S5L9250B Description
DATA SHEET S5L9250B INTRODUCTION The CD-ROM 48X 1 chip receives the input signal read from the CD-DA/VIDEO-CD/CD-ROM disc after handling by the RF amplifier. The signal is input into the digital servo block which has a built-in DSP core, and goes through focus and tracking adjustments. The RF signal input into a data path goes through the data slicer, PLL, EFM demodulator, C1/C2 ECC and the audio handling block.
