Working Principles

The working principle of CD4046BNSRE4 involves the following steps: 1. The input reference signal is compared with the feedback signal using the phase comparator. 2. The phase comparator generates an error signal based on the phase and frequency difference between the two signals. 3. The error signal is filtered by the low-pass filter to remove high-frequency noise. 4. The filtered signal controls the voltage-controlled oscillator, adjusting its frequency and phase to match the input reference signal. 5. The lock indicator provides a visual indication when the PLL is locked.
