7.1 Introduction
The TPM8.2E LA platform uses MT5366/MT5135. It supports
decoder and a TV controller offers high integration for
advanced applications. It combines a transport de-multiplexer,
a high definition video decode, an AC3 decode, a dual-link
LVDS/mini-LVDS transmitter, and an NTSC/PAL/SECAM TV
decoder with a 3D comb filter (NTSC/PAL).

Figure 7-1 Architecture of TPM8.2E LA
• 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 (see chapter
9. Block Diagrams) and circuit diagrams (see chapter
10. Circuit Diagrams and PWB
you will find a separate drawing for clarification.
