• Only new circuits (circuits that are not published recently)
are described.
• Figures can deviate slightly from the actual situation, due
to different set executions.
• For a good understanding of the following circuit
descriptions, please use the Wiring, Block (chapter 6) and
Circuit Diagrams (chapter 7). Where necessary, you will
find a separate drawing for clarification.
9.1 Introduction
The LC8.2A LA chassis (development name "LC08R") is a new
chassis using a Trident chipset. It covers screen sizes of 42",
47" and 52" with a new styling called "ME8".

Main key components are:
• Trident WX69 video processor
• SiL9125CTU HDMI processor
• SiL9185ACTU HDMI switch
• UV1316 tuner and TDA9886 demodulator
• Additional (optional) DFI panel including CYCLONE II
FPGA (EP2C35F48C7N) (for 100 Hz 1080p applications).
In due time this DFI panel will be replaced by an on-board
Mediatek solution.
Main features are:
• Video: Video processing is performed by the Trident video
processor SVP WX69 (item 7C01), which supports
- Digital Natural Motion for HD (HD DNM)
- MPEG Artifact Reduction
- 4-field Motion Adaptive De-Interlacing technology (MADI).
• Audio: introducing BBE
intelligibility and music performance.
• China: Support of Digital Multimedia Broadcast -
Terrestrial/Handheld (DMB-TH), the Chinese digital
television terrestrial/handheld broadcasting system
standard.
Refer to figure "LC08R Architecture" for details.
