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 (development name "Jaguar ") is: The move from
the analogue world to the digital world. W.o.w. from signal
processing via "hardware circuits" to signal processing via
"software algorithms". This means: no software = no picture
and sound!
Some key components are:
• Common Interface (CI) circuitry (only for digital sets).
• MPIF (PNX3000).

• AVIP/COLUMBUS (PNX2015).
• SPIDER (T6TE0TBG).
• VIPER 2 (PNX8550).
• FPGA (EPLD or MOP).
• PACIFIC 3 (T6TF4HFG-0002).
9.1.1 Features
The main features for this chassis are:
• Fit for both analogue and digital signal processing, this by
converting analogue signals into digital transport streams
and allowing seamless zapping between all possible signal
sources. This makes the chassis applicable for e.g.
receiving DVB-T in an integrated product form.
• AmbiLight: a unique technology that, in real-time, analyses
incoming television signals and produces background
lighting that matches the images displayed on the screen.
• The internal digital processing allows new "Multi-Media"
applications such as Content Browser, Memory Card Slot,
Local Area Network support and all kinds of streaming
applications.
• The chassis can be upgraded in the future with internal
functionality such as Personal Video Recording, DVD/RW,
MPEG playback.
The Pacific 3 provides Pixel Plus in all models. This ensures
additional sharpening, and contrast and colour enhancements
to the picture.
9.1.2 Jaguar Architecture Overview
For details about the chassis block diagrams refer to chapter
"Block diagrams, Test Point Overview, and Waveforms". An
overview of the Jaguar architecture can be found in figure
