Description and Introduction

1.3 GHz universal bus-controlled TV synthesizers The TSA5526AM 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:** 3 MHz to 1.3 GHz  
- **Supply Voltage:** 4.5 V to 5.5 V  
- **Current Consumption:** Typically 10 mA  
- **Programmable Divider Ratio:** 64 to 131,071  
- **Phase Comparator Frequency:** Up to 8 MHz  
- **Lock Detect Output:** Available  
- **Package:** SO20 (20-pin Small Outline Package)  

### **Descriptions:**  
- The TSA5526AM is designed for RF frequency synthesis in applications such as TV tuners, satellite receivers, and communication systems.  
- It integrates a programmable divider, phase comparator, and charge pump for PLL-based frequency control.  
- Operates with a single 5V supply and supports serial (I²C) interface for programming.  

### **Features:**  
- **Wide Frequency Range:** Covers 3 MHz to 1.3 GHz.  
- **Low Power Consumption:** Typically 10 mA at 5V.  
- **Serial Control Interface:** I²C-bus compatible for easy microcontroller interfacing.  
- **High-Speed Phase Comparator:** Supports up to 8 MHz.  
- **Integrated Charge Pump:** For loop filter compatibility.  
- **Lock Detect Function:** Indicates PLL lock status.  

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

Application Scenarios & Design Considerations

1.3 GHz universal bus-controlled TV synthesizers

Alternative Part Number

  • TDA6650T --: I2C-bus tuner PLL synthesizer in the same TV tuner function class as the TSA5526, from the successor of Philips; check pinout and supply voltage before use.
  • TDA6651T --: Similar I2C tuner synthesizer family with comparable bus control and tuning outputs; verify band and divider ranges against the original design.
  • LM7001 --: Widely used PLL frequency synthesizer for TV/radio tuners, functionally comparable to the TSA5526; requires review of reference divider and control interface differences.
  • TDA5526 --: Same I2C-bus PLL synthesizer function from the successor of Philips; pin and function compatible in most tuner designs.
  • TDA6650 --: I2C-bus tuner PLL synthesizer with comparable tuning voltage and band-switch outputs, suitable as a functional replacement.
