Description and Introduction

Phase Locked Loop The MC14046B is a phase-locked loop (PLL) integrated circuit manufactured by ON Semiconductor.  

### **Specifications:**  
- **Supply Voltage Range:** 3V to 18V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Low Power Consumption:** Suitable for battery-operated applications  
- **High Noise Immunity:** CMOS technology provides robust performance  
- **Package Options:** PDIP-16, SOIC-16  

### **Descriptions:**  
The MC14046B is a CMOS-based PLL IC that includes a voltage-controlled oscillator (VCO), phase comparator, and source follower. It is designed for frequency synthesis, demodulation, and clock synchronization applications.  

### **Features:**  
- **Dual Phase Comparators:**  
  - **PC1 (Exclusive-OR Gate):** Provides a digital phase comparison.  
  - **PC2 (Edge-Triggered JK Flip-Flop):** Offers better noise rejection.  
- **Voltage-Controlled Oscillator (VCO):** Wide frequency range controlled by external components.  
- **Zener Diode:** Provides a stable reference voltage for the VCO.  
- **Source Follower Output:** Buffers the VCO input for stable operation.  
- **High Input Impedance:** Minimizes loading effects on external circuits.  

This IC is commonly used in communication systems, tone decoders, and frequency modulation/demodulation circuits.
