ON Semiconductor MC14046B Phase Locked Loop

The MC14046B is a versatile phase-locked loop (PLL) circuit that has been designed and manufactured by ON Semiconductor. This integrated circuit is part of the high-performance silicon-gate CMOS range and is widely used in a variety of applications, including frequency synthesis and modulation, frequency discrimination, and tone decoding.

The device comprises a linear voltage-controlled oscillator (VCO), two phase comparators (PC1 and PC2), a zener diode, a source follower, and a sink to ensure a wide range of applications are covered. The VCO frequency is determined by external components (resistor and capacitor), and it can be accessed by the user through the VCO OUT pin. The VCO is designed to cover a wide frequency range, making the MC14046B suitable for numerous applications.

Phase Comparator I is an exclusive-OR (XOR) network that provides a frequency and phase comparison between signals on the SIG IN and COMP IN inputs. Phase Comparator II is a more complex network that provides a narrow pulse when the SIG IN signal leads the COMP IN signal, and a wide pulse when lagging. These features make the MC14046B an excellent choice for applications requiring precise phase or frequency matching.

The MC14046B operates over a wide voltage range from 3V to 18V and features a low stand-by current, making it ideal for battery-operated equipment. The device is available in different package types including DIP and SOIC, providing flexibility in design for PCB layout and space constraints.

With its robust design and ON Semiconductor's commitment to quality, the MC14046B PLL circuit is a reliable component for engineers looking to implement a phase-locked loop in their designs. Whether it's for signal processing, communications, or control systems, the MC14046B offers a high level of integration and performance that designers can count on.
