Crystals are widely used in electronics, due to their piezoelectric properties and ability to accurately transform electrical signals into sound or vice versa. FA-128 48.000000M-70689N22R3 is a crystal that is often used in applications in order to provide a steady frequency. Broadly speaking, the application field and working principle of this crystal can be broken down into four distinct parts: crystal structure and frequency stability, oscillator circuit, external circuitry and calibration.

Crystal Structure and Frequency Stability
The basic structure of FA-128 48.000000M-70689N22R3 is formed by a crystal substrate combined with an electrode. This substrate, commonly referred to as the quartz crystal, is made of quartz with a small trace of ferric oxide, which adds electrical and mechanical strength. Its remarkable piezoelectricity allows it to respond to an electric charge by vibrating at a fixed frequency. This vibration is then used to generate a steady frequency output.

The frequency stability of the crystal is determined by the cut, shape and size of the quartz. FA-128 48.000000M-70689N22R3 is cut in the AT-cut shape and is exceptionally stable. This ensures that its frequency output remains constant and reliable, even when the environment is causing electrical interference. The crystal is hermetically sealed in a silver can to prevent oxidation and other environmental changes from affecting its vibration.

Oscillator Circuit
In order to get the crystal to generate a frequency output, an oscillator circuit must be connected to it. The type of circuit used will depend on the type of application; for example, a sinewave oscillator is used for general timing applications, while a Pierce oscillator is used in RF systems. The oscillator circuit supplies the crystal with a small AC voltage, which causes it to vibrate at the crystal\'s resonant frequency.

External Circuitry
In order to make use of the frequency output generated by the oscillator circuit and crystal, an external circuitry must be connected to it. This circuitry is designed to convert the signal into a form that can be utilized by other components. For example, it could be a filter circuit that removes any unwanted frequencies or a voltage amplifier that increases the level of a signal. Other external circuitry can also be used to enhance the signal output of the crystal.

Calibration
The last step in the application field and working principle of FA-128 48.000000M-70689N22R3 is calibration. Calibration is the process of adjusting the frequency output of the crystal to the desired level. This is important, as the frequency output must remain constant in order for the crystal to be effective. It is critical to ensure that the frequency output is stable before using the crystal in any application.

In conclusion, FA-128 48.000000M-70689N22R3 is a crystal that is often used in applications in order to provide a steady frequency. Its precise structure and piezoelectric properties enable it to transform electrical signals into sound or vice versa. An oscillator circuit is connected to the crystal to cause it to vibrate at its resonant frequency. External circuitry is then used to convert the signal, and calibration is necessary in order to maintain a stable frequency output. All of these factors form the application field and working principle of FA-128 48.000000M-70689N22R3.
