Description and Introduction

Serial-Input PLL Frequency Synthesizer with Aanalog Phase Detector The MC145159DW1 is a frequency synthesizer integrated circuit (IC) manufactured by Motorola. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Motorola  
- **Part Number:** MC145159DW1  
- **Type:** Frequency Synthesizer IC  
- **Package:** SOIC-16 (DW package)  
- **Operating Voltage:** 3V to 9V  
- **Frequency Range:** Supports programmable frequency synthesis  
- **Phase Detector Type:** Digital phase/frequency detector  
- **Reference Oscillator Input:** Crystal or external reference  
- **Programmable Divider:** Dual-modulus prescaler (e.g., 64/65, 128/129)  
- **Serial Interface:** SPI-compatible for control  

### **Descriptions:**
The MC145159DW1 is a CMOS-based PLL (Phase-Locked Loop) frequency synthesizer designed for RF and communication applications. It integrates a reference oscillator, phase detector, and programmable dividers to generate stable output frequencies. The IC is commonly used in radio transceivers, wireless systems, and other frequency-agile applications.

### **Features:**
- **Low Power Consumption:** CMOS technology ensures efficient operation.  
- **Wide Supply Voltage Range:** 3V to 9V for flexibility in design.  
- **Serial Data Input:** Allows easy microcontroller interfacing.  
- **Dual-Modulus Prescaler:** Enables high-frequency division ratios.  
- **Crystal Oscillator Interface:** Supports stable reference frequency generation.  
- **Phase Detector with Lock Detect:** Provides stable frequency locking.
