GENERAL DESCRIPTION
The MSD209FG 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 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 MSD209FG comprises an MPEG-2 transport processor with advanced section
filtering capability, an MPEG-2 (MP@HL profile) video decoder, an 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 MPEG-4, JPEG, MP3 formats from external
sources such as USB interfaces.
For analog TV, the MSD209FG includes NTSC/PAL/SECAM multi-standard video decoder comprising a 3-D
motion adaptive comb filter and time-based correction, and a NICAM/A2 audio decoder to support worldwide
television standards. The MSD209FG 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.
By integrating peripherals including two USB 2.0 host controllers, UARTs, IR, SPI, I2C, and PWM, the
MSD209FG fulfills all requirements in advanced DTV sets. To further reduce system costs, the MSD209FG
also integrates intelligent power management control capability for green-mode requirements and
spread-spectrum support for EMI management.
The register information provided in the Register Description section is related to analog function of the
MSD209FG. For details on the digital function, please refer to the Application Programming Interface (API)
Guide.
