Working Principle

The HCM4910000000ABJT crystal consists of a quartz crystal and a metal package. The quartz crystal is cut and shaped to produce a strong resonance at a particular frequency, typically +/-20 parts per million (ppm). At resonance, the quartz crystal will vibrate at a specific frequency and create an oscillation.

The metal package covers the quartz crystal and contains a tuning capacitance and other components. These components are used to control and modify the oscillation frequency. The tuning capacitance is used to tune the frequency of the crystal and can be changed by adjusting the amount of charge stored in the capacitor. This adjustment is typically done by the manufacturer.

The oscillator circuit amplifies the signal from the quartz crystal. The amplification is necessary to produce a strong signal that can be used in communication systems. The amplified signal is then shifted in frequency and coupled to other circuit components, such as filters and frequency dividers, to produce the desired output frequency.

The HCM4910000000ABJT crystal is used to provide accurate and low jitter frequency sources for radio and television transmitters, communication systems, and other applications. It can be used for frequency synthesis, phase-locked loops (PLLs), time basis and clock generator systems, and is available in a variety of package sizes and configurations.

The HCM4910000000ABJT crystal is an excellent choice for applications requiring precision timekeeping and synchronization.
