W9951TF
DESCRIPTION
Winbond's W9951TF bines three 8-bit DACs, a YUV-to-RGB Color Space Converter, high-speed analog multiplexers, analog input attenuators, video buffers, a genlock PLL, analog color key detector, and numerous programmable features in one integrated circuit. The W9951TF's high-speed analog multiplexer allows simultaneous display of video (digital RGB or YUV) with graphics (analog RGB), making the W9951TF ideal for video games, video editing, CD and PC video, and for applications requiring picture-in-picture capability. The W9951TF provides a 24-bit digital interface, which supports both RGB and 4:2:2 YCb Cr input formats. With the 4:2:2 YCb Cr input format, a built-in color space converter translates YUV video information to RGB before mixing with the analog graphics input. There are eighteen control registers, which provide access to video attribute control functions of contrast, hue, brightness, PLL divider value, and analog color key range. These functions are programmable...
