SIT9120AC-2B2-25E212.500000E

The SIT9120AC-2B2-25E212.500000E oscillator is a generic product created by Silicon Labs, a specialist in the industry of timing based solutions. It represents an accurate frequency source that provides standard ‘plug and play’ frequencies on two outputs. This device is typically used in audio and video clock applications or as a sys-tem based master clock.

Application Field

The SIT9120AC-2B2-25E212.500000E oscillator provides a range of solutions for various application fields. In the audio and video clock applications, it offers precise and accurate frequencies for the generation and synchronisation of audio and video signals. Moreover, along with multi-platform programming, the device can be employed as an accurate tool for complex embedded systems, due to its high output frequencies and low jitter performance. Additionally, this oscillator is used for various timing-related applications such as server synchronisation, local oscillator, clock distribution, phase-locked loop testing and wireless communication.

Working Principle

The SIT9120AC-2B2-25E212.500000E oscillator is designed around a standard application specific integrated circuit (ASIC), containing all of the device’s components. The oscillator works by taking a clock reference frequency, typically derived from an on-board clock source, and then using it to generate two raised sine-wave outputs. The output frequencies can be changed by external crystals that the oscillator uses to control the frequency of the outputs.

The oscillator is also able to adjust its frequency based on the temperature of the surrounding environment. This is because the oscillator components are built with precision temperature compensation circuitry that compensates for any temperature discrepancies.

Furthermore, the oscillator has a very low ripple and noise behaviour, meaning that the output frequency is very quiet and does not sway or vary as much due to outside disturbances. The oscillator also has very low jitter, meaning that the output frequency is accurate and does not vary.

Conclusion

The SIT9120AC-2B2-25E212.500000E oscillator is a versatile device created by Silicon Labs. It is used primarily for audio and video clock applications, as well as for embedded system applications. The oscillator works by taking a clock reference frequency, typically derived from an on-board clock source, and then using it to generate two raised sine-wave outputs. The oscillator also has a very low ripple and noise behaviour, as well as low jitter, providing very precise and accurate outputs.
