Full CAV 20× CD-ROM Decoder with Built-in ATA-PI (IDE) Interface and CD-DSP
Preliminary Overview
The LC895297 is a single-chip CD-ROM decoder and CD-DSP system that supports full CAV 20× operation and includes a built-in ATA-PI (IDE) interface. I/O channel.
- Performs unscrambling and de-interleaving to reorder the demodulated EFM signal in the prescribed manner.
- Performs error code detection and correction, and flag processing. (C1: dual errors, C2: four errors)
- Sets the C2 flags based on the C1 flags and a C2 check, and performs interpolation or muting depending on the C2 flags. Adopts a 2-point interpolation circuit, and converges the...
