Working Principle of DSC400-4111Q0112KE1

The DSC400-4111Q0112KE1 crystal oscillator uses a temperature-compensated quartz crystal resonator as its main oscillating element, being a so-called AT-cut crystal resonator. It utilizes a basic quartz crystal resonator to generate a stable frequency. This crystal resonator is driven by its own series resonance principle, that is, when an appropriate electrical excitation is applied to it, an output signal of a certain frequency is generated. The frequency of the output signal is related to the mechanical properties of the crystal, which is determined by the quartz crystal’s physical size, shape and mass. This frequency is also very dependent on the temperature, thus a temperature compensation circuit is needed to maintain a stable output frequency.

The crystal resonator of the DSC400-4111Q0112KE1 is driven by its own series resonance circuit, which is composed of an oscillator, frequency divider and buffer amplifier. The oscillator contains a quartz crystal resonator and its connected electronic circuit, mainly formed by a number of capacitors, inductors and other passive components. The oscillator circuit generates a periodic electrical signal which is then passed to the frequency divider, which can be used to divide the output frequency into different frequency outputs. Finally, the divided signals are processed by the buffer amplifier, which provides a very stable output signal.
