Working Principle

The SIT1602BI-81-18S-75.000000T uses a quartz-based crystal oscillator circuit comprised of quartz crystals and passive components to generate accurate and reliable frequencies. Quartz crystals have piezo-electric properties, and when an electric signal is applied to the quartz, the different vibration modes of the crystal begin to vibrate at a frequency determined by its shape, size, and composition. This frequency usually remains quite reliable over temperature, voltage, and time. The quartz crystal oscillator circuit contains additional passive components such as capacitors, inductors, and resistors to act as load elements for the oscillation of the vibration modes, forming an oscillation loop. The oscillator is connected to a separate electronic circuit for amplification, which consists of a transistor, operational amplifier, and other active components. In the amplification circuit, the oscillation signal is boosted and regulated so that it can be used accurately and output with minimal distortion.

Conclusion

The SIT1602BI-81-18S-75.000000T frequency-stabilized oscillator provides excellent performance when used in many applications. Its small size and low power consumption make it easy to use and suitable for various applications. Its excellent jitter and accuracy make it suitable for areas such as medical, military, aerospace, communication, navigation, robotic, and industrial automation process control.
