DVD PLAYER DIGITAL SERVO & DSP IC
S5L1454A
1
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
MICOM
8bit parallel interface
Built-in direct memory access (DVD/CD)
PLL
Built-in wide capture range (
50%) PLL
Built-in EFM slice
Built-in F/V converter for RF EQ adjustment of DAC method
Charge-pump PWM control method
FD/PD gain adjustment
Built-in wide range VCO(20 - 100MHz)
SERVO
CD/CD-ROM 1,2x, DVD 1x compatible digital servo IC.
complete automatic adjusting FEATURE.
(Focus/Tracking Loop's Input Gain, Offset, Balance, Loop Gain)
Each servo loop has a digital filter, reducing the number of external parts.
Built-in AGC FEATURE that responds optimally to various disc types.
High speed moving control(built-in SLED FG Encoder).
Built-in speed controlling search algorithm.
Built-in 10bit A/D Converter and 10bit D/A Converter.
Various filter characteristics and internal constants can be set from MICOM.
Built-in defect and shock response.
Built-in 16bit track counter.
Chooses the best method from multiple search algorithm.
Servo operation improved by widening the range through high speed sampling of 151.2kHz
