The working principle of an oscillator is defined by the properties of its active components and the configuration of the circuit. In the case of the SIT8209AI-2F-25S-156.253906T oscillator, the active components are two quartz resonators: the primary tuning fork and the secondary scoring fork. The primary tuning fork is designed to generate the initial signal frequency and is used to determine the frequency accuracy and stability of the oscillator. The secondary scoring fork tunes the frequency range of the oscillator and is used to compensate for the losses and variations of the initial signal frequency.

The primary tuning fork is connected to the input of a standard operational amplifier (Op Amp). The output of the Op Amp is connected to the secondary scoring fork. The two forks are connected in parallel, forming an oscillator circuit that amplifies the in-phase signal wave so that the output frequency can be precisely controlled. The oscillator is then calibrated and adjusted to maintain a stable frequency and achieve the desired accuracy over temperature.

The frequency of a quartz oscillator is determined by the resonant frequency of the quartz tuning fork. The resonant frequency changes depending on the environment, such as temperature, pressure, and humidity. To maintain a stable frequency, the quartz oscillator must be calibrated and adjusted to compensate for any changes in the environment. The SIT8209AI-2F-25S-156.253906T oscillator is designed to be highly accurate and reliable, and thus, it is suitable for use in a wide range of applications that require precision timing.
