MS1830

————————————————————————————————————


The MS1830 is a Single Chip RGB to CVBS/S-video Converter with embedded SDRAM. It consists of triple 10bit A/D converters for RGB input, NTSC / PAL encoder with 10-bits D/A for output, which have video enhancement, 3D noise reduction , the brightness, saturation, sharpness and hue are also adjustable to help the designer acquire required video quality, also integrating OSD function.

OEMs can easily design a low cost and high quality system solution by MS1830’s high integration and Software support.
