Working Principle

The SIT1602BC-21-18N-40.000000D Oscillator utilizes a quartz crystal resonator to generate an oscillating signal that is amplified and sent out as the output. The quartz crystal resonator is composed of a round disc of quartz, which is cut along its axis in such a way that it will have a natural resonating frequency. Through the Piezoelectric effect, when a voltage is applied, it will cause the quartz to change its shape, and thus its natural frequency changes as a function of the applied voltage. This is known as “tuning” of the crystal, and the SIT1602BC-21-18N-40.000000D is designed to precisely “tune” this crystal to provide stable frequency. The crystal also acts as a filter to remove unwanted noise, allowing precise frequency control. This allows the crystal oscillator to generate very stable frequencies over long periods of time, with very low jitter, which is essential for precise frequency control.

Conclusion

The SIT1602BC-21-18N-40.000000D Oscillator is a precision frequency control crystal oscillator designed for use in a wide range of applications. It features an integrated amplifier, low power consumption, wide temperature range, and sub-millimeter accuracy at up to 40 MHz. Its high-frequency stability and precise frequency control make it an ideal solution for digital communication, radio frequency, RFID, radar, and other high-speed applications.
