1.1 GENERAL GUIDELINES

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.

5.3.1 Protection of the LD(Laser diode)

Short the parts of LD circuit pattern by soldering.

5.3.2 Cautions on assembly and adjustment

Make sure that the workbenches,jigs,tips,tips of soldering irons and measuring instruments are

grounded,and that personnel wear wrist straps for ground.

Open the LD short lands quickly with a soldering iron after a circuit is connected.

Keep the power source of the pick-up protected from internal and external sources of electrical
noise.

Refrain from operation and storage in atmospheres containing corrosive gases (such as H2S,SO2,

NO2 and Cl2)or toxic gases or in locations containing substances(especially from the organic silicon,cyan,

formalin and phenol groups)which emit toxic gases.It is particularly important to ensure that none of the

above substances are present inside the unit.Otherwise,the motor may no longer run.

4 Banks x 1M x 16Bit Synchronous DRAM

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.)

FEATURES

• Single 3.3±0.3V power supply

• All device pins are compatible with LVTTL interface

• JEDEC standard 400mil 54pin TSOP-II with 0.8mm
of pin pitch

• All inputs and outputs referenced to positive edge of
system clock

• Data mask function by UDQM or LDQM

• Internal four banks operation

Note)

• Auto refresh and self refresh

• 4096 refresh cycles / 64ms

• Programmable Burst Length and Burst Type

- 1, 2, 4, 8 or Full page for Sequential Burst

- 1, 2, 4 or 8 for Interleave Burst

• Programmable CAS Latency ; 2, 3 Clocks

Based on MediaTek’s world-leading DVD player SOC architecture, the MT1389 is the 3
player SOC. It integrates the MediaTek 2
decoder.

The progressive scan of the MT1389 utilized a proprietary advanced motion-adaptive de-interlace algorithm to
achieve the best movie/video playback. It can easily detect 3:2/2:2 pull down source and restore the correct
original pictures. It also supports a patent-pending edge-preserving algorithm to remove the saw-tooth effect.
