive applications, and even aerospace and defense. For example, in telecommunications, the device can be used as a local oscillator for frequency modulation or as a signal generator for testing of DSP systems. In automotive applications, it can be used for frequency detection for anti-theft systems, communication links for navigation systems, and audio processing. It can also be used in aerospace applications for navigation, flight control, and radar systems.

The programmable oscillator can also be used in consumer electronics such as television, DVD players, and digital audio players. The device can act as a sound generator to produce different audio signals that can be used to drive speakers, control amplifiers and sound systems, and adjust the audio tone.

Working Principle

The programmable oscillator consists of two sections; the oscillator section and the digital section. The oscillator section consists of an oscillator with three-terminal control input, a feedback resistor and capacitor for frequency adjustment, and an output buffer. The digital section consists of a control logic circuit, a programmable logic device (PLD), memory, and a microcontroller.

The oscillator section works by generating a triangle wave with the three-terminal control input and adjusting the frequency by adjusting the feedback capacitor. The output buffer amplifies the triangle wave and sends it to the output. The digital section can be programmed to control the frequency, amplitude, and phase of the generated wave. The PLD is used to control the timing, while the memory stores the settings of the oscillator.

The microcontroller is then used to control the settings of the oscillator, allowing the user to program the settings and adjust them according to their needs. The settings can be changed by using a serial port or through a PC interface.

Conclusion

SIT9002AI-38H25SQ programmable oscillator is an excellent device for a wide range of applications. It is well suited for use in telecommunications, automotive, and aerospace applications. Its ability to be programmed and adjusted makes it a highly versatile solution for many situations. The oscillator consists of two main parts; the oscillator section and the digital section. The oscillator section produces a triangle wave, while the digital section allows for controls for frequency, amplitude and phase of the generated wave.
