LC895297 Overview
EN 5785 CMOS LSI LC895297 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. Performs unscrambling and de-interleaving to reorder the demodulated EFM signal in the prescribed manner. Performs error code detection and...
LC895297 Key Features
- Full CAV 20× operation ATA-PI (IDE) interface Supports the use of EDO DRAM. Supports the use of up to 4 Mbits of buffer
- Package Dimensions
- The IC inputs a high-frequency signal, slices that signal at the correct level, converts that result to an EFM coded sig
- Uses an external 16.9344-MHz crystal element to generate a standard clock and to correctly generate the required interna
- Performs frame synchronization, signal detection, protection, and insertion, and assures stable data readout
- Demodulates the EFM coded signal to produce 8-bit symbol data
- After applying a CRC check to the subcode Q signal, outputs that signal to a microprocessor over a parallel
