Description and Introduction

Single standard VIF-PLL with QSS-IF and FM-PLL demodulator The TDA9808T is a monolithic integrated circuit manufactured by Philips (now NXP Semiconductors). Below are the factual specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Manufacturer:**  
- **PH (Philips Semiconductors, now part of NXP Semiconductors)**  

### **Specifications:**  
- **Function:** FM/AM IF amplifier and demodulator for TV and radio applications.  
- **Package:** SO20 (20-pin Small Outline package).  
- **Supply Voltage Range:** 4.5V to 8V.  
- **Operating Temperature Range:** -20°C to +70°C.  
- **IF Frequency Range:**  
  - FM: 4.5 MHz to 6.5 MHz.  
  - AM: 38.9 MHz (typical for TV applications).  
- **Low Power Consumption:** Typically 50 mA.  
- **High Sensitivity:** Suitable for weak signal reception.  
- **Integrated AGC (Automatic Gain Control):** Ensures stable signal output.  
- **Signal-to-Noise Ratio (SNR):** Optimized for clear audio demodulation.  

### **Descriptions:**  
- The TDA9808T is designed for intermediate frequency (IF) signal processing in TV and radio receivers.  
- It includes FM and AM demodulation capabilities, making it suitable for analog TV sound processing.  
- The IC integrates amplification, demodulation, and AGC functions in a single chip.  

### **Features:**  
- **FM and AM IF Amplification:** Supports multiple IF frequencies.  
- **Built-in Demodulators:** For FM and AM signals.  
- **Low External Component Count:** Reduces PCB space and cost.  
- **Wide Supply Voltage Range:** Compatible with various power supplies.  
- **Thermal Protection:** Enhances reliability.  
- **Mute Function:** For noise suppression during weak signal conditions.  

This information is based on the original Philips/NXP datasheet for the TDA9808T.

Application Scenarios & Design Considerations

Single standard VIF-PLL with QSS-IF and FM-PLL demodulator

Alternative Part Number

  • TDA9801 --: Same TDA980x family of TV IF demodulators with similar functionality; NXP is the successor of Philips, so pinout and performance are closely matched.
  • TDA9800 --: Earlier member of the same Philips/NXP TV IF demodulator family, electrically very similar and often used as a drop-in substitute in TV tuner designs.
  • LA7566 --: Alternative TV IF demodulator IC from a different manufacturer and series, offering comparable video and sound IF demodulation functions for TV applications.
  • TDA9808 --: Same TV IF demodulator function from the successor of Philips; the non-T package variant is functionally equivalent and widely available.
  • TDA9809T --: Same TDA980x family IF demodulator from the original manufacturer's successor NXP, with very similar functionality and pinout, making it a close drop-in substitute.
  • TDA9809 --: Closely related NXP TV/VCR IF signal processing IC with comparable demodulator function; often used as a replacement in similar applications after checking pin compatibility.
  • TDA9815 --: NXP multi-standard IF demodulator offering similar functionality; a viable alternative for TV IF processing designs with minor circuit adjustments.
