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
9. Block Diagrams ) and circuit diagrams (see chapter
10. Circuit Diagrams and PWB Layouts ). Where
necessary, a separate drawing for clarification is given.
7.1 Introduction
The TPM7.1E LA platform uses MT5395/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 four-link
LVDS transmitter, a mini-LVDS transmitter, a V-by -One
transmitter, and an NTSC/PAL/SECAM TV decoder with a 3D
comb filter (NTSC/PAL).
7.1.1 Implementation
Key components of this chassis are:
•
MT5395LUGJ System-On-Chip (SOC) TV Processor
• ENV57U09D5F Tuner (DVB T/C, analogue)
• MT5135AE DVB T/C demodulator
• TMDS351PAG HDMI Switch
• TPA6132A2RTER Earphone R/L output
• STA339BWTR Audio amplifier
• MAX17113ET Multi DC/DC
• MAX9668ETP GAMMA
• TPS65192RHDR Level shifter
