CV8988

Product description

CV8988 integrates high-performance 10bit video ADC and 24bit audio ADC as well as mature and reliable HDMI 1.3 coding and transmission module, and supports the conversion of analog VGA or analog YPbPr signals and analog/digital audio signals to standard HDMI signal output. The chip will not scale the image resolution, and the image quality is close to lossless from the visual comparison
The CV8988 package has only 88PIN, and the size is only 10x10mm. It has low power consumption and industrial design. It supports long-term operation in the environment of - 30 to 85 degrees. It has rich audio and video interfaces. It can realize the functions of VGA to HDMI, color difference to HDMI, audio ADC, video ADC, and so on. It is very suitable for various set-top boxes, players, conversion boxes, and industrial control devices to do the conversion of VGA/color difference and HDMI interfaces, video digital-to-analog conversion, and audio digital-to-analog conversion
