DIGITAL SIGNAL PROCESSOR
S5L9291X
INTRODUCTION
S5L9291X is a signal processing LSI for the CD. Digital processing
functions (EFM demodulation, error correction), spindle motor servo
processing, compression for anti-rolling and anti-shock, expandable
memory control functions (4M, 16M, 64M EDO/Fast Page DRAM and
16M, 32M, 64M, 128M, 256M SDRAM ), 10-band EQ (Equalizer) Filter,
CD-Text and 1-bit DAC for the CD-MP3 Interface are installed in
S5L9291X.
