### **Descriptions:**  
The LMX2604LQ is a wideband RF synthesizer with an integrated VCO, designed for high-performance applications requiring low phase noise and low spurious content. It supports fractional-N and integer-N modes for flexible frequency synthesis.  

### **Features:**  
- **Ultra-Low Phase Noise** for high-performance RF applications  
- **Wide Frequency Coverage** (47 MHz to 5.9 GHz)  
- **Low Power Consumption**  
- **Integrated VCO Eliminates External Components**  
- **Fast Frequency Switching**  
- **SPI Programmable Interface**  
- **Robust Lock Detection**  
- **Small Footprint QFN Package**  

This synthesizer is commonly used in wireless infrastructure, test equipment, and broadband communication systems.  

*(Note: "NS" typically refers to National Semiconductor, which was acquired by Texas Instruments in 2011. The LMX2604LQ is now part of TI's product lineup.)*
