SIT9002AC-38H18SB programmable oscillators have an oscillator as the core component with a built-in controller, a frequency generator and integrated control logic. This combination enables the oscillator to measure and adjust the frequency of the signal it produces. The programmable oscillator generates the clock signal based on the user defined frequency and accuracy settings. This allows the user to obtain the desired output frequency with minimal power consumption without the need for an external frequency reference. The internal controller can also dynamically adjust the clock frequency according to the usage scenario, which makes the device more versatile in different applications.

Another advantage of the SIT9002AC-38H18SB programmable oscillator is its low noise and low jitter characteristics. The frequency jitter typically less than 300ps, which makes it attractive in some ultra-precise applications. It also has a high operating temperature range, a wide voltage range and low EMI interference. This makes the device suitable for use in both general purpose and precision applications.

In terms of working principles, the SIT9002AC-38H18SB programmable oscillator is based on a standard Pierce oscillator configuration with a frequency synthesizer. The frequency of the oscillator is generated by an external crystal or clock generator. The oscillator frequency generator feeds a frequency synthesizer, which uses phase lock loop (PLL) and divide by N techniques to generate the user-defined frequency. At the same time, the programmable oscillator also uses EPROM or EEPROM to store related frequency information, and uses high-precision timebase reference to minimize the output frequency error.

In conclusion, SIT9002AC-38H18SB programmable oscillators are highly reliable and power efficient devices that offer control over the output frequency of a clock signal.
