RF SIGNAL PROCESSOR
KS1461
INTRODUCTION
The KS1461 receives optical signals from the optical pickup and makes the data-generation RF
(Radio Frequency) signals needed in the system part, and the servo error signal and monitor signals, needed for
stable servo control. The modes to which this RF IC can be applied are the CD 1×, 2×, 4×, and 8× modes
(Wide PLL +/- 20%) and the DVD 1× and 2× CLV (Constant Linear Velocity) modes.
FEATURES
