S1L9226X01-Q0R0

PRELIMINARY RF AMP & SERVO SIGNAL PROCESSOR S1L9226X 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. FEATURES RF amplifier (CD, CD-R, CD-RW applicable) Gain setting & monitoring for the CD-R, CD-RW DISC RFAMP offset adjustment Focus error amp & Febias adjustment Tracking error amp & balance, gain adjustment FOK, defect, mirror detect Center voltage amplifier APC (Automatic Power Control) RF AGC & EQ control (AGC Level Control Compatible) Enhanced EFM slice (Double Asymmetry Method) Focus servo loop & offset adjustment Tracking servo loop & offset adjustment Sled servo loop Spindle servo loop Auto-sequence Fast search mode (1 - 36000 track jump) Interruption countermeasure Focus & Tracking servo muting controlled by EFM duty check RF peaking prevention system by EFM duty check Focus, tracking, spindle loop pole move option Operating voltage 2.7V  3.3V Power saving mode LPC Control used by side beam signal, it related to pick-up assurance.
