Working Principles

The SN74LV4046ANSR operates based on the principles of voltage-controlled oscillation and phase-locked loops. The VCO generates an output frequency that is controlled by the control voltage applied to its input. The phase comparator compares the phase difference between the reference clock input and the VCO output, generating an error signal. This error signal is filtered by the loop filter and used to adjust the control voltage through the charge pump. The PLL locks the VCO frequency to the reference clock frequency, ensuring synchronization.
