1) Description
The MST6151 is a high performance and fully integrated graphics processing IC solution for
multi-function LCD monitor/TV with resolutions up to SXGA/WXGA. It is configured with an
integrated triple-ADC/PLL, an ntegrated DVI/HDCP receiver, a video de-interlacer, two high
quality scaling engines, an on-screen display controller, and a built-in output clock
generator. By use of external frame buffer, PIP is provided for multimedia applications. It
supports de-interlaced full-screen video, video-on-graphic overlay, video-by-graphic split
screen, frame rate conversion, and aspect ratio conversion for various video sources. To
further reduce system costs, the MST6151 also integrates intelligent power management
control capability for green-mode requirements and spread-spectrum support for EMI
management.
