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.
