MST9010
GENERAL DESCRIPTION
The MST9010 is a high performance, and fully integrated graphics processing IC solution for LCD
monitors with resolutions up to XGA. It is configured with an integrated triple-ADC/PLL, a high quality
scaling engine, an on-screen display controller, and a built-in output clock generator. To further reduce
system costs, the MST9010 also integrates intelligent power management control capability for
green-mode requirements and spread-spectrum support for EMI management.
