Description and Introduction

2.5 GHz PLLatinum Ultra Low Power Frequency Synthesizer for RF Personal Communications The LMX2310USLDX is a PLLatinum™ Low Power Frequency Synthesizer manufactured by National Semiconductor (NSC).  

### **Key Specifications:**  
- **Frequency Range:** 550 MHz to 2.2 GHz  
- **Supply Voltage:** 2.7 V to 5.5 V  
- **Low Power Consumption:** Typically 4.5 mA at 3 V  
- **Phase Detector Frequency:** Up to 40 MHz  
- **Programmable Dual-Modulus Prescaler:** 8/9, 16/17, 32/33, 64/65  
- **Serial Interface:** 3-wire (SPI-compatible)  
- **Package:** 16-pin TSSOP  

### **Descriptions and Features:**  
- Designed for low-power wireless applications such as cordless phones, wireless LAN, and RF communication systems.  
- Integrated phase-locked loop (PLL) with a high-speed prescaler and phase-frequency detector (PFD).  
- Supports fractional-N and integer-N synthesis for flexible frequency generation.  
- On-chip reference oscillator with an external crystal.  
- Low phase noise and spurious performance.  
- Power-down mode for reduced current consumption when inactive.  

This synthesizer is optimized for battery-operated and portable applications requiring efficient frequency synthesis.
