The SIT8208AC-21-18S-4.000000Y oscillator belongs to a kind of oven controlled oscillator (OCXO) and has good frequency stability, low noise and low temperature drift. Its applications in electronic equipment are various.

Applications

The SIT8208AC-21-18S-4.000000Y oscillator is suitable for analog signal applications such as scientific instruments, test and measurement equipment, aerospace communications, and positioning servos. In these applications, it can be used to provide a stable reference frequency signal to drive or control the circuit. In addition, it can also be used for electronic equipment and instrumentation systems where frequency accuracy or stability is required.

Working Principle

The working principle of the SIT8208AC-21-18S-4.000000Y oscillator is based on a quartz crystal resonator. It is made up of a quartz plate and a pair of electrodes. When subjected to the appropriate electrical pulse, the quartz plate will vibrate as it is piezoelectric. The frequency of the electrical signals generated by this vibration is extremely stable and precise. These signals are then amplified, filtered and regulated by an amplifier and the output is a stable and precise frequency signal.

The SIT8208AC-21-18S-4.000000Y oscillator also has the advantage of low power consumption. The temperature of the oscillator is controlled by an oven, which keeps the temperature of the oscillator constant and maintains the frequency stability of the output signal. This oscillator uses a dual-clock structure, which can reduce the temperature drift and provide good frequency stability.

In addition, this oscillator has a wide working temperature range. It is temperature compensated in the range of - 55°C to + 85°C, and can maintain excellent frequency stability within this temperature range. It also has good long-term performance and its frequency drift is much lower than commonly used oven oscillators. The life of this oscillator is up to 20 years under normal environmental conditions.

Conclusion

In conclusion, the SIT8208AC-21-18S-4.000000Y oscillator is an excellent choice for application in analog, accuracy-oriented situations such as scientific instruments, test and measurement equipment, aerospace communications, and positioning servos. It has a wide working temperature range, low power consumption, low temperature drift, good frequency stability and a long service life, which makes it one of the best choices in frequency control.
