Description and Introduction

Digital Signal Processor for Compact Disk Players The LC7867E is a digital signal processor (DSP) chip manufactured by SANYO. Below are the factual specifications, descriptions, and features based on available knowledge:

### **Specifications:**  
- **Manufacturer:** SANYO  
- **Type:** Digital Signal Processor (DSP)  
- **Package:** Likely a DIP (Dual In-line Package) or SOP (Small Outline Package)  
- **Power Supply Voltage:** Typically operates at 5V  
- **Functionality:** Used in CD and DVD player systems for digital signal processing  
- **Compatibility:** Designed for audio and optical disc playback applications  

### **Descriptions:**  
- The LC7867E is an integrated circuit (IC) developed by SANYO for processing digital audio signals in optical disc players.  
- It performs functions such as EFM (Eight-to-Fourteen Modulation) demodulation, error correction, and digital-to-analog conversion (DAC) interfacing.  
- Commonly found in older CD/DVD players and related audio equipment.  

### **Features:**  
- **EFM Demodulation:** Decodes the modulated signal from optical discs.  
- **Error Correction:** Includes CIRC (Cross-Interleaved Reed-Solomon Code) correction for accurate data retrieval.  
- **Digital Filtering:** Supports oversampling and noise shaping for improved audio quality.  
- **Interface Support:** Compatible with servo control and DAC components.  
- **Low Power Consumption:** Designed for efficient operation in consumer electronics.  

For exact pin configurations and detailed electrical characteristics, refer to the official SANYO datasheet (if available).
