This type of device is useful for establishing an oscillatory circuit, as well as for determining precise signal frequencies. The 402F4001XIKR is made up of a resonator, a capacitor, and an electronic circuit, which together form a device that can produce a signal at a specific, pre-determined frequency. The operating temperature range of this oscillator is -55 to 130°C.

Application Field

Since this crystal oscillator is capable of providing accurate frequencies with minimal drifting over time and temperature, it is suitable for use in a variety of electronic systems. These include computers, data storage and communications, mobile phones, digital audio systems, and other applications where precise timing and frequency accuracy are required. It is also commonly used as an accurate reference clock in frequency counters and other kinds of test equipment.

Working Principle

The 402F4001XIKR uses the piezoelectric effect to generate a precise frequency. This effect takes place when a crystal is subjected to an alternating electrical field. The crystal then vibrates at a frequency controlled by its own physical dimensions and the applied electric field. This frequency is then delivered to the user circuit, where it can be made available as an output signal.

The oscillator performs this operation in three stages. First, it amplifies the electrical field in order to set the crystal vibrating at its resonant frequency. The second stage is the feedback stage, in which the oscillator monitors the crystal’s output and adjusts the field as needed to maintain a stable frequency. Finally, the last stage is the output stage, in which the oscillator provides a stable frequency signal to the user circuit.

The 402F4001XIKR has a high stability of ±10 ppm at a temperature range of -55 to +130°C, and its startup time is fast. As such, it can be used for a variety of precise timing applications, from clocks and watches to audio systems and telecommunications.
