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.
