µPD64082
THREE-DIMENSIONAL Y/C SEPARATION LSI
DESCRIPTION
The µPD64082 realizes a high precision Y/C separation and a noise reduction by the three-dimension signal
processing for NTSC signal.
The three-dimension Y/C separation system can be easily realized with 4Mbit-EDO DRAM and A/D converter.
This product has a high precision 10-bit A/D converter internal, and 10-bit signal processing (only for luminance
signal) for high picture quality.
This LSI includes the Wide Clear Vision ID signal decoder and Horizontal Helper signal decoder.
FEATURES
• Includes a high performance pipeline 10-bit A/D converter for composite and luminance signal, and 8-bit A/D
converter for chroma signal processing.
• High resolution picture with 4 times of ratio in the previous system.
• Easy to make the three-dimension Y/C separation and YNR/CNR system with 4MBit-EDO DRAM.
• Includes system clock generator, 2-ch of A/D converter, and 2-ch of D/A converter.
• Includes HH decoder (Required the field memory).
• I2C bus control.
• Single power supply of 3.3 V.
