Description and Introduction

Serial-Input PLL Frequency Synthesizer The MC145155P2 is a CMOS LSI Frequency Synthesizer manufactured by Motorola (now ON Semiconductor).  

### **Key Features:**  
- **Frequency Range:** Operates up to several hundred MHz (exact range depends on external components).  
- **Programmable Divider:** Dual-modulus prescaler (e.g., 8/9, 32/33, or 64/65) for flexible frequency division.  
- **Serial Data Interface:** Allows microprocessor control via a 3-wire serial interface (Data, Clock, Enable).  
- **Phase Detector:** Includes a digital phase/frequency detector for stable PLL operation.  
- **Low Power Consumption:** CMOS technology ensures efficient power usage.  
- **Package:** 16-pin DIP (Dual In-line Package).  

### **Applications:**  
- Used in **radio communications, wireless systems, and frequency synthesis applications**.  
- Suitable for **VHF/UHF transceivers, FM/AM radios, and signal generators**.  

### **Manufacturer Specifications:**  
- **Supply Voltage:** 3V to 9V (typical 5V operation).  
- **Operating Temperature:** -40°C to +85°C.  
- **Phase Detector Output:** Digital (for driving charge pumps in PLL circuits).  

This IC is now considered **obsolete** but may still be available from secondary suppliers. For exact datasheet details, refer to the original Motorola documentation.
