Description and Introduction

1.3 GHz Bidirectional I2C-bus controlled synthesizer The TSA5512T is a PLL frequency synthesizer IC manufactured by PHILIPS (now NXP Semiconductors). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Frequency Range:** Up to 1.3 GHz  
- **Supply Voltage:** 4.5V to 5.5V  
- **Current Consumption:** Typically 10mA  
- **Programmable Divider Ratio:** 64 to 131,071  
- **Phase Comparator:** Digital, with lock detect  
- **Serial Interface:** I²C-bus compatible  

### **Descriptions:**  
- The TSA5512T is a low-power frequency synthesizer designed for RF tuning applications, such as TV tuners and satellite receivers.  
- It integrates a programmable divider, phase comparator, and charge pump for PLL-based frequency synthesis.  
- The device is controlled via an I²C interface, allowing easy integration with microcontrollers.  

### **Features:**  
- **Wide Frequency Range:** Supports operation up to 1.3 GHz.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **I²C Control:** Simplifies interfacing with digital systems.  
- **Lock Detect Function:** Provides feedback on PLL lock status.  
- **High Integration:** Combines multiple PLL functions in a single IC.  

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