宏晶微转换芯片MS1820：YPbPr/VGA/TTL互转YPbPr/VGA/TTL芯片

General Description
    The MS1820 is a multi-functions video processor chip. It consists of 10-bit triple-ADC module, TV encoder module, 10-bit triple-DAC module and embedded OSD function. It can receive interlaced or progressive video input and graphic input. It is capable of advanced de-interlacing, video enhancement, 3D noise reduction, Y/C cross talk suppression and frame rate conversion.
