Introduction to Programmable Oscillators
Programmable Oscillators are a type of electronic oscillator which can be programmed according to user-defined parameters. A programmable oscillator is capable of producing a wide variety of waveforms and frequencies, which can be used in applications such as communication systems, consumer electronics, medical equipment, industrial instruments, and more. Programmable oscillators are used to create signals of varying frequencies, amplitudes, and pulse widths in order to meet specific needs.Programmable oscillators come in many varieties, and they are usually classified according to their size and type. Small form-factor programmable oscillators are generally used in embedded applications, while larger form-factor oscillators are designed for industrial or laboratory purposes. Different types of programmable oscillators include crystal oscillators, MEMS oscillators, and surface mount technology oscillators.SIT8008AIF3-28S - Application and Working Principle
The SIT8008AIF3-28S is a programmable oscillator from Sitronix Technology Corporation that is suitable for industrial and consumer applications such as Internet-of-Things (IoT) devices, consumer electronics, and radio systems. It is capable of producing very low-frequency signals with a wide range of amplitude and width.The SIT8008AIF3-28S features a wide frequency range of 10 Hz - 10 MHz and a programmable frequency tuning range of 1 Hz - 1 MHz. It comes with an excellent power supply rejection ratio (PSRR) of -60 dB, which ensures excellent signal-to-noise performance. The SIT8008AIF3-28S is supplied in a 3-by-3 mm plastic package, which makes it ideal for space-limited applications and easy handling.The working principle of the SIT8008AIF3-28S is based on an internal voltage-controlled oscillator (VCO). The VCO operates using a parallel RC-load network, which is connected to an external load capacitor and feedback resistor. When a voltage is applied to the feedback resistor, the pitch of the output signal is increased or decreased in proportion to the voltage applied.The SIT8008AIF3-28S is also capable of supporting various waveforms, such as square wave, pulse, sawtooth, and triangular wave. It also has an adjustable duty cycle up to 50%, which enables users to easily adjust the waveform as desired.Conclusion
In conclusion, the SIT8008AIF3-28S is an excellent programmable oscillator that is suitable for a wide range of applications. Its wide frequency range, adjustable waveforms, and adjustable duty cycle make it a great choice for industrial and consumer applications. Its small package size also makes it ideal for space-limited applications.
