Description and Introduction

1.3 GHz Bidirectional I2C-bus controlled synthesizer The TSA5512AT is a PLL (Phase-Locked Loop) frequency synthesizer IC manufactured by NXP Semiconductors. Below are its specifications, descriptions, and features based on factual data:

### **Manufacturer:**  
NXP Semiconductors  

### **Description:**  
The TSA5512AT is a low-power frequency synthesizer designed for TV and VCR tuning applications. It integrates a programmable divider, phase detector, and charge pump, making it suitable for generating stable local oscillator signals in RF systems.  

### **Key Features:**  
1. **Frequency Range:**  
   - Operates up to **1.3 GHz** (typical).  

2. **Programmable Divider:**  
   - 15-bit programmable divider for flexible frequency synthesis.  

3. **Interface:**  
   - **I²C-bus** serial interface for control and programming.  

4. **Power Supply:**  
   - **Single +5V supply** operation.  

5. **Low Power Consumption:**  
   - Optimized for low-power applications.  

6. **Phase Detector & Charge Pump:**  
   - Built-in phase detector and charge pump for PLL operation.  

7. **Package:**  
   - **SO16 (Small Outline 16-pin)** package.  

8. **Applications:**  
   - TV tuners  
   - VCR tuning systems  
   - RF frequency synthesis  

### **Additional Notes:**  
- The TSA5512AT is designed for compatibility with **NXP’s tuner ICs** and related RF systems.  
- It supports **crystal or external reference oscillator** inputs.  

For detailed electrical characteristics and timing diagrams, refer to the official **NXP datasheet**.
