9.1
Introduction
This chassis is a digital derivative from the TCM1.0E LA
chassis and supports DVB-T reception. It uses the Mediatek
MT5335 main chip. It processes the following input/output
signals:
•
Analog and digital RF signals (PAL B/G, D/K, I, SECAM B/
G, D/K, L/L
’
, DVB-T)
•
SCART input signals (CVBS & RGB)
•
CMP input signals (YPbPr)
•
VGA input signals
•
HDMI input signals, v1.2 compliant, with HDCP, audio
included as EIA-861B standard
•
S-Video input
•
Headphone output
•
SPDIF output.
The platform is also designed for the lowest power
consumption in off/stand-by mode (<0.3W) to fulfil new Philips
CE environment policy requirement.
The MT5335 is surrounded by a tuner, a video demodulator, a
HDMI interface, SDR and flash memory, an audio amplifier,
and optionally a stand-by microprocessor (26"). For the smaller
set versions also the inverter board is serviceable.
For the block diagram, refer also to chapter 6 “Block diagrams,
Test Point Overviews, and Waveforms”.
