7. MICROCONTROLLER – MSTAR(U1)
MSD9WB7GX-LF-2-T1
GENERAL DESCRIPTION
The MSD9WB7GX-2 is a highly integrated controller IC for LCD/PDP DTV applications with resolutions up to WUXGA
(1920x1200). 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 Real Video 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 MSD9WB7GX-2 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, Real Video streams, and MP3 formats from external sources such as USB interface.
For analog TV, the MSD9WB7GX-2 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 MSD9WB7GX-2 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 MSD9WB7GX-2 fulfills all requirements in advanced DTV
sets. Furthermore, MSD9WB7GX-2 can access files from networks with embedded Ethernet MAC and external PHY via the
MII/RMII interface. To reduce system costs, the MSD9WB7GX-2 also integrates intelligent power management control
capability for green-mode requirements and spread-spectrum support for EMI management.
