Notes:
•
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
) and circuit diagrams (see chapter

).Where necessary,
you will find a separate drawing for clarification.
7.1
Introduction
The TPM8.3L LA platform uses MT5301B. It supports decoder
and a TV controller offers high integration for advanced
applications. It combines a high definition video decoder, an
audio decoder, a dual-link LVDS/mini-LVDS transmitter, and
an NTST/PAL/SECAM TV decoder with a 3D comb filter
(NTSC/PAL).
