Description and Introduction

1.3 GHz bidirectional I2C-bus controlled synthesizer The TSA5514AT is a PLL (Phase-Locked Loop) frequency synthesizer IC manufactured by Philips (now NXP Semiconductors). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer:** Philips (NXP Semiconductors)  

### **Specifications:**  
- **Frequency Range:** 1.3 GHz (typical)  
- **Supply Voltage:** 4.5 V to 5.5 V  
- **Current Consumption:** 10 mA (typical)  
- **Programmable Divider Ratio:** 15-bit (N) + 7-bit (A)  
- **Reference Frequency:** Up to 8 MHz  
- **Serial Interface:** I²C-bus compatible (400 kHz max)  
- **Lock Detect Output:** Available  
- **Package:** SO16 (Small Outline 16-pin)  

### **Descriptions:**  
- The TSA5514AT is a low-power frequency synthesizer designed for RF tuning applications, such as TV tuners and satellite receivers.  
- It integrates a programmable divider, phase detector, and charge pump for PLL-based frequency synthesis.  
- The device supports I²C control for easy programming of frequency settings.  

### **Features:**  
- **Wide Frequency Coverage:** Suitable for high-frequency RF applications.  
- **Low Power Consumption:** Optimized for battery-powered or energy-efficient designs.  
- **I²C Control Interface:** Allows simple microprocessor-based tuning.  
- **Integrated Charge Pump:** Reduces external component count.  
- **Lock Detection:** Provides feedback for system synchronization.  

This information is based solely on the manufacturer's datasheet and technical documentation.
