Oscillators

Oscillators are electronic circuits that are designed to generate cyclic signals with defined amplitude, frequency, and phase. These signals are used in a wide variety of applications, such as timing, frequency control, and data communication. One such oscillator, the SIT1602BI-11-28N-66.666600E oscillator, is especially useful in many applications due to its wide range of frequency stability and accuracy.

Application Fields

The SIT1602BI-11-28N-66.666600E oscillator has been used primarily for low frequency clock generation and timing applications due to its wide frequency stability range and accuracy. It is particularly beneficial for use in small and portable devices, including battery operated devices, because of its low power consumption. The oscillator is also popular in automotive applications, for providing low frequency clocking signals, as well as in military, aerospace, and telecommunications applications.

Working Principle

The SIT1602BI-11-28N-66.666600E oscillator works on the principle of electronic feedback control. It uses a voltage controlled oscillator (VCO) to generate a signal with a variable frequency and amplitude, which is then fed back into the oscillator in order to maintain a steady frequency and amplitude. The VCO is controlled by two external signals, one of which determines the frequency of the VCO oscillation and the other of which determines its amplitude. The oscillator uses a phase locked loop (PLL) to adjust the amplitude and frequency of the output signal in order to keep the signal at the correct frequency. The PLL contains a phase detector that compares the frequency of the VCO to that of a reference oscillator. When a mismatch is detected, the PLL will adjust the frequency or amplitude of the VCO signal to match that of the reference oscillator. The oscillator also uses temperature compensation to ensure accuracy and stability over temperature changes.

Conclusion

The SIT1602BI-11-28N-66.666600E oscillator is a highly accurate and stable device that is used in a variety of applications, including automotive, military, aerospace, and telecommunications. Its wide frequency stability range and accuracy make it a great choice for low frequency clock generation and timing applications in small portable devices. The oscillator works on the principle of electronic feedback control and uses a VCO to generate a signal, which is then fed back into the oscillator to maintain the frequency and amplitude. Additionally, temperature compensation is used to ensure accuracy and stability over temperature changes.
