IntroductionProgrammable oscillators are an important component when it comes to timing or frequency control in electronics. They have a wide range of applications, from short pulse modes to wide frequency coverage and stability. One of the most popular and ergonomic programmable oscillators is the SIT9002AC-48N33DT. It is a low cost, surface mount component that offers remarkable stability, compatibility, and low current operation. This article will discuss the applications and working principles of the SIT9002AC-48N33DT programmable oscillator. ApplicationsThe SIT9002AC-48N33DT programmable oscillator is commonly used for timing and frequency control, for applications such as:•Arbitrary waveform generation •Periodic signal synthesis •Signal regeneration •Impedance matching It can also be used to generate electrical and communications signals, measure frequency, buffer output signals, generate reference frequencies, and as a frequency synthesizer.The SIT9002AC-48N33DT oscillator offers excellent stability and accuracy, and can achieve ±8ppm and ±12ppm stability under supply voltage variations of 3.3V and 5V, respectively. With its wide range of applications, this oscillator is an ideal choice for telecommunication, radios, medical, instrumentation, industrial, and automotive electronics. Working principleThe SIT9002AC-48N33DT programmable oscillator is an electro-mechanical oscillator with a mechanical tuning fork system. It works by dividing the input into two separate paths with a mechanical component. The output is then generated by the interaction between the two paths.The oscillator is powered by a voltage source, typically 3.3V or 5V, and the input frequency is determined by the setting of the integrated quartz oscillator or tuning fork component. The frequency is then multiplied by the mechanical component to generate the output signal.The output signal can be adjusted using an external control pin, which can be set to either low or high. When the pin is set to low, the oscillator is set to the nominal frequency, and the output signal is at the maximum frequency. On the other hand, when the pin is set to high, the oscillator is set to the maximum frequency, and the output signal is at its lowest frequency. The switching frequency is controlled by an integrated temperature compensation component crystal. This component is designed to accurately compensate for temperature drift and variations, to ensure stable and accurate frequency output. ConclusionThe SIT9002AC-48N33DT programmable oscillator is a great choice for frequency control applications. It offers a wide range of features, such as excellent stability and accuracy, low current operation, wide frequency coverage, and a low cost surface mount component. In addition to its wide range of applications, the SIT9002AC-48N33DT works by dividing the input into two separate paths with a mechanical component and an integrated quartz oscillator or tuning fork component. The output signal is then generated by the interaction between the two paths.Finally, the frequency output is further stabilized by an integrated temperature compensation component crystal. This provides maximum accuracy and stability under varying temperatures.
