Working Principle

At the heart of the SIT1602AI-12-18S-72.000000E is a four-sector active signal divider circuit. This circuit is used to divide the reference frequency, generated by the oscillator, into four output signals. The four output signals are then used to generate the quadrature waveform.Each output signal is a perfect sine wave which is generated by the active signal divider. The sine waves are then fed into separate circuits that filter out any harmonic content and normalize the frequency of each output signal. Once the output signals are normalized, they are used to generate the quadrature waveform.The quadrature waveform is then used to generate the accurate frequency reference that is required by the electronic equipment. The frequency reference is generated by the active signal divider which is driven by the oscillator. The oscillator is responsible for maintaining the accuracy of the frequency reference over long periods of time.

Conclusion

The SIT1602AI-12-18S-72.000000E oscillator is a versatile oscillator that can be used in a variety of consumer, military, aerospace, and telecommunications applications. It features a low current design and a wide operating voltage range, making it suitable for a variety of uses. It also uses a four-sector active signal divider circuit to generate accurate frequency references for use in electronic equipment.
