Basic description of CV9886

CV9886 integrates high-performance 10bit video ADC and 24bit audio ADC, as well as a mature and reliable HDMI1.3 encoding and sending module. It supports analog VGA or analog YPbPr signal and analog/digital audio signal to standard HDMI signal output. The chip will not distinguish the picture.

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

CV9886 only has 56PIN, size is only 7x7mm, low power consumption and industrial-grade design, supports long-term work under -30 to 85 degrees, and can realize VGA to HDMI, component to HDMI and other functions on a single chip. It is very suitable for all kinds of set-top boxes, players,

Conversion box, industrial control equipment to do the conversion of VGA and HDMI interface.

CV9886 embeds a 32-bit ARM Cortex™-M0 processor with a speed of up to 48Mhz, realizing a single-chip system without the need for an external control module.
