1.1. U4201 (MST9A885GL)
GENERAL DESCRIPTION
The MST9A885GL
is a high performance and fully intergrated IC for multi-function LCD monitor/TV with resolution up to SXGA
(1280x1024)/WXGA+(1400x990). It is configured with an integrated triple-ADC/PLL,an integrated DVI/HDCP/HDMI receiver.a multi-standard TV video and
audio decoder,a video de-interlacer,a scalling engine,the MStarACE-3 color engine,an on –screen display controller,an 8-bit MCU and a built –in output
panel interface.By use of external frame buffer,3-D video decoding and processing are fulfilled for high-quality TV applications.To futher reduce system
costs,the MST9A885GL als integrates intelligent power management control capability for green-mode requirements and spread-mode requirements and
spread-spectrum support for EMI management.
