402F240XXCAT devices are semiconductor crystals manufactured by Semtech which are tailored for a vast array of electronic applications. These crystals are typically used in digital circuits, including in digital signal processing, BLDC motor control, in digital audio converters, sound cards, digital cameras and consumer electronic products.

The 402F240XXCAT design is based on a two-electrode cantilever principle. This approach utilizes two capacitively-coupled and resistively-loaded electrodes at each end of the crystal device. This configuration facilitates elimination of the mechanical stress generated by the driving and damping signals applied to the crystal. By doing this, the device is able to achieve limited temperature stability and dynamic stability.

The primary function of the 402F240XXCAT crystal is the conduction of oscillatory signals with a frequency determined by the physical parameters of the device. In a typical 402F240XXCAT device, a athermal oscillator is formed between the two electrodes, producing a stable capacitance of around 30 pF. The frequency of the oscillatory wave is then determined by the capacitance and parallel chip resistor. This oscillatory wave also acts to drive the crystal output, amplifying the oscillation to a nominal level of around 500 mV.

The output waveform of the 402F240XXCAT device is a sine wave with a high frequency stability over temperature and voltage variations. This feature makes the device ideal for precision digital circuits, as it is able to provide consistent wave output over a wide range of temperatures and conditions. Furthermore, the device has a low power consumption, facilitating extended battery life for portable devices.
