MS1852 CVBS/S-Video to VGA Video Converter
The MacroSilicon MS1852 is a CVBS/S-Video to VGA video converter. It accepts standard NTSC/PAL input, automatically detects CVBS or S-Video signals, and converts them to VGA output.
The chip integrates high-speed ADC, 3D video decoding, video processing, digital video output, and high-speed DAC. It supports picture-in-picture, high-quality OSD, frame-rate conversion, and interlaced-to-progressive conversion.
Selection Notes
MS1850 and MS1851 are not recommended for new designs. Use MS1852 for equivalent or enhanced CVBS/S-Video to VGA functionality.
