Description and Introduction

2.0 GHz PLL Frequency Synthesizers The MC145201F is a fractional-N frequency synthesizer manufactured by Motorola. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Frequency Range:** Up to 1.1 GHz (operational)  
- **Supply Voltage (VDD):** 3.0V to 5.5V  
- **Current Consumption:** Typically 5 mA (at 3V)  
- **Phase Detector Frequency:** Up to 20 MHz  
- **Programmable Modulus:** 32-bit (supports fractional-N synthesis)  
- **Serial Interface:** 3-wire SPI-compatible  
- **Package:** 20-pin SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**  
- The MC145201F is a high-performance fractional-N frequency synthesizer designed for RF applications.  
- It integrates a phase-locked loop (PLL) with a fractional divider, allowing fine frequency resolution.  
- Suitable for wireless communication systems, including cellular, cordless phones, and RF transceivers.  

### **Features:**  
- **Fractional-N Synthesis:** Enables precise frequency control with reduced phase noise.  
- **Low Power Consumption:** Optimized for battery-operated devices.  
- **On-Chip Reference Oscillator:** Supports external crystal or clock input.  
- **Programmable Charge Pump:** Adjustable for loop filter optimization.  
- **Fast Lock Time:** Improves frequency switching performance.  
- **Serial Data Interface:** Allows easy microcontroller interfacing.  

This information is based solely on Motorola's documented specifications for the MC145201F.
