Description and Introduction

Serial Input PLL Frequency Synthesizer with Analog Phase Detector (revA) The MC145159 is a CMOS integrated circuit manufactured by Motorola (MOTO). It is a PLL (Phase-Locked Loop) frequency synthesizer designed for applications requiring stable frequency generation, such as communication systems and signal processing.  

### **Key Features:**  
- **Frequency Range:** Supports operation in the VHF and UHF bands.  
- **Programmable Divider:** Includes a 15-bit programmable reference divider and a 12-bit programmable N-divider.  
- **Serial Data Interface:** Uses a 3-wire serial interface (data, clock, enable) for programming.  
- **Low Power Consumption:** CMOS technology ensures efficient power usage.  
- **Supply Voltage:** Typically operates at **5V DC**.  
- **Package Options:** Available in **DIP (Dual In-line Package)** and **SOIC (Small Outline IC)** formats.  
- **Phase Detector:** Includes a digital phase detector for stable frequency locking.  

### **Applications:**  
- RF communications (transmitters/receivers)  
- Frequency modulation/demodulation  
- Signal generators  
- Wireless systems  

### **Manufacturer Specifications:**  
- **Manufacturer:** Motorola (MOTO)  
- **Technology:** CMOS  
- **Operating Temperature Range:** Typically **-40°C to +85°C**  

This device is primarily used in frequency synthesis applications where precise and programmable frequency control is required.
