Overview

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.
In the case of a CD-DA, the signal is output through the 1-bit DAC.
In the case of a CD-ROM, the signal is input into an external CD-ROM controller for handling, then transmitted to the host through the ATAPI I/F.
Also, if you operate the CD-DA in audio buffering mode while already in CAV mode, the signal is stored in the CD-ROM controller DRAM at high speed, then output at 1x from the CD-ROM controller, after passing through the 1-bit DAC built-in to the S5L9250B.
