CD4046BD

The CD4046BD is a CMOS phase-locked loop (PLL) IC consisting of a linear voltage-controlled oscillator (VCO) and two different phase comparators with a common signal input amplifier and a common comparator input. The PLL is capable of frequency synthesis and modulation/demodulation, making it suitable for various communication and control applications. It operates over a wide voltage range and provides high noise immunity.
