FC4SDCBMF3.6864-T1 Application Field and Working Principle

FC4SDCBMF3.6864-T1 is a type of crystal oscillator (XO) which is used in various electronic applications, especially in high-end electronic products. It is an integrated electronic device constructed of multiple components, including a quartz crystal, an amplifier, an oscillating circuit, and an external package. The quartz crystal is the fundamental element of oscillation, and is held by a shell or other housing to protect electrical contacts and supply lines. The amplifier is connected to the crystal to shape the waveform and provide additional power. The oscillating circuit, which produces the oscillation, is connected to the amplifier and the output of the oscillator may be AC or DC, depending on the frequency and application.

FC4SDCBMF3.6864-T1 crystals belong to the family of frequency-stabilized quartz crystals, and can be used in diverse industrial and consumer applications like clock synchronization and modulator circuits, cellular phones and other mobile applications, automotive systems, radio communication receivers and transmitters, switching power converters, satellite tracking systems, etc. The oscillator frequency has been precisely defined to ensure accurate timing performance, and its stability over temperature, load, voltage and other environmental conditions has been extensively tested.

The frequency of a quartz crystal is determined by the size and shape of its base metal structure. The frequency is determined by the grain structure of the metal, which is extremely precise and stable. The frequency can be adjusted by presenting electric signals to the unit, known as "oelectrometry". FC4SDCBMF3.6864-T1 is derived from this technique, and is an improved form of the basic concept with numerous advantages. It combines the best qualities of quartz and metal into one package and provides superior frequency control. Its components are enclosed in a hermetically-sealed package, significantly improving its reliability.

At the core of the FC4SDCBMF3.6864-T1 crystal is a quartz crystal resonator consisting of two identical quartz plates, one of which is held in tension. The tension causes vibrations to occur when the quartz is subjected to an alternating electric field, enabling it to excite its own oscillatory waveform – the resonance frequency. This is the fundamental frequency used by a quartz crystal oscillator in electronic devices. Depending on the application, it can be equipped with a quartz transducer, which helps in converting the mechanical wave of the quartz resonator into electrical signals.

The quartz resonator can be adjusted as per application specific requirements, either by changing the tension in the crystal or by switching between two resonators of different frequencies. Due to the excellent frequency stability and precision of FC4SDCBMF3.6864-T1, it is an ideal choice for applications relying heavily on precise timing, like satellite tracking systems, cellular phones, and radio communication receivers and transmitters.

Moreover, FC4SDCBMF3.6864-T1 is much less expensive compared to other types of oscillators, making it a favorite among cost-conscious buyers. Owing to its versatility, robust mechanical design and frequency stability, it is also a popular choice for industrial and military applications. In conclusion, FC4SDCBMF3.6864-T1 is a great choice for applications where precise timing is required and cost is a factor. Its excellent frequency stability and precise output make it a suitable option for numerous industrial, automotive, military, and consumer applications.
