Description and Introduction

1.1 GHz PLL Frequency Synthesizers The MC145190F is a PLL (Phase-Locked Loop) frequency synthesizer manufactured by Motorola. Below are the key specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Frequency Range:** Up to 2.1 GHz (with external prescaler)  
- **Supply Voltage:** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 16-pin SOIC (Small Outline Integrated Circuit)  
- **Reference Oscillator Input:** Supports crystal or external reference  
- **Serial Interface:** 3-wire SPI (Serial Peripheral Interface) compatible  

### **Descriptions:**  
- The MC145190F is a fractional-N PLL synthesizer designed for high-frequency RF applications.  
- It integrates a phase detector, reference divider, fractional-N divider, and control logic.  
- Suitable for wireless communication systems, including cellular, cordless phones, and RF transceivers.  
- Supports fractional-N synthesis for improved frequency resolution and reduced phase noise.  

### **Features:**  
- **Fractional-N Division:** Enables fine frequency steps with low spurious noise.  
- **Programmable Dividers:** Reference and fractional-N dividers are software-configurable.  
- **Low Power Consumption:** Optimized for battery-operated devices.  
- **Fast Lock Time:** Enhanced switching speed for frequency hopping applications.  
- **Integrated Phase Detector:** Reduces external component count.  
- **Serial Data Interface:** Allows easy microcontroller interfacing.  

This information is based solely on the manufacturer's datasheet for the MC145190F.
