Working Principle of SIT9120AC-2C3-33S100.000000Y

The SIT9120AC-2C3-33S100.000000Y oscillator operates using a temperature-compensated voltage-controlled oscillator (TCXO). The frequency of the oscillator is determined by the voltage applied to the Control pin (VCTL), which can be adjusted using an external resistor. An on-chip voltage regulator ensures the voltage applied to the Control pin is kept within a safe operating range. In addition, the oscillator has an enable pin (EN), which controls whether the oscillator is active or idle. The oscillator will remain in the idle state until the enable pin is pulled low. This ensures minimal power consumption when the oscillator is not in use.

The SIT9120AC-2C3-33S100.000000Y oscillator also features a temperature-compensated crystal oscillator (TCXO), which provides long-term accuracy and stability in extreme temperature environments. The oscillator has a wide temperature range of -20°C to 85°C, and provides up to ±5ppm full temperature range frequency stability. This ensures that the frequency is kept within a certain range over the entire operating temperature range.

Conclusion

The SIT9120AC-2C3-33S100.000000Y oscillator is a high-performance clock oscillator device designed for next-generation wireless and wired networking applications. It features a temperature-compensated voltage-controlled oscillator (TCXO) to provide long-term stability and accuracy.
