Working Principles

The SN74LV4046ADGVR operates based on the principles of phase-locked loop (PLL) and voltage-controlled oscillator (VCO). The PLL compares the phase and frequency of the reference signal (REF) with the VCO output (VCO), adjusting the control voltage (VIN) to maintain synchronization. The VCO generates an output frequency proportional to the control voltage, which can be precisely controlled using external components. The lock detect output (LD) indicates whether the PLL is locked to the reference frequency or not.
