This makes it a good solution for applications that require high stability in extreme temperatures. Additionally, it is equipped with a built-in protection circuit that prevents it from being damaged by overvoltage and overcurrent situations.

Work Principle

The SIT1602BC-81-33E-25.000000T oscillator is a quartz crystal-controlled oscillator. The quartz crystal is the core of crystal oscillator and is a piezoelectric material, whose shape is similar to a tuning fork. Its size is small and its frequency is high. When the DC voltage is applied to its two electrodes, it will vibrate according to the voltage level and resonance frequency.

The working principle of the SIT1602BC-81-33E-25.000000T oscillator is to use the quartz crystal as a resonator to generate a frequency. The signals from the quartz crystal are amplified by the amplifier and feedback to the quartz crystal, forming a regenerative loop. This process is repeated many times, and an output signal with a constant frequency is obtained.

In addition, the SIT1602BC-81-33E-25.000000T oscillator is equipped with an accurate frequency trimming circuit to adjust the output frequency. This is done by changing the capacitance of the external crystal or the internal varicap diode to make the tuning circuit closer to the resonance frequency of the quartz crystal. The result is a more accurate and stable frequency output.

Conclusion

To sum up, the SIT1602BC-81-33E-25.000000T oscillator is a highly stable and reliable signal source for electronic projects. Its wide frequency and temperature range make it suitable for many different applications, from medical to automotive. Its crystal-controlled working principle allows for accurate frequency trimming, providing stable signals even in extreme temperatures.
