7-2 RF
7-2-1 RIC1 (KS1463)
KS1463 is combined with KS1455 as bipolar IC developed for DVD SERVO system.
Main features include DVD waveform equalizing, CD waveform equalizing, focus error signal generation, 3-beam
tracking error signal generation, DPD 1-beam tracking error, defect, envelope, MIRR output, Laser Power Control,
etc.
7-2-1 (a) Basic Potentiometer
S5L1463 Uses 5V/3.3V and reference voltage is 2.5V.
V (Pin 19, 32, 45, 49, 58-) terminal is needed for IC, which uses the peripheral V.
7-2-1(b) RF signal
Fig. 7-11 shows the flow of signal generated by the pick-up.
A, B, C, D signals detected from pick-up are converted in to RF signal(A+B+C+D) via RF summing AMP.
Fig. 7-12 shows the waveform-equalizing block diagram for the RF signal.
It outputs to EQout (Pin 70) terminal by initially changing switching AMP gain of DVD and CD, and then adjust-
ing the level in RF SUM & AGC.
RF SUM and AGC is Contvolled by PWM Signal and pin 78~80.
EQout Pin is Connected EQin.
