LC895299W - 48 x Speed ATAPI (IDE) CD-ROM Decoder

Features

  • CD-DSP Block.
  • Supports full CAV operation at 48× speed.
  • Assures stable data readout by performing frame sync signal detection, protection, and interpolation.
  • Demodulates the EFM signal to produce 8-bit symbol data.
  • Applies a CRC check to the subcode Q signal and then outputs that signal via parallel I/O to the system microprocessor.
  • Performs unscrambling and deinterleaving operations to rearrange the demodulated EFM signal in the stipulated order.
