KS1452

DVD SERVO PROCESSOR KS1452 INTRODUCTION The KS1452 is a 1-chip IC of the Digital Servo Signal Processor/Wide capture range PLL for DVDPs. FEATURES Digital Servo IC for CD/CDROM (x1, x2, x4, x8), and DVD (x1) Complete Automatic Adjustment Function (Focus/Tracking Loops input gain, offset, balance, loop gain) of a Digital Filter for each Servo Loop, reducing the number of external parts Built-in AGC function to respond ideally to different disc types High Speed migration control (built-in Sled FG Encoder) and built-in Search Algorithm for speed control Built-in 8-bit A/D Converter and 9-bit D/A Converter Able to select various filter characteristics and internal constants from Syscon Interface with Syscon is 1-bit serial and 8-bit parallel compatible Built-in circuits for compensation in cases of Drop Out and Shock Built-in 16-bit Track Counter Able to select the best method from multiple Search Algorithms Widening the range by high speed sampling (151.2Khz), thus improving the Servo function Built-in Wide Capture Range (+/– 50%) PLL Built-in EFM slice Built-in DAC type F/V for RF EQ adjustment FD/PD gain adjustment possible Built-in Wide range VCO (20–280Mhz) 5V single power supply 80 QFP Materialization www.DataSheet4U.com 1 KS1452 DVD SERVO PROCESSOR BLOCK DIAGRAM SSTOP/PS0 SMON RSTB TILTO XOUT DFCT LOCK TZCA MIRR FOKB TEST DIRC PS1 TILTI PHI1 XO XI www.DataSheet4U.com VREF ENV TZCO SME TE FE TIMING A/D CONVERTER...
