The LC78622N is a digital signal processor (DSP) IC manufactured by SANYO. Below are its key specifications, descriptions, and features:

Specifications:

• Manufacturer: SANYO
• Function: Digital Signal Processor (DSP) for CD players
• Package: DIP (Dual In-line Package)
• Operating Voltage: Typically 5V
• Pin Count: 80 pins
• Applications: Used in CD player systems for digital signal processing, including EFM demodulation, error correction, and digital filtering.

Descriptions:

• The LC78622N is designed for CD player applications, providing essential digital signal processing functions.
• It includes built-in EFM (Eight-to-Fourteen Modulation) demodulation, error correction (CIRC), and digital filtering.
• The IC interfaces with other CD player components, such as servo controllers and DACs (Digital-to-Analog Converters).

Features:

• EFM Demodulation: Converts the 14-bit EFM signal from the CD into 8-bit data.
• Error Correction: Implements Cross-Interleaved Reed-Solomon Code (CIRC) for error detection and correction.
• Digital Filtering: Includes an oversampling digital filter for improved audio quality.
• Subcode Processing: Handles subcode data for track information and control.
• Low Power Consumption: Designed for efficient operation in consumer electronics.
