9. Circuit Descriptions, Abbreviation List, and IC Data Sheets
Index of this chapter:
9.1 Introduction
9.2 Main Supply
9.3 Abbreviation List
9.4 IC Data Sheets
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 (chapter 6) and
circuit diagrams (chapter 7). Where necessary, you will find
a separate drawing for clarification.
9.1
Introduction
This chassis (member of the "TV522" platform) is a derivative
from the PB52.1HU LA chassis. It comes with the MG8 styling.

Figure 9-1 Architecture of PB522 platform
For a description of most circuitry, refer to the PB52.1HU LA
Service Manual.
Some more delta's w.r.t. the previous PB52.1HU LA chassis
are:
•
No support of MPEG4-encoded transport streams:
removal of the PCMCIA controller (STI7101) with Common
Interface slot.
•
The addition of a separate DC-DC converters panel ("DC").

PB522 Architecture Overview
For details about the chassis block diagrams refer to chapter
"Block diagrams, Test Point Overview, and Waveforms". An
overview of the PB522 architecture can be found in figure 9-1,
"Architecture of PB522 platform".
