Oscillators

Oscillators can be found in a wide range of applications and are used to generate a wide variety of signals. The SIT9120AI-1B1-XXS133.333333E oscillator is a type of frequency synthesizer which is used to generate a signal that is digitally generated and locked with very low drift. It is designed for use in frequency hopping systems, code division multiple access (CDMA) systems, and other related applications.

Application Fields

The SIT9120AI-1B1-XXS133.333333E oscillator is ideally suited for use in frequency hopping systems, due to its low frequency drift and wide range of operation. The oscillator is also suitable for use in code division multiple access (CDMA) systems, because it is capable of quickly and accurately synchronizing to a given code, allowing for efficient and secure communication. Additionally, the oscillator is useful for generating and modulating signals for radio remote control systems, such as for use in remote controlled aircraft and marine vessels.

Working Principle

The SIT9120AI-1B1-XXS133.333333E oscillator is based on frequency synthesizer architecture, which utilizes a phase-locked loop (PLL) to generate a stable and precise output frequency. The frequency synthesizer consists of two components; an oscillator and a frequency divider which can be used to adjust the output frequency. The oscillator acts as the source of reference, and is typically a voltage controlled crystal oscillator (VCXO) or a voltage controlled temperature compensated crystal oscillator (VCTCXO). This reference signal is divided by the frequency divider, and is then fed back into the PLL. The frequency divider can be adjusted to achieve any desired output frequency, which can be as low as several hundred hertz, and as high as several hundred megahertz.

The output of the frequency synthesizer is then divided by an integer divider to reduce the frequency again, typically down to a range of a few kHz. This integer divider is important in frequency hopping systems, as it can be used to quickly adjust the output frequency within the range of a given frequency hop. In order to achieve a low-drift signal, the SIT9120AI-1B1-XXS133.333333E oscillator has a fractional-N divider which is capable of fine-tuning the final output frequency.

The SIT9120AI-1B1-XXS133.333333E oscillator is designed to operate within a wide temperature range, and features low phase noise and excellent jitter performance. It also has a very small footprint, and low power consumption, ensuring that it can be used in many applications where size and power usage are key considerations.

Conclusion

The SIT9120AI-1B1-XXS133.333333E oscillator is a type of frequency synthesizer, which is capable of providing an extremely stable and accurate output for use in frequency hopping, code division multiple access (CDMA), and other related applications.
