They are also used in RF systems for communication to generate stable frequencies that are used for data transmission.

Working Principle

At the core of the SIT8918BE-73-33E-25.000000G is a temperature-compensated crystal oscillator or TCXO. This type of oscillator utilizes a quartz crystal to maintain a stable oscillating frequency. The oscillator is composed of an amplifier and a quartz resonator, and the frequency is determined by the mechanical properties of the quartz crystal. The amplitude of the output is modulated by the amplifier. In order to maintain a highly accurate oscillating frequency, the oscillator takes input from a temperature sensor, which is used to make adjustments to the frequency of the oscillator due to the effects of temperature. This makes the SIT8918BE-73-33E-25.000000G an ideal oscillator for applications that require high levels of accuracy and stability.
