Description and Introduction

Alignment-free multistandard vision and FM sound IF-PLL demodulator The TDA9880T is a multi-standard vision and sound IF PLL demodulator for analog TV, manufactured by PHILIPS (now NXP Semiconductors). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Package:** SO20 (Small Outline 20-pin)  
- **Supply Voltage:** 5V ±10%  
- **Operating Temperature Range:** -20°C to +85°C  
- **IF Input Frequency Range:** 30 MHz to 45 MHz  
- **Demodulation Standards:** PAL, SECAM, NTSC  
- **Sound IF Frequency:** 4.5 MHz to 6.5 MHz (supports FM and AM demodulation)  
- **Low Power Consumption:** Typically 300 mW  

### **Descriptions:**  
- The TDA9880T is designed for analog TV demodulation, integrating both vision (video) and sound (audio) IF processing.  
- It features a Phase-Locked Loop (PLL) demodulator for stable and accurate signal processing.  
- The IC supports multiple TV standards (PAL, SECAM, NTSC) and sound carrier frequencies (4.5 MHz to 6.5 MHz).  
- It includes an automatic gain control (AGC) circuit for improved signal handling.  

### **Features:**  
- **Multi-standard IF demodulation** (PAL, SECAM, NTSC).  
- **Integrated PLL demodulator** for stable video and audio signal recovery.  
- **FM and AM sound demodulation** with adjustable bandwidth.  
- **Internal AGC (Automatic Gain Control)** for consistent signal levels.  
- **Low external component count** due to integrated functions.  
- **Adjustable video bandwidth** for different standards.  
- **Quasi-parallel sound processing** for improved performance.  

This information is based solely on the technical documentation for the TDA9880T from PHILIPS/NXP.

Application Scenarios & Design Considerations

Alignment-free multistandard vision and FM sound IF-PLL demodulator

Alternative Part Number

  • TDA9881T --: Same TDA988x family IF demodulator with closely matching functionality and pinout, direct drop-in for many TV tuner designs.
  • TDA9885T --: Multistandard IF demodulator from the same family, compatible signal processing and supply, suitable replacement with minor design checks.
  • TDA9886T --: Similar IF demodulator variant offering comparable performance; verify pin configuration and application notes before substitution.
