Working Principle

A crystal is an oscillator circuit which produces a periodic, relatively accurate, stable frequency that can be used as a clock source for digital circuits. It typically consists of a quartz crystal and capacitors. When voltage is applied, the quartz crystal begins to vibrate at a particular frequency. The 416F24022AAR is a stable crystal with a shunt capacitance of 8.0pF, series resistor of more than 3000Ω, and frequency load capacitance 12.5pF. This enables the crystal to be used at a high frequency of up to 240MHz.

When the crystal unit oscillates, it is capacitively loaded by external circuitry. Generally, this external circuitry is a parallel combination of the tuning capacitor in the tank circuit and the internal shunt capacitance of the crystal itself. The crystal oscillates with a frequency determined by the the internal shunt and series capacitances, as well as the series resistor, which generally determine the “Q” (or quality factor) of the oscillator. This combination is known as the electromechanical resonance of the crystal and is used in crystal oscillators.

The 416F24022AAR is designed to be used as a library for fundamental mode for SMD type crystals ensuring high frequency and trouble-free operation. To ensure its accuracy, the 416F24022AAR is designed to guarantee frequency tolerance at ±20ppm, making it an ideal choice for a variety of RF applications.

Conclusion

The 416F24022AAR crystal unit is a versatile, durable and stable product that has a wide range of applications. With its series resistor, frequency load capacitance and shunt capacitance, it can be used in a wide range of digital, analog and RF devices for frequency control.
