Programmable Oscillators

Oscillators are electronic components that produce repetitive signals. Programmable oscillators are electronic components designed for the purpose of producing signals at predefined frequencies and phases. They provide the user with the flexibility of programming the frequency, phase, and cycle parameters of their signal. This feature makes them an ideal choice for applications that require precise timing.

Working Principle

The SIT8008BCR8-28S works by dividing the input frequency by a programmable value. This is done by means of a Phase-Locked Loop (PLL). A PLL is a type of electronic circuit that is used to generate a signal whose phase and frequency are related to the reference frequency. The SIT8008BCR8-28S uses this principle to generate signals with adjustable frequency and phase.

The SIT8008BCR8-28S consists of three main components: the reference oscillator, the PLL, and the output buffer. The reference oscillator is used to generate a reference frequency. The PLL then uses this reference frequency to generate the programmable output frequency. The output buffer is used to amplify the signal and to reduce the noise. The SIT8008BCR8-28S also includes a brake control pin, which is used to reduce the output frequency.

Conclusion

The SIT8008BCR8-28S is a programmable oscillator with adjustable range and duty cycle. It is an ideal choice for applications that require precise timing and frequency control. The SIT8008BCR8-28S works by means of a PLL, which divides the reference frequency by a programmable value to generate the output signal. It is commonly used in communications and wireless applications, embedded systems, medical systems, and automotive applications.
