FA-238 33.3300MA20W-W3

Crystals are materials composed of atoms, molecules or ions arranged in an orderly, three-dimensional pattern. They are often used in circuits as they exhibit a certain frequency or slew rate and can be used to detect and transmit information. One type of crystal that is used in circuits is the FA-238 33.3300MA20W-W3 crystal. This article will provide an overview of its application field and working principle.

Application Field

FA-238 33.3300MA20W-W3 crystals are primarily used in clock oscillator circuits, both digital and analog. The clock oscillator’s output is either a predetermined voltage or frequency, or a combination of both. The circuit needs an oscillator to maintain its clock signal, and the frequency of the crystal determines the frequency of the oscillator’s output. Consequently, the circuit’s timing accuracy and output stability depend upon the crystal.

FA-238 33.3300MA20W-W3 crystals are most commonly used in telecommunications, instrumentation, and embedded systems applications, as they are extremely accurate and stable. Furthermore, they can withstand wide temperature ranges (−40 to 85°C), and they are also vibration and shock resistant. This makes them ideal for environments where temperatures vary often and/or where shock and vibration are present, such as automotive and industrial applications.

Working Principle

Crystals use the piezoelectric effect. This effect is when a material, such as quartz, is subjected to an alternating voltage, it changes its shape. Conversely, when a material is subjected to an alternating current, it creates an alternating voltage. As a result, when the quartz crystal within the FA-238 33.3300MA20W-W3 is connected to a variable voltage source, it vibrates at a frequency that is dependent on the voltage applied.

The voltage source is typically an external oscillator circuit. As the voltage changes, the crystal’s shape changes, resulting in a change in frequency. The crystal’s maximum frequency is determined by its dimensions. As the voltage changes, so does the crystal’s frequency, and this is known as its modulation frequency. The frequency at which the crystal oscillates is known as its operating frequency.

When the FA-238 33.3300MA20W-W3 is placed in a circuit, it generates an oscillating signal, which is then applied to the other components in the circuit. This signal may be used as the clock signal to control timing in the circuit, or it may be used to generate signals of other frequencies, depending upon what type of circuit is being used.

Conclusion

FA-238 33.3300MA20W-W3 crystals are primarily used in telecommunication, instrumentation and embedded systems applications. The crystal oscillates with a frequency determined by the voltage applied to it, using the piezoelectric effect. This oscillating signal is then applied to the rest of the circuit, typically serving as the clock signal and determining the timing of the circuit. As such, it is very important to choose the right crystal to ensure an accurate and stable clock signal.
