Description and Introduction

PLLatinum⑩ Low Power Dual Frequency Synthesizer for RF Personal Communications The LMX2335LM is a PLLatinum™ Low Power Dual Frequency Synthesizer manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Frequency Range:**  
  - RF Synthesizer: 1100 MHz to 2200 MHz  
  - IF Synthesizer: 400 MHz to 800 MHz  
- **Supply Voltage:** 2.7V to 5.5V  
- **Low Power Consumption:**  
  - Typically 4.5 mA (RF section)  
  - Typically 3.5 mA (IF section)  
- **Phase Detector Frequency:** Up to 40 MHz  
- **Programmable Charge Pump Current:** Adjustable from 0.4 mA to 5 mA  
- **Serial Interface:** 3-wire SPI-compatible  
- **Package:** 16-pin TSSOP  

### **Descriptions and Features:**  
- **Dual PLL Architecture:** Contains two independent phase-locked loops (RF and IF) for frequency synthesis.  
- **Low Phase Noise:** Optimized for wireless communication applications.  
- **Integrated Prescalers:**  
  - RF: Dual-modulus (8/9, 16/17, 32/33, 64/65)  
  - IF: Single-modulus (64/65)  
- **Hardware and Software Power-Down Modes:** Reduces power consumption when not in use.  
- **Wide Operating Temperature Range:** -40°C to +85°C.  
- **Applications:** Wireless handsets, cordless phones, satellite receivers, and other RF communication systems.  

This device is designed for high-performance frequency synthesis with low power consumption, making it suitable for portable and battery-operated applications.
