TECHNICAL SERVICE MANUAL
MST9111
GENERAL DESCRI PTION
The MST9111 is a high performance, and fully integrated graphics processing IC solution for LCD
monitors with resolutions up to SXGA. It is configured with an integrated triple-ADC/PLL, a high qualit
scaling engine, an on-screen display controller, a built-in output clock generator, and LVDS displa
interface. To further reduce system costs, the MST9111 also integrates intelligent power managemen
control capability for green-mode requirements and spread-spectrum support for EMI management.
