Description

S5L1454A is a DVDP (Digital Video Disc Player) 1-chip LSI which includes the digital servo and DSP(Digital Signal Processor) features.

S5L1454A 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.

S5L1454A 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
