1.1 GENERAL GUIDELINES

1. SAFETY PREAUTIONS

2.PREVENTION OF ELECTRO STATIC DISCHARGE(ESD)TO 
ELECTROSTATICALLY SENSITIVE(ES)DEVICES

1. When servicing, observe the original lead dress. if a short circuit is found, replace all parts which have
been overheated or damaged by the short circuit.

2. After servicing, see to it that all the protective devices such as insulation barrier, insulation papers
shields are properly installed.

3. After servicing, make the following leakage current checks to prevent the customer from being exposed

to shock hazards.

Some semiconductor(solid state)devices can be damaged easily by static electricity. Such components
commonly are called Electrostatically Sensitive(ES)Devices. Examples of typical ES devices are integrated
circuits and some field-effect transistors and semiconductor chip components. The following techniques
should be used to help reduce the incidence of component damage caused by electro static discharge(ESD).

1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain
off any ESD on your body by touching a known earth ground. Alternatively, obtain and wear a commercially
availabel discharging ESD wrist strap, which should be removed for potential shock reasons prior to
applying power to the unit under test.

2. After removing an electrical assembly equipped with ES devices,place the assembly on a conductive
surface such as alminum foil, to prevent electrostatic charge buildup or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.

4. Use only an anti-static solder removal device. Some solder removal devices not classified as anti-static
(ESD protected)can generate electrical charge sufficient to damage ES devices.

5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES
devices.

6. Do not remove a replacement ES device from its protective package until immediately before you are
ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by
conductive foam, alminum foil or comparable conductive material).

7. Immediately before removing the protective material from the leads of a replacement ES device, touch
the protective material to the chassis or circuit assembly into which the device will be installed.
Caution
Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion
such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can
generate static electricity(ESD).

The laser diode in the traverse unit (optical pickup)may brake down due to static electricity of clothes or human

body. Use due caution to electrostatic breakdown when servicing and handling the laser diode.

Some devices such as the DVD player use the optical pickup(laser diode)and the optical pickup will be damaged

by static electricity in the working environment.Proceed servicing works under the working environment where

1. Put a conductive material(sheet)or iron sheet on the area where the optical pickup is placed,and ground the

3. The flexible cable may be cut off if an excessive force is applied to it.Use caution when handling the cable.

4.1.2.Human body grounding

1 Use the anti-static wrist strap to discharge the static electricity from your body.

safety_3 (1577x409x2 tiff)

4.1.3.Handling of optical pickup

1. To keep the good quality of the optical pickup maintenance parts during transportation and before
installation, the both ends of the laser diode are short-circuited.After replacing the parts with new ones,
remove the short circuit according to the correct procedure. (See this Technical Guide).

2. Do not use a tester to check the laser diode for the optical pickup .Failure to do so willdamage the laser
diode due to the power supply in the tester.

4.2. Handling precautions for Traverse Unit (Optical Pickup)

1. Do not give a considerable shock to the traverse unit(optical pickup)as it has an extremely high-precise
structure.

2. When replacing the optical pickup, install the flexible cable and cut is short land with a nipper. See the
optical pickup replacement procedure in this Technical Guide. Before replacing the traverse unit, remove
the short pin for preventingstatic electricity and install a new unit.Connect the connector as short times as
possible.

4. The half-fixed resistor for laser power adjustment cannot be adjusted. Do not turn the resistor.

Servo Controller

The servo control is accomplished through the servo DSP (Servo Digital Signal Processor) and its accessory I/O circuits. This servo
DSP is capable of performing complex operations an d also provides a friendly interface for the system controller. By issuing type
1 and type 2 commands from the system controller, the servo DSP can accomplish various complicated servo control functions,
such as tracking, seeking and MT1336/MT1376 chip register programming. As for the servo I/O circuits, it provides interface
between the input servo signals and the Servo DSP. It has built-in ADCs to digitize the servo control signal and DACs to provide
signals for the actuator and sledge motor. It also has a serial interface to communicate with the MT1336/MT1376 chip.

Analog Front End

The analog front end contains a data slicer circuit and a data PLL circuit. The RF analog signal from MT1336/MT1376 is
quantized by the data slicer to form the EFM/EFM+ bit stream, from which the channel bit clock is extracted by the data PLL.The
EFM/EFM+bit stream and bit clock are then output to DPU for channel bit processing.

DPU

Data path unit (DPU) provides protection on data with lost synchronization patterns and demodulates EFM/EFM+ bit stream into
the channel raw data that will be corrected by the decoder. The synchronization protection makes data after the synchronization
pattern to be extracted even if the synchronization pattern is not found.

Spindle Controller

The sp indle controller is used to control disc spindle motor. It includes a varipitch CLV clock generator, a CLV/CAV controller,
and a PWM generator. The varipitch CLV clock enerator generates a reference colck for the speed of operation. The CLV/CAV

controller changes the mode and speed of operation according to servo register setting. The PWM generator generates
pulse-width-modulated signal to drive disc spindle motor driver.

CSS/CPPM

The CSS/CPPM module provides functions necessary for decoding discs conforming to CSS/CPPM specification.

System Parser

The system parser is used to help the system controller to decode DVD/SVCD/VCD bitstream just after the channel decoder
performing error correction. Acting as a DMA master, it moves bitstream data from RSPC buffer to video, audio, or sub-picture
buffer according to system controller request. It also decrypts the scramble data of the CSS/CPPM sectors. Another function of
system parser is providing system controller/DSP a DRAM memory copy controller to enhance system controller/DSP performance.

Video Decoder

The primary function of MT1379 is to support MPEG1 and MPEG2 video decoding. The video decode engine comprises of
variable length decoder (VLD), inverse transformer (IT), motion compensator (MC), and block reconstructor (BR). The video
decode engine decodes the variable length encoded symbols in MPEG bitstream and performs inverse scan, inverse
quantization, mismatch control and inverse discrete cosine transform onto the variable length decoded data. The motion
compensator fetches prediction data from reference picture buffer according to motion vectors and motion prediciton mode for P
and B pictures. Finally, the block reconstructor combines both the results of inverse transformer and motion compensator to derive
the reconstructed image macroblock and write back to picture buffer.

The video decode engine can also support JPEG and BMP file decoding by common image compression hardware kernels.

Video Output

The Video Output unit contains Video Processor, SPU, OSD, Cursor, TV encoder units, it performs

Merging the video data, SPU, OSD and cursor

The Video Processor unit controls the transfer of video data stored in the DRAM to an internal or external TV encoder. It uses
FIFOs to buffer outgoing luminance and chrominance data, and performs YUV420 to YUV422 conversion and arbitrary
vertical/horizontal decimation/interpolation, from 1/4x to 256x. With this arbitrary ratio scaling capability, the Video Processor
can perform arbitrary image conversion, such as PAL to NTSC, NTSC to PAL, MPEG1 to MPEG2, Letterbox, Pan-Scan
conversion or zoom in, zoom out. It is also capible of interlace to progressive conversion.

The Video Processor unit performs the following functions:

§

Requests and receives the decoded picture data from the picture buffer in external DRAM for display

§

Resample vertical data to create 4:2:2 sample format

§

Optionally performs vertical/horizontal resampling of both luminance and chrominance data

§

Performs optional Gamma correction, luminance/chrominance adjustment, and edge enhancement

The V ideo Processor unit contains two 2-tap vertical filters for luminance and chrominance . These filters are used to
interpolate and reposition luminance and chrominance line to improve picture quality. These filters are capble of generating
up to eight, unique subline value between two consecutive scan lines. The generation of lines depends on the ratio between
the height of the source image and the target image. In applications where DRAM bandwidth are critical the filters can be
configured as simple line-repeating to reduce the DRAM bandwidth required.

The Video Processor unit integrates two separate horizontal postprocessing filter, a simple 2-tap linear horizontal filter and
an 8-tap programmable filter. These filters are provided for scaling images horizontally along the scan line. These two filters
is capable of generating up to eight, unique subpixel values between two consecutive pixels on a scan line. The generation
of pixels depends on the ratio between the width of the source image and the target image.

This is a hardware sub-picture decoder. It decodes the compressed SPU image bitstream and CHG_COLCON commands
according to SPU header information previously decoded by system controller. The SPU module also allows two SPU
objects to be displayed at the same time. SPU image is blended with main video stream.

OSD

The OSD module can operate with 2/4/16/256-color bitmap format (1/2/4/8 bits), and 16/256 color RLC format, all have 16
levels of transparency. In addition, it accepts an special WARP mode, which inserts one programmable RLC code in the
bitmap to reduce the image size stored in DRAM. It also features automatic shadow/outline generation in 2-color mode, 2
Hilight areas, 1 ChangeColor area and 1 OSDVoid area. One OSD area can occupy the full or a partial screen, or multiple
OSDs can occur in a screen at the same time, only if they don't occupy the same horizontal line. The output image is
blended with the video-SPU mixed stream.

Cursor

A hardware cursor generator is integrated in Video Output Unit. The cursor image is a 32x32 4-color bitmap image, each
colors are programmable. Cursor can be enlarged by 2 in both vertical and horizontal directions. Cursor image is multiplexed
with video-SPU-OSD mixed stream.

Audio Interface

Audio interface consists of Audio Output Interface and Microphone Input Interface.

Audio Output Interface

The MT1379 can support up to 8 channel audio outputs. The output formats can be 16, 24, or 32-bit frames. Left alignment,
right alignment, or I2S formats are all supported.

With built-in PLL, MT1379 can provide the audio clock (ACLK) for external audio DAC at 384Fs, where Fs is usually 32KHz,

44.1KHz, 48KHz, 96KHz, or 192KHz. ACLK can also be programmed to be from outside MT1379. When ACLK is input to
MT1379, the frequency could be 128*n Fs, where n is from 1 to 7.

Audio raw (encoded) data or cooked (decoded) data can be output on a single line using S/PDIF interface. The output slew
rate and driving force of this pad are programmable.

Microphone Input Interface

The MT1379 provides a microphone input interface. Two independent microphones’ data could be input to the MT1379.
There are two independent digital volume control for these two input channels. The input data formats can also be left
alignment, right alignment, or I2S formats.

MT1379

System Controller

MT1379 uses an embedded Turbo-8032 as System Controller and provide ICE interface to increase the feasibility of F/W
development. Also, MT1379 includes an build-in internal 373 to latch lower byte address from 8032 Port 0 and provide a
glue-logic free solution. MT1379 supports up to 1M X 16 bits Flash ROM to store 8032 code, H/W related data, User data, etc.
F/W upgrade can be achieved either by debug interface or by disk.

DESCRIPTION

The Hyundai HY57V641620HG is a 67,108,864-bit CMOS Synchronous DRAM, ideally suited for the main memory applications which
require large memory density and high bandwidth. HY57V641620HG is organized as 4banks of 1,048,576x16.

HY57V641620HG is offering fully synchronous operation referenced to a positive edge of the clock. All inputs and outputs are synchro­nized with the rising edge of the clock input. The data paths are internally pipelined to achieve very high bandwidth. All input and output
voltage levels are compatible with LVTTL.

Programmable options include the length of pipeline (Read latency of 2 or 3), the number of consecutive read or write cycles initiated
by a single control command (Burst length of 1,2,4,8 or Full page), and the burst count sequence(sequential or interleave). A burst of
read or write cycles in progress can be terminated by a burst terminate command or can be interrupted and replaced by a new burst

read or write command on any cycle. (This pipelined design is not restricted by a `2N` rule.)

NOTE:

When repairing the power amplifying board, make sure that the IC is fixed to the big radiator board closely
and rightly without any inclination in assembling the Power IC N407, N408, N409 and N410. A silicon oiled
mica spacer needs to be placed between the IC and the big radiator board. When fixing the screws of the
Power IC N407, N408, N409 and N410, the insulating spacers need to be placed between the screws and
the Power IC. A multimeter can be used to detect whether the insulation is effective or not. Otherwise, a
short circuit may be resulted to burn out the Ics.
