1 / 60 page RF AMP & SERVO SIGNAL PROCESSOR S1L9225X 1 INTRODUCTION As a pre-signal & servo signal processor for the DISC-MAN, S1L9225X 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. FEATURES • RF amplifier (CD, CD-R, CD-RW applicable) • Gain setting & monitoring for the CD-R, CD-RW DISC • Focus error amp & Febias adjustment • Tracking error amp & balance, gain adjustment • FOK, defect, mirror detect • Center voltage amplifier • APC (Automatic Power Control) • APC laser controller (Controlled by Tracking Summing Signal) • 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 <Notice> LPC Control used by side beam signal, it related to pick-up assurance. When used pick-up, the specification is present extra. ORDERING INFORMATION Device Package Supply Voltage Operating Temperature S1L9225X01 Q0R0 64-LQFP-1414 2.7V 3.3V -20 °C +75°C 64-LQFP-1010 |
