LC78622N is a digital signal processor (DSP) IC manufactured by SANYO.

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.

This IC was widely used in CD player systems during its production period. For exact electrical characteristics and detailed application circuits, refer to the original SANYO datasheet.
