DVD PLAYER DIGITAL SERVO & DSP IC
S5L1454A
INTRODUCTION
KS1454 is a DVDP (Digital Video Disc Player) 1-chip LSI which includes the digital servo and DSP(Digital Signal
Processor) features.
Servo Block performs the digital servo function, which controls disc speed and pick-up location as it retrieves
signals from the disc (CD,VCD,DVD). Servo block contains the wide capture PLL.
DSP block receives the EFM signal as an input and performs buffer control for demodulated data output while
EFM demodulation and error corrections are being carried out.
FEATURES
