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)
www.DataSheet4U.Mcoamterialization 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
