CV9887 basic description

CV9887 integrates high-performance 10bit video ADC and 24bit audio ADC as well as a mature and reliable HDMI1.3 encoding and sending module,

Support analog VGA or analog YPbPr signal and analog/digital audio signal to standard HDMI signal output, the chip will not scale the screen resolution,

The picture quality is close to lossless from the naked eye comparison.

The CV9887 package is only 88PIN, the size is only 10x10mm, low power consumption and industrial-grade design, supporting long-term work in an environment of -30 to 85 degrees,

Rich audio and video interfaces, which can realize VGA to HDMI, component to HDMI, audio ADC, video ADC and other functions, which are very suitable for

All kinds of set-top boxes, players, conversion boxes, industrial control equipment do VGA/color difference and HDMI interface conversion, video digital-to-analog conversion, audio digital-to-analog conversion.
