Description and Introduction

1.2 GHz/600 MHz PLLatinum Low Power Dual Frequency Synthesizer for RF Personal Communications The LMX2332UTMX is a dual PLL (Phase-Locked Loop) frequency synthesizer manufactured by National Semiconductor (NSC).  

### **Key Specifications:**  
- **Frequency Range:**  
  - PLL1: 1.2 GHz  
  - PLL2: 550 MHz  
- **Supply Voltage:** 2.7V to 5.5V  
- **Low Power Consumption:** Typically 5 mA (at 3V)  
- **Package:** 16-pin TSSOP  
- **Serial Interface:** 3-wire (data, clock, enable)  
- **Reference Input Frequency:** Up to 50 MHz  
- **Programmable Charge Pump Currents**  

### **Descriptions and Features:**  
- Dual PLL architecture for flexible frequency synthesis.  
- Integrated phase detectors and charge pumps.  
- Supports fractional-N and integer-N modes (PLL2 only).  
- Low phase noise and spurious performance.  
- Power-down mode for reduced current consumption.  
- Compatible with common microcontrollers via serial interface.  

This device is commonly used in wireless communication systems, RF transceivers, and other frequency synthesis applications.
