Description and Introduction

Built-in Subcode Interface CD-ROM/CD-I Error Correction LSI The LC89517 is a digital signal processor (DSP) chip manufactured by SANYO. Below are the factual specifications, descriptions, and features of the LC89517:  

### **Specifications:**  
- **Manufacturer:** SANYO  
- **Function:** Digital Signal Processor (DSP) for CD and CD-ROM applications  
- **Package Type:** SOP (Small Outline Package)  
- **Pin Count:** 64 pins  
- **Operating Voltage:** Typically operates at 5V  
- **Clock Frequency:** Supports system clock inputs for CD signal processing  
- **Error Correction:** Includes built-in error correction (CIRC: Cross-Interleaved Reed-Solomon Code)  
- **EFM Demodulation:** Handles Eight-to-Fourteen Modulation (EFM) decoding  
- **Subcode Processing:** Capable of subcode extraction and processing  

### **Descriptions:**  
The LC89517 is a DSP IC designed for CD and CD-ROM systems. It performs critical functions such as EFM demodulation, error correction, and subcode processing. It is commonly used in CD players and CD-ROM drives to ensure accurate data retrieval from optical discs.  

### **Features:**  
- **EFM Demodulation:** Converts EFM signals to digital data.  
- **CIRC Error Correction:** Implements error detection and correction for reliable data recovery.  
- **Subcode Extraction:** Processes subcode information (e.g., track time, disc info).  
- **Digital PLL:** Includes a phase-locked loop for stable clock synchronization.  
- **Servo Control Interface:** Supports servo control signals for disc tracking and focus.  
- **Serial Data Output:** Provides processed data in serial format for further processing.  

This information is based solely on the known specifications and features of the LC89517 DSP chip by SANYO.
