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,
you will find a separate drawing for clarification.
• In this chassis, the cable position numbers can be defined
via the rule that the number is always starting with an “E”
followed by the connector number of the current sourcing
board. The order is initiated from the power panel to the
SSB panel, From SSB to IR/LED panel and so on. For
instance the position number of a PSU to SSB cable would
be “ECN9302” since the connector at the PSU is numbered
“CN9302”.
7.1 Introduction
The TPM9.1L LA platform is covering the 3000 series styling. It
uses the MT5366 main microprocessor. The major difference
compared to its predecessors is ISDB support.
7.1.1 Implementation
Key components of this chassis are:
• MT5366SVOG/B
• SUT-RB211TV SONY Tuner for 3000 series (ISDB-T,
analogue)
• Sil9185ACTU HDMI Switch
• STA381BWTR 20W VQFN-48r AUDIO Amplifier
