Oscillators

Oscillators are electronic devices that generate periodic, oscillatory electrical signals. Oscillators can be categorized into few types such as harmonic oscillators, relaxation oscillators, crystal oscillators and so on. SIT1602BI-23-33E-32.768000D is an example of crystal oscillators, which are popular frequency control elements.

Application Field

SIT1602BI-23-33E-32.768000D is commonly used for clock synchronization, due to its capability of providing a high frequency accuracy. With a frequency accuracy of up to +/- 10 ppm, it can provide a highly stable clock signal. Moreover, its very low power consumption makes it ideal for applications with limited power budget. SIT1602BI-23-33E-32.768000D is also found in various communication systems. It is used to generate a reference signal for transceivers and modems, enabling them to perform accurate frequency hopping and burst synchronization. It is also used in global positioning systems to generate the 1 MHz reference signal for the receivers. Besides, SIT1602BI-23-33E-32.768000D can also be used in medical devices, such as ultrasound machines and vital-sign monitors, for ensuring accurate operation of the devices.

Working Principle

SIT1602BI-23-33E-32.768000D basically contains two components – an oscillator core and a frequency tuning circuit. The oscillator core generates clock signals while the frequency tuning circuit helps to adjust the frequency of the signals. The core part consists of a quartz crystal resonator which is connected to an amplifier circuit that amplifies the signal generated by the resonator and creates a feedback loop. The frequency tuning circuit in SIT1602BI-23-33E-32.768000D is based on the Pierce oscillator principle. This principle relies on negative resistance, which is generated by the interaction of two transistor circuits. The negative resistance helps to reduce the noise generated in the oscillator circuit, further improving its frequency accuracy. The frequency tuning circuit is also equipped with an electronic tuning diode. This diode helps to precisely adjust the frequency of the signals by changing the resonating frequency of the crystal resonator. Additionally, the tuning circuit has a voltage-controlled tuning element which allows the user to adjust the frequency of the oscillator with an external voltage source.

Conclusion

In summary, SIT1602BI-23-33E-32.768000D is a highly accurate crystal oscillator which is suitable for applications such as clock synchronization and communication systems. It works on the principle of a quartz crystal resonator with a Pierce oscillator frequency tuning circuit. Its high frequency accuracy, low power consumption and flexible tuning make it an ideal choice for various applications.
