Oscillators come in various forms and their functions can vary depending on the application. One type of oscillator seen in the industrial control market is the SIT1602BC-71-XXS-66.666000D. This product is designed to provide stable and reliable oscillator frequency control for higher-precision applications.

Application Field

The SIT1602BC-71-XXS-66.666000D Oscillator is designed for use in industrial environment applications including motor control applications, motion controllers, and PLC. It is typically used in applications where frequency accuracy and precision is critical. This oscillator has a temperature stability range of up to -50°C to +100°C and a frequency stability of up to ± 10ppm. This makes the SIT1602BC-71-XXS-66.666000D a great choice for use in precision equipment.

In addition, this oscillator is capable of providing a low phase noise and wide frequency range with a minimum frequency of up to 66.666MHz. This makes it suitable for applications requiring low phase error, enhanced signal to noise ratio, and signal purity in harsh environmental conditions.

Working Principle

The SIT1602BC-71-XXS-66.666000D Oscillator operates according to the Pierce oscillator design. This design incorporates a quartz crystal as the oscillation element, which offers very good frequency stability over temperature and more precise control compared to other oscillator designs. The quartz crystal is also very resistant to temperature change, with a temperature coefficient of stabilisation of up to ± 0.1ppm/°C.

To achieve this performance, the oscillator is driven by a Schmitt trigger. The Schmitt trigger is a type of comparator that can switch between two voltage levels when given a specific input voltage. When the input voltage exceeds a certain threshold (known as the high threshold), the output of the trigger will go high. When the input voltage drops below a certain threshold (known as the low threshold), the output of the trigger will go low. This switching process is repeated continuously, generating a square wave.

The output square wave is then connected to the quartz crystal, which acts as a filter to filter out unwanted frequencies. This allows the oscillator to produce a signal with the frequency you desire. The result is a stable and precise oscillation signal which can be used for a variety of industrial applications.

Conclusion

The SIT1602BC-71-XXS-66.666000D Oscillator is a great choice for industrial control applications due to its high precision and frequency accuracy. It offers a wide frequency range and low phase error, making it suitable for use in applications requiring signal purity in harsh environmental conditions. It is driven by a Schmitt trigger, which complements the quartz crystal to provide a stable and precise oscillation signal.
