Product Overview: NXP 74HCT4046AD Phase-Locked Loop (PLL)

The NXP 74HCT4046AD is a high-speed Si-gate CMOS device that is part of the 74HC/HCT family. This integrated circuit is a phase-locked loop (PLL) that includes a linear Voltage-Controlled Oscillator (VCO) and two different phase comparators (PC1 and PC2) with a common signal input amplifier and a common comparator input. The 74HCT4046AD is designed to operate from a 5 V supply, making it suitable for interfacing with TTL levels.

Key Features

• Voltage-Controlled Oscillator (VCO): The VCO provides a highly stable output frequency that is linearly proportional to the input voltage applied to the VCOIN pin.
• Phase Comparators: Two phase comparators are included, each with different characteristics. PC1 is a balanced type that provides a frequency difference output, while PC2 is an edge-controlled digital memory network.
• Input Frequency Range: The IC is capable of handling a wide range of input frequencies, making it versatile for various applications.
• Supply Voltage: It operates at a nominal supply voltage of 5 V, compatible with TTL systems.
• Low Power Consumption: The device is designed for low power consumption, which is critical for battery-operated and power-sensitive applications.
