1、 MSD 209FG
GENERAL DESCRIPTION
The MSD209GL is a highly integrated controller IC for LCD/PDP DTV applications with resolutions
up to full-HD(1920 x 1080). It is configured with an integrated triple-ADC/PLL, a multi-standard TV
video and audio decoder, a motion adaptive video de-interlacer, a scaling engine, the MStarACE-3
color engine, an advanced 2D graphics engine, a transport processor, a high-definition (HD) MPEG
video decoder, a high-definition (HD) H.264 video decoder, a RealVideo decoder, a JPEG video
decoder, a MPEG-4 decoder, and a 24-bit DSP for MPEG audio decoding, a DVI/HDCP/HDMI
receiver, and a peripheral control unit providing a variety of HDTV control functions.
For digital TV application, the MSD209GL comprises an MPEG-2 transport processor with advanced
section filtering capability, an MPEG-2 (MP@HL profile) video decoder, a MPEG-4 decoder, a H.264
video decoder, and an audio DSP decoder for MPEG audio streams, MPEG layer I and II digital
audio decoder with analog audio outputs that are designed to support existing and future DVB-T
programs while handling conditional access. Furthermore,it is also possible to decode JPEG,
RealVideo streams, and MP3 formats from external sources such as USB interface.
For analog TV, the MSD209GL includes NTSC/PAL/SECAM multi-standard video decoder
comprising a 3D motion adaptive comb filter and time-based correction, and a NICAM/A2 audio
decoder to support worldwide television standards. The MSD209GL is also configured with a VBI
processor to decode digital information such as Close Caption/V-chip/teletext/WSS/CGMS-A/VPS.
In addition, the MStar advanced LCD TV processor enhances video quality, motion adaptive
de-interlacer, picture quality adjustment units, and MStarACE-3 color engine.
With USB 2.0 host controllers, UART, IR, SPI, I2C, and PWM, the MSD209GL fulfills all
requirements in advanced DTV sets. To reduce system costs, the MSD209GL also integrates
intelligent power management control capability for green-mode requirements and spread-spectrum
support for EMI management.
