MSD9WB7GX-LF-2
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. 
The MSD9WB7GX-LF-2 is composed of several modules:
