Description and Introduction

Baseband delay line The TDA4663 is an integrated circuit (IC) manufactured by **NXP Semiconductors** (formerly Philips Semiconductors).  

### **Specifications:**  
- **Function:** Digital delay line for PAL and NTSC color difference signals.  
- **Package:** Typically available in a **16-pin DIP (Dual In-line Package)** or **SO16 (Small Outline)**.  
- **Supply Voltage:** **5V ±10%**.  
- **Power Consumption:** Low power consumption (exact value depends on operating conditions).  
- **Delay Time:** **64 µs (microseconds)** for PAL signals and **~53.6 µs** for NTSC signals.  
- **Operating Temperature Range:** **-25°C to +70°C**.  

### **Descriptions:**  
The TDA4663 is designed for use in **TV and video processing applications**, particularly for delaying color difference signals (B-Y and R-Y) in PAL and NTSC systems. It integrates a **1H (horizontal line) delay** function, essential for color signal processing in analog TV receivers.  

### **Features:**  
- **Digital delay line** with internal **6-bit analog-to-digital (A/D) and digital-to-analog (D/A) converters**.  
- **Comb filter functionality** for improved color signal separation.  
- **No external components required** for delay adjustment.  
- **Low noise and high signal integrity** due to digital processing.  
- **Compatible with both PAL and NTSC** color systems.  

For exact datasheet details, refer to **NXP's official documentation**.

Application Scenarios & Design Considerations

Baseband delay line

Alternative Part Number

  • TDA4665 --: Same TDA466x family baseband delay line IC with closely matching function and pinout, commonly used as a direct substitute in PAL/NTSC video processing circuits.
  • TDA4661 --: Sister device in the same TDA466x delay-line series offering equivalent 1H delay-line functionality; verify supply voltage and pin configuration before substitution.
  • TDA4670 --: Related Philips/NXP video delay-line IC with similar signal-processing role; acceptable fallback when TDA466x parts are unavailable, subject to datasheet comparison.
