The advantages of SIT9120AC-2C2-25E100.000000T compared to other oscillators is that it has a high frequency stability and excellent noise figures. Its combined features make it the best choice in precision timing and frequency stabilizing applications where long-term accuracy is of the utmost importance.

Working Principle

SIT9120AC-2C2-25E100.000000T is based on an oscillator chip that is an integrated circuit comprising of the oscillator, an amplifier, and the frequency divider circuits. This design makes the oscillator highly efficient and reliable since the individual components are all interconnected and operate as a single device.

The oscillator has a quartz resonator, usually the quartz crystal is cut in the shape of a ladder where the two vertical sides correspond to the plates of a capacitor. This generates the electric charge that constitutes the oscillation frequency. The frequency of oscillation is determined by the shape and size of the cut and the quantity of quartz used.

The frequency of the oscillator is controlled by using a control voltage generated by a Frequency Control Voltage Generator (FCVG). This FCVG is an on-chip device that provides the control voltage to modify the resonator frequency. The oscillator’s stability and accuracy are also enabled by using a temperature compensation scheme, to further reduce temperature-dependent variations.

The frequency signal is then divided down by the frequency divider circuits to generate an accurate output signal. The output signal is then amplified to match power supply and external device requirements. The frequency divider circuits also allow for the customization of the output frequency by providing different division ratios.

Conclusion

SIT9120AC-2C2-25E100.000000T is a precision oscillator developed by Sitronix Technology Corporation for accurate timekeeping and timing control applications. Its high frequency stability, excellent noise figures, temperature compensation scheme and frequency divider circuits make it the ideal choice in precision timing systems where long term accuracy is of the utmost importance. It can be used in a variety of frequency-dependent applications including set-top boxes, clocks, toys, security systems, automotive remote keyless entry systems, and electronic garage door openers.
