Introduction
This chassis supports PC analogue input up to WXGA
resolution, and supports TV (RF) for Europe systems: PAL B/
G, PAL D/K, PAL I, SECAM B/G, SECAM D/K, CVBS, HDMI
and VGA signal input.
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.

It uses one main ICs: MT8200ATE (One Chip LCD-TV
Controller).
The MT8200ATE is a highly integrated single chip for LCD TV
supporting video input and output format up to HDTV. It
includes 3D comb filter TV decoder to retrieve the best image
from popular composite signals. Embedded HDTV/VGA
decoders let the high bandwidth input signals perfectly
reproduced.
The 16/8 bits digital port may accept CCIR-656/601 external
digital input video source. New 2
nd
generation advanced
motion adaptive de-interlacer converts accordingly the
interlace video into progressive one with overlay of a 2D
Graphic processor. It incorporates advanced full function
colour processing with fully 10-bit path provides high quality
video contents.
Its on-chip audio processor decodes analog signals from tuner
with lip sync control, delivering high quality post-processed
sound effect to customers.
The on-chip microprocessor reduces the system BOM and
shortens the schedule of UI design by high level C program.
The MT8200 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.
The CM2021 HDMI Receiver Port Protection and Interface
Device is specifically designed for next generation HDMI Host
interface protection. An integrated package provides all ESD,
level shift and backdrive protection for an HDMI port in a single
38-Pin TSSOP package.
