S1L9226X Datasheet | Samsung Semiconductor

PRELIMINARY RF AMP & SERVO SIGNAL PROCESSOR INTRODUCTION 48-LQFP-0707 As a pre-signal & servo signal processor for the DISC-MAN, S1L9226X is a low voltage, low consumption current IC that can read CD-RW, and CD-R discs and can be applied to various products, such as the CDP/VCD/CDMP3 for the DISC-MAN. It is a hard-wired free-adjustment servo, which automatically controlled the control point of the pre-signal portion.
