It fits a wide variety of commercial and industrial applications such as frequency controllers, signal generators, power management systems, and served as the standard reference oscillator for a variety of precision time-keeping applications.

The working principle of AX7DCF3-75.0000C is based on quartz crystal and its characteristics. This oscillator consists of an amplifier, a quartz crystal resonator and an external timing capacitor. The quartz crystal resonator consists of a massive substrate, mounted with an external circuit to form an oscillator. When a voltage is applied to the quartz crystal, the crystal vibrates at its natural frequency and produces a characteristic sound. The frequency of the sound is dependent on the mechanical properties of the crystal. The electrical signal from the crystal is then amplified by an amplifier, producing an oscillating signal.

The frequency is set by the external capacitor, which is set to tune the crystal to the desired frequency. A feedback loop is then built to stabilise the frequency and ensure the oscillation stays within the required limits. The voltage applied to the crystal determines the frequency of the output, and so the capacitor and external control circuitry can be used to adjust the output frequency.

The overall performance of the AX7DCF3-75.0000C is excellent, with a rated frequency tolerance of 0.5 ppm or 0.0005%. It has a wide frequency range of 1 KHz to 250 KHz and a wide operating temperature range of -40°C to + 85°C. It demands low power consumption up to 6 mA and provides higher power handling, greater immunity and better robustness. Due to its excellent features and reliable performance, AX7DCF3-75.0000C can easily be used in various industrial and consumer electronic applications.
