W9951TF  
TRIP 8-BIT DAC-MUXWITHGENLOCK PLL & ANALOG  
COLOR KEY  
GENERAL DESCRIPTION  
Winbond's W9951TF combines 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 YCbCr input  
formats. With the 4:2:2 YCbCr 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 via the two-wire serial interface pins.
