Description and Introduction

Phase-locked-loop with lock detector The 74HCT7046AD is a phase-locked loop (PLL) integrated circuit manufactured by NXP Semiconductors (formerly Philips, hence "PHI"). It is designed for applications requiring frequency synthesis, demodulation, and clock recovery. Key specifications include:

- **Supply Voltage Range**: 4.5V to 5.5V
- **Operating Temperature Range**: -40°C to +125°C
- **Package**: SOIC-16
- **Logic Family**: HCT (High-speed CMOS with TTL compatibility)
- **Features**:
  - On-chip VCO (Voltage-Controlled Oscillator)
  - Phase comparators with different characteristics
  - Low power consumption
  - High noise immunity
- **Applications**: Frequency synthesis, FM demodulation, tone decoding, and clock synchronization.

This information is based on the manufacturer's datasheet and technical documentation.

Description and Introduction

Phase-locked-loop with lock detector The **74HCT7046AD** from Philips is a high-speed CMOS integrated circuit designed for phase-locked loop (PLL) applications. Combining a phase comparator, voltage-controlled oscillator (VCO), and amplifier, this versatile component is widely used in frequency synthesis, clock recovery, and modulation/demodulation circuits.  

Built with HCT technology, the 74HCT7046AD ensures compatibility with both TTL and CMOS logic levels while maintaining low power consumption. Its three-phase comparator options—PC1, PC2, and PC3—provide flexibility for different synchronization requirements, making it suitable for precision timing applications. The integrated VCO offers a wide frequency range, adjustable via external resistors and capacitors.  

Key features include high noise immunity, stable operation across a supply voltage range of 4.5V to 5.5V, and robust performance in industrial environments. The device is housed in a 16-pin SOIC package, ensuring compact integration into modern electronic designs.  

Engineers favor the 74HCT7046AD for its reliability in communication systems, data synchronization, and signal conditioning. Its balanced performance and ease of use make it a preferred choice for both prototyping and production applications where precise phase and frequency control are critical.
