Description and Introduction

Phase Locked Loop The MC14046BCL is a Phase-Locked Loop (PLL) integrated circuit manufactured by Motorola (MOT).  

### **Key Specifications:**  
- **Type:** CMOS Phase-Locked Loop (PLL)  
- **Supply Voltage Range:** 3V to 18V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package:** Ceramic Leadless Chip Carrier (LCC)  
- **Frequency Range:** Suitable for low to moderate frequency applications  

### **Descriptions and Features:**  
- **Phase Comparator Options:** Includes two phase comparators (PC1 and PC2) with different characteristics.  
  - **PC1:** Provides a digital error signal and a lock indication.  
  - **PC2:** Offers a linear error signal without lock indication.  
- **Voltage-Controlled Oscillator (VCO):** Features a wide frequency range controlled by external resistors and capacitors.  
- **Low Power Consumption:** Typical of CMOS technology, making it suitable for battery-operated devices.  
- **High Noise Immunity:** Due to CMOS construction.  
- **Zener Diode Protection:** Helps protect against electrostatic discharge (ESD).  
- **Applications:** Used in frequency modulation (FM), demodulation, tone decoding, frequency synthesis, and signal conditioning.  

This IC is part of the Motorola 4000B series, known for reliability in industrial and military applications.

Application Scenarios & Design Considerations

Phase Locked Loop

Alternative Part Number

  • CD4046BE --: Direct functional equivalent phase-locked loop IC in the 4000 series, widely available and pin-compatible with the MC14046.
  • HEF4046BP --: Standard 4046 PLL device from the HEF series, same function and pinout, suitable drop-in replacement.
  • MC74HC4046AN --: CMOS PLL with equivalent 4046 functionality, different series naming and good availability as an alternative.
