Description and Introduction

Dual PLLs for 46/49 MHz Cordless Telephones The MC145168DW is a frequency synthesizer integrated circuit (IC) manufactured by Motorola. Below are its key specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Manufacturer:** Motorola  
- **Type:** Frequency Synthesizer IC  
- **Package:** SOIC-16 (DW suffix indicates the package type)  
- **Operating Voltage:** 3V to 9V (typical)  
- **Frequency Range:** Supports RF and VHF applications (exact range depends on external components)  
- **Phase Detector Type:** Digital phase/frequency detector  
- **Reference Oscillator:** On-chip, requires external crystal or clock input  
- **Programmable Divider:** Dual-modulus prescaler (e.g., 64/65 or 128/129)  
- **Lock Detect Output:** Indicates phase-locked condition  

### **Descriptions:**  
The MC145168DW is a CMOS-based PLL (Phase-Locked Loop) frequency synthesizer designed for communication systems, RF applications, and frequency generation. It integrates a reference oscillator, phase detector, and programmable dividers to generate stable output frequencies.  

### **Features:**  
- **Low Power Consumption:** CMOS technology ensures efficient operation.  
- **Digital Phase Detector:** Provides precise frequency control.  
- **Programmable Counters:** Allows flexible frequency division ratios.  
- **Wide Operating Voltage:** Supports 3V to 9V, making it versatile for different designs.  
- **Lock Detect Function:** Output signal indicates when the PLL is locked.  
- **Compact Package:** SOIC-16 form factor for space-constrained applications.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application circuits, refer to the official Motorola datasheet.
