Descriptions:

The LC78622 is a DSP chip primarily used in CD (Compact Disc) players and related audio systems. It performs digital signal processing tasks such as error correction, interpolation, and digital filtering to ensure high-quality audio playback.

Features:

  • Error Correction: Includes CIRC (Cross-Interleaved Reed-Solomon Code) for CD data error correction.
  • Digital Filter: Built-in 8x oversampling digital filter for improved audio quality.
  • EFM Demodulation: Supports Eight-to-Fourteen Modulation (EFM) decoding.
  • Subcode Processing: Handles subcode data extraction (for track/time information).
  • Low Jitter: Designed to minimize timing jitter for stable audio output.
  • Compatibility: Works with standard CD-DA (Compact Disc Digital Audio) formats.

This IC was commonly used in mid-to-high-end CD players during its production period. For exact pin configurations and application circuits, refer to the official SANYO datasheet.
