4. Power Supply Requirements

The external AC power operating range shall be from 90 to 264Vac

5. LCD Module Handling Precautions

5.1. Handling Precautions

(1) Since front polarizer is easily damaged, pay attention not to scratch it.
(2) Be sure to turn off power supply when inserting or disconnecting from input connector.
(3) Wipe off water drop immediately. Long contact with water may cause discoloration or

spots.
(4) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
(5) Since the panel is made of glass, it may break or crack if dropped or bumped on hard

surface.
(6) Since CMOS LSI is used in this module, take care of static electricity and insure human

earth when handling.
(7) Do not open nor modify the Module Assembly.
(8) Do not press the reflector sheet at the back of the module to any directions.
(9) In case if a Module has to be put back into the packing container slot after once it was

taken out from the container, do not press the center of the CCFL Reflector edge.

Instead, press at the far ends of the CFL Reflector edge softly. Otherwise the TFT

Module may be damaged.
(10) At the insertion or removal of the Signal Interface Connector, be sure not to rotate nor

tilt the Interface Connector of the TFT Module.
(11) After installation of the TFT Module into an enclosure (LCD monitor housing, for

example), do not twist nor bend the TFT Module even momentary. At designing the

enclosure, it should be taken into consideration that no bending/twisting forces are

applied to the TFT Module from outside. Otherwise the TFT Module may be damaged.
(12) Cold cathode fluorescent lamp in LCD contains a small amount of mercury. Please

follow local ordinances or regulations for disposal.
(13) Small amount of materials having no flammability grade is used in the LCD module.

The LCD module should be supplied by power complied with requirements of Limited

Power Source (IEC60950 or UL1950), or be applied exemption.

4. Circuit Description

A. Analog Switch and Video input.

MT8202 is a highly integrated video and audio single chip processor for emerging
HDTV-Ready LCD TV. It includes one 3D/2D TV Decoder recovering the best image from
CVBS, and in addition, its analog input also support popular S-Video, Component, VGA video
source. On-chip advanced motion adaptive de-interlacer (MDDitm) converts accordingly the
interlace video into smooth non-flicking progressive motion pictures.

Analog switch is built in MT8202 and accept CVBS, YPbPr, S-Video, RGB signal directly to
internal video front end. For most system application, there is no need to add external
components to add analog video multiplexer on board.

The video ADC sample analog input signals. After ADC, all signal processing is digital
domain.The source select multiplex all inputs from digital and analog video ports and route
them into Main and PIP data path.

B. 3D comb filter, Video Decoder, Deinterlacer and Scaling controller.

MT8202 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. 24/16/8 bits digital port may accept all kinds of external digital input
video source. New 2nd generation advanced motion adaptive de-interlacer converts
accordingly the interlace video into progressive one with overlay of a 2D Graphic processor.
Advanced full function color processing with fully 10-bit path provides high quality video
contents. Independent two Flexible scalers provide wide adoption to various LCD panels for
two of different video sources at the same time. MT8202 supports alpha blending for Video
and two OSD planes. It also supports 10bit gamma correction and advanced dithering
processing for LCD display with 6/8/10 bit output.

C. DTV and HDMI.

MT5111CE is a fully integrated single-chip 8-VSB and 64/256-QAM demodulator. The chip
is designed specifically for the digital terrestrial HDTV and CATV receivers
includes a 10-bit A/D converter, 8-VSB/QAM demodulator, TCM (Trellis-Coded modulation)
decoder, and Reed- Solomon Forward Error Correction decoder. Moreover, an internal
controller handles the acquisition and tracking to ensure the best receiving performance.

The internal controller communicates with the external host controller via the I2C-compatible
interface, and also provides direct control to the RF tuner via the second I2C-compatible
interface.

MT5111CE accepts either the direct IF signals and the IF signals are sampled by a 10-bit A/D

converter. Afterward, the digitized samples are further processed for adjacent channel

interference rejection. MT5111CE measures the power level of the digitized sequence, and
feeds the control voltages back to the RF tuner and the IF amplifier respectively. The control
voltages are converted to analog signals through the on-chip 1-bit sigma-delta D/A converters
plus the off-chip R-C low-pass filters. The automatic gain control keeps the received power
level at a desired level and maximizes the received SNR.

The MT5351AG is a DTV Backend Decoder SOC which support flexible transport demux,

HD MPEG-2 video decoder, JPEG decoder, MPEG1,2, MP3, AC3 audio decoder, HD TV
encoder. It incorporates a processor for system control. The processor issues instructions to
control the peripheral via I²C and communicates with MT8202 via UART. DDR
externally connected to the MT5351AG, the unified memory allows all internal decoders can
share data,which reduces external memory types and capacities.

The MT5351AG receives bitstream input in TS format, and then separates the TS into audio

and video PES, analyzing the PES header, and transferring the PES to the audio and video
decoders.

D. Audio

MT8202 incorporates a on-chip audio processor decodes whole world standard audio signals
from tuner with lip sync control, delivering high quality post-processed sound effect to

customers. Audio interface accept analog audio signal from Tuner, e.g. SIF or AF. It also
includes preprocessing circuit to filter the noisy audio signals. Audio decoder will decode the
BTSC, and output best sound with enhanced 3D surround post-processing.

The AD12250 converts stereo single-ended analog input signals into 24-bit I2S digital audio
data through on-chip anti-aliasing filter, multi-bit Σ-Δ modulator, decimation filter and
high-pass filter which removes dc offsets. External analog audio signal , such as AV, S-video,
etc. is directly fed into AD12250 via a audio switch and converted to I2S digital audio data.
Digital audio, such as HDMI and DTV, have decoded by MT5351 and MT8293, is converted
to I2S digital audio already. The I2S digital audio data is decoded and processed by MT8202,
