Description and Introduction

1.3 GHz universal bus-controlled TV synthesizer The TSA5521T is a PLL (Phase-Locked Loop) frequency synthesizer IC manufactured by PHILIPS (now NXP Semiconductors). Below are its key specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Frequency Range:** 1.1 GHz to 2.1 GHz (typical operating range).  
- **Supply Voltage:** 2.7V to 5.5V (wide operating range).  
- **Current Consumption:** Typically 5 mA (low power consumption).  
- **Programmable Divider Ratio:** Allows flexible frequency synthesis.  
- **Phase Detector Frequency:** Up to 8 MHz (high-speed operation).  
- **Package Type:** SO16 (Small Outline 16-pin package).  

### **Descriptions:**  
- The TSA5521T is designed for RF frequency synthesis in applications such as tuners, set-top boxes, and communication systems.  
- It integrates a prescaler, phase detector, and charge pump for PLL-based frequency control.  
- Compatible with I²C bus interface for easy microcontroller programming.  

### **Features:**  
- **Wide Frequency Range:** Supports operation up to 2.1 GHz.  
- **Low Power Consumption:** Suitable for battery-powered devices.  
- **I²C Control Interface:** Simplifies integration with digital systems.  
- **High Integration:** Combines multiple PLL functions in a single IC.  
- **Low Phase Noise:** Ensures stable frequency synthesis for RF applications.  

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

Application Scenarios & Design Considerations

1.3 GHz universal bus-controlled TV synthesizer

Alternative Part Number

  • TDA5211 --: Single-chip FM/AM receiver IC with similar mixer/oscillator function and comparable supply voltage, commonly used as a substitute in tuner designs.
  • LM7001 --: PLL frequency synthesizer IC for radio tuners offering similar tuning control functionality and widely available as an alternative.
  • TEA5767 --: Integrated FM tuner IC with built-in PLL synthesizer, suitable replacement for tuner applications requiring similar functionality.
  • TDA6502 --: I2C-bus controlled TV tuner PLL synthesizer, functionally similar to the TSA5521 and from the same Philips/NXP lineage.
  • TDA5521T --: Same I2C-bus PLL synthesizer function and pinout, from the successor brand of Philips; direct functional replacement.
  • TDA5330T --: Similar TV tuning PLL synthesizer in the same family, usable when minor pin/software adjustments are acceptable.
  • TDA5500 --: Philips-family PLL synthesizer IC with similar architecture, usable as a functional substitute with minor circuit adaptation.
