Working Principle

The 653L7426A2T oscillator is based on a quartz resonator that is used to convert electrical signals into an exact frequency signal. The oscillator itself is based on a phase locked loop (PLL) system that is used to ensure the stability of the generated frequency and its accuracy. In the first part of the PLL, a quartz resonator is used to generate a reference signal. This signal is then converted into an analog voltage signal by a voltage controlled oscillator (VCO).

The VCO’s output is then compared with the frequency and amplitude of the reference signal in the phase detector (PD), producing an error signal for the PLL loop. The loop then adjusts the VCO frequency to match the reference signal, thus ensuring a stable output signal. The output signal is then filtered by a low pass filter to reduce noise and to ensure precise frequency control.

The 653L7426A2T oscillator is capable of producing a wide range of different frequencies depending on the specific application. This makes it ideal for various applications as it provides a high level of accuracy and versatility for different end products.
