MS1820

————————————————————————————————————


The MS1820 is a multi-functions video processor chip. It consists of triple 10bit ADC module, TV encoder module and a triple DAC module with OSD function. It can accept interlaced or progressive video input and graphic input. In both analog and digital channels, it provides a high quality display output. It is capable of advanced de-interlacing, video enhancement, 3D noise reduction, Y/C cross talk suppression and frame rate conversion.OEMs can easily design a low cost and high quality system solution by MS1820’s high integration and Software support.
