Chrontel CH8438
The CH8438’s high-speed analog multiplexer allows simultaneous display of video (digital RGB) with graphics (analog RGB), making CH8438 ideal for video games, editing, PC video, and for applications requiring picture-in-picture capability. With the 4:2:2 YCrCb input format, a built-in color space converter translates YUV video information to RGB before muxing with the analog graphics input, while the 4:4:4 YUV format accepts 2’s complement Red and Blue data, and provides analog YUV outputs. The programmable functions include digital input formats; video attributes of contrast, hue, and brightness; analog input attenuation; and switching delay.
