CD-ROM 48X RF AMP
S1L9251X
INTRODUCTION
CD-ROM 48X RF AMP Chip is RF pre signal processor and processes signals from optical pick-up. This chip
processes main signal through summing amp, AGC block, EQ block, and generates SERVO error signals for
SERVO control. It can playback CD-ROM and CD-RW disc.
