W9951TF

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. FEATURES Triple 8-bit DAC and buffers support up to 1280 x 1024 resolution Built-in Genlock PLL regenerates pixel clock for video processor Programmable Color Key for Analog RGB inputs Genlock & Analog Keying Capability eliminates the need for VGA-Video feature connector High-speed multiplexing between digital and analog RGB signals 24-bit interface supports up to 16.7M color...
