5.1. Description
MSD9WB9PT-2 (Main IC) (U5)
The MSD9WB9PT-2 is MStar’s most up-to-date system-on-chip solution for flat panel 
integrated digital television products. Building on the success of MStar’s preceding SOC 
series, the MSD9WB9PT-2 provides most cost-effective solution for DTV application with 
creative and attractive features exclusively presented by MStar.
The MSD9WB9PT-2 integrates DTV/multi-media all-purpose AV decoder, DVB-T 
demodulator, VIF demodulator, and Sound/Video processor into a single device. This 
allows the overall BOM to be reduced significantly making the MSD9WB9PT-2 a very 
competitive multi-media DTV solution. For ATV users, the MSD9WB9PT-2 provides multi-
standard analog TV support with adaptive 3D video decoding and VBI data extraction. 
The build-in audio decoder is capable of decoding FM, AM, NICAM, A2, BTSC and EIA-J 
sound standards. The MSD9WB9PT-2 supplies all the necessary A/V inputs and outputs 
to complete a receiver design including a multi-port HDMI receiver and component video 
ADC. All input selection multiplexed for video and audio are integrated, including full 
SCART support with CVBS output. The equipped MStar MACE-5 color engine is the 
latest masterpiece from
MStar famous color engine series providing excellent video and picture quality in Full-HD 
and large-scale displaying system. 
To meet the increasingly popular energy legislative requirements without the use of 
additional hardware, the MSD9WB9PT-2 has an ultra low power standby mode during 
which an embedded MCU can act upon standby events and wake up the system as 
required.
The MSD9WB9PT-2  is composed of several modules:
