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
