The crystal is able to hold data reliably, without the need for frequent refreshes, resulting in more efficient storage.

Working Principle

The 402F54033CDR crystal is a type of Digital Resonator (DFR) that works by creating and controlling the frequency of an oscillator in a digital circuit. When the oscillator is turned on, the crystal will oscillate at a set frequency, and it will continue to oscillate until the oscillator is turned off. The frequency of the oscillator is determined by the properties of the crystal and its physical size, as well as other factors.

When the oscillator is turned on, the crystal will begin to vibrate at its resonance frequency, which is determined by several characteristics of the crystal. The first is its mass, which is determined by its physical size. The second is its stiffness, or dielectric constant, which is related to the material used to construct the crystal. Finally, the third characteristic is the load capacitance, which is determined by the capacitors connected to the crystal.

Once the oscillator is turned on, it will oscillate at the frequency determined by these factors. The signal produced by the oscillator can be further amplified by other electronic components to create a signal of a particular frequency, which can then be used by the device for a variety of tasks.
