FC4SDCBMF10.0-T1 application field and working principle

FC4SDCBMF10.0-T1 is a type of crystal, consisting of two layers of quartz. The index of refraction for both layers is different and the crystal is oriented in an off-axis orientation. As a result, it has an eye pattern that allows for fast frequency transitions, allowing for high frequency stability and excellent jitter rejection. In effect, it acts as an electrical filter, enabling the radio frequency signal to be transmitted with greater accuracy, stability, and fidelity.

Application field

Due to its excellent frequency stability, FC4SDCBMF10.0-T1 crystals are used for applications such as oscillator circuits, frequency divider or multiplier circuits, filters, and stabilization circuits. In particular, FC4SDCBMF10.0-T1 is a popular choice for resonator and transmitter circuits, as well as frequency synthesisers.

It is also used in a number of industrial and medical applications, where precision timing is essential. These include seismology, advanced data transmission, and GPS navigation. Additionally, due to its robustness and low power consumption, it is used in ultra-low temperature applications.

Working Principle

The FC4SDCBMF10.0-T1 crystal works by maintaining a resonating frequency. To maintain this frequency, an oscillating circuit is used to drive the crystal and provide the energy necessary to maintain a stable frequency. This oscillating circuit is known as an oscillator circuit.

The oscillator circuit works by using a feedback loop to detect when the frequency begins to drift, and then reintroduce energy to bring it back to the desired frequency. This feedback loop is known as the loop gain, and it is this loop gain that determines the crystal’s frequency stability.

Aside from the loop gain, factors such as the environment, temperature and damping can also affect the crystal’s frequency stability. To ensure optimal frequency stability, it is important to reduce unwanted vibrations, eliminate external interferences, and choose the correct parameters for the circuit.
