Description
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.
