It is specifically designed for use in WiFi applications and provides a stable source of clock reference for various devices. The 416F26023AST is also suitable for use in automotive electronic systems, Bluetooth and other wireless systems, radio telemetry, and frequency hopping control electronics.

The 416F26023AST is a miniature chip sized device, measuring only 1.5mm x 1.75mm x 1.1mm. It has a frequency stability of ±250ppm and operates with a low voltage of 1.8V. The device is permanently sealed in a moisture proof package and is resistant to environmental conditions like humidity, heat and shocks. Its high reliability makes it ideal for use in harsh environments.

Working Principle of 416F26023AST

The 416F26023AST consists of two main components—a piezoelectric resonator and an integrated circuit. The piezoelectric resonator is constructed from a thin slice of quartz or ceramic material to which electrodes are applied. These electrodes provide the electrical connections for the resonator. When an electric field is applied across the electrodes, the resonator vibrates at a specific frequency. This frequency is determined by the thickness and shape of the resonator.

The integrated circuit consists of an oscillator circuit and an amplifier. The oscillator circuit produces a periodic, an AC current at a specific frequency, while the amplifier amplifies the output of the oscillator circuit to drive the piezoelectric resonator. The resonator’s frequency is determined by the amplitude and shape of the AC current produced by the oscillator. The amplifier is used to further amplify the output of the oscillator circuit, thus providing a higher and more stable frequency.

The 416F26023AST ceramic resonator is an excellent choice for applications requiring high stability with low power consumption. It is ideal for use in harsh environmental applications such as automotive, industrial, or medical applications. It provides a stable source of clock reference and operates with a low voltage, making it suitable for use in a variety of devices.
