Description and Introduction

DEFLECTION PROCESSOR FOR MULTISYNC MONITORS The TDA9105 is a deflection controller IC manufactured by PHILIPS (now NXP Semiconductors).  

### **Specifications:**  
- **Function:** Monolithic integrated circuit for deflection control in CRT monitors.  
- **Applications:** Used in computer monitors and other CRT-based display systems.  
- **Features:**  
  - Horizontal and vertical deflection control.  
  - Synchronization processing (supports multiple sync types).  
  - Adjustable geometry corrections (pincushion, trapezoid, etc.).  
  - Built-in protection circuits (e.g., X-ray protection).  
  - I²C bus interface for digital control.  

### **Descriptions:**  
- The TDA9105 integrates horizontal and vertical deflection control, reducing external component count.  
- It supports analog RGB monitors with digital control via I²C.  
- Provides dynamic focus correction for improved image quality.  

### **Features:**  
- **Horizontal Section:**  
  - Frequency range up to 150 kHz.  
  - Automatic frequency control (AFC).  
  - Adjustable phase shift.  
- **Vertical Section:**  
  - Ramp generator for vertical deflection.  
  - Adjustable amplitude and linearity.  
- **Protection Circuits:**  
  - Overvoltage protection.  
  - Beam current limiting.  
- **Power Supply:** Typically operates at 12V.  

This IC was commonly used in late 1990s and early 2000s CRT monitors. For exact electrical characteristics, refer to the official datasheet.
