Description and Introduction

PLLatinum Low Power Dual Frequency Synthesizer for RF Personal Communications The LMX2331LSLB is a PLLatinum™ Low Power Dual Frequency Synthesizer manufactured by National Semiconductor. Here are the key specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** National Semiconductor  
- **Type:** Dual Frequency Synthesizer  
- **Technology:** PLLatinum™ (Low Power, High Performance)  
- **Frequency Range:**  
  - RF Synthesizer: Up to 2.8 GHz  
  - IF Synthesizer: Up to 550 MHz  
- **Supply Voltage:** 2.7V to 5.5V  
- **Current Consumption:** Low power operation (typical 5 mA in active mode)  
- **Package:** 20-pin TSSOP (Thin Shrink Small Outline Package)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The LMX2331LSLB is designed for wireless communication applications, supporting both RF and IF frequency synthesis.  
- It integrates two high-performance phase-locked loops (PLLs) with low phase noise and fast switching speeds.  
- The device is optimized for battery-powered systems due to its low power consumption.  

### **Features:**
- **Dual PLL Architecture:** Independent RF and IF synthesizers in a single chip.  
- **Low Phase Noise:** Ensures high signal integrity for wireless applications.  
- **Wide Supply Voltage Range:** Compatible with 3V and 5V systems.  
- **Serial Interface:** 3-wire SPI-compatible control for easy programming.  
- **Hardware and Software Power-Down Modes:** Reduces power consumption when inactive.  
- **Integrated Prescalers:** Supports both integer-N and fractional-N modes.
