Description and Introduction

Digital Audio Decoder/Processor for A2 and NICAM Television/Video Recorders The STV8257DSX is a high-voltage deflection processor IC manufactured by STMicroelectronics.  

### **Specifications:**  
- **Supply Voltage:** 9V to 16V  
- **Horizontal Drive Output:** Capable of driving an external transistor  
- **Vertical Drive Output:** Linear sawtooth output for vertical deflection  
- **Protection Features:** Thermal shutdown, overvoltage protection  
- **Package:** DIP-16 (Dual In-line Package)  

### **Descriptions:**  
The STV8257DSX is designed for CRT (Cathode Ray Tube) deflection systems in televisions and monitors. It integrates horizontal and vertical deflection control functions, reducing external component count.  

### **Features:**  
- **Horizontal Section:**  
  - Built-in oscillator with PLL (Phase-Locked Loop) synchronization  
  - Soft start and shutdown  
  - X-ray protection  
- **Vertical Section:**  
  - Adjustable vertical amplitude and linearity  
  - DC-coupled vertical output  
  - Vertical blanking pulse generation  
- **Low Power Consumption:** Optimized for energy efficiency  

This IC is primarily used in analog CRT display systems for deflection control.
