MS1835

————————————————————————————————————


The MS1835 is a single chip RGB to CVBS/S-Video converter with embedded MCU and memory. It consists of 10-bit triple-ADC for RGB input, NTSC/PAL encoder with 10-bit DAC for output, integrated OSD function. It is capable of video enhancement, 3D noise reduction, brightness/saturation/sharpness and hue adjustment, which can help the designer acquire the required video quality. No programming technology can help customers to reduce production cost and cycle.
