RF AMP & SERVO SIGNAL PROCESSOR
PRELIMINARY
S1L9226X
INTRODUCTION
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/CD-
MP3 for the DISC-MAN. It is a hard-wired free-adjustment servo, which
automatically controlled the control point of the pre-signal portion.
