DIGITAL SIGNAL PROCESSOR FOR INTERNET AUDIO
S5L9290X02
INTRODUCTION
48-LQFP-0707
S5L9290X02 is a signal processing LSI for the Internet Audio (CD-MP3 etc)
interface only. Digital processing function (EFM demodulation, error
correction), spindle motor servo processing, wide capture range DPLL and
1-bit DAC for the Internet Audio CD player are installed in S5L9290X02.
FEATURES
• Signal processing part
— EFM data demodulation
— Frame sync detection, protection, insertion
— Sub code data processing (Q data CRC check, Q data register installed)
— Error correction (C1: 2 error correction, C2: 4 erasure correction)
— Installed 16K SRAM for De-interleave
— Interpolation
— Digital audio interface
— CLV servo control (X1, X2)
— Wide capture range digital PLL ( ± 50%)
• Digital filter, DAC part
— 4 times over sampling digital filter
— Digital de-emphasis (can be process the 32kHz, 44.1kHz, 48kHz)
— Sigma-delta stereo DAC installed
— Audio L.P.F installed
