1. INTRODUCTION
1. INTRODUCTION
1.1.Purpose
This manual provides the information necessary to repair, calibration, description and download the
features of the GW520.
1.2.Regulatory Information
A. Security
Toll fraud, the unauthorized use of telecommunications system by an unauthorized part (for example,
persons other than your company’s employees, agents, subcontractors, or person working on your
company’s behalf) can result in substantial additional charges for your telecommunications services.
System users are responsible for the security of own system.
There might be risks of toll fraud associated with your telecommunications system. System users are
responsible for programming and configuring the equipment to prevent unauthorized use. LGE does
not warrant that this product is immune from the above case but will prevent unauthorized use of
common carrier telecommunication service of facilities accessed through or connected to it. LGE will
not be responsible for any charges that result from such unauthorized use.
B. Incidence of Harm
If a telephone company determines that the equipment provided to customer is faulty and possibly
causing harm or interruption in service to the telephone network, it should disconnect telephone
service until repair can be done. A telephone company may temporarily disconnect service as long as
repair is not done.
C. Changes in Service
A local telephone company may make changes in its communications facilities or procedure. If these
changes could reasonably be expected to affect the use of the GW520 or compatibility with the net
work, the telephone company is required to give advanced written notice to the user, allowing the user
to take appropriate steps to maintain telephone service.
D. Maintenance Limitations
Maintenance limitations on the GW520 must be performed only by the LGE or its authorized agent.
The user may not make any changes and/or repairs expect as specifically noted in this manual.
Therefore, note that unauthorized alternations or repair may affect the regulatory status of the system
and may void any remaining warranty.

1. INTRODUCTION
E. Notice of Radiated Emissions
This model complies with rules regarding radiation and radio frequency emission as defined by local
regulatory agencies. In accordance with these agencies, you may be required to provide information
such as the following to the end user.
F. Pictures
The pictures in this manual are for illustrative purposes only; your actual hardware may look slightly
different.
G. Interference and Attenuation
GW520 may interfere with sensitive laboratory equipment, medical equipment, etc. Interference from
unsuppressed engines or electric motors may cause problems.
H. Electrostatic Sensitive Devices
ATTENTION
Boards, which contain Electrostatic Sensitive Device (ESD), are indicated by the sign. Following
information is ESD handling:
• Service personnel should ground themselves by using a wrist strap when exchange system boards.
• When repairs are made to a system board, they should spread the floor with anti-static mat which is
also grounded.
• Use a suitable, grounded soldering iron.
• Keep sensitive parts in these protective packages until these are used.
• When returning system boards or parts like EEPROM to the factory, use the protective package as
described.

3. BB Circuit Technical brief
3.2.1 General description
S-GOLD®3H is a HSDPA/WCDMA/EDGE/GPRS/GSM system in package solution consisting of a
mixed signal baseband IC combined with a 3G coprocessor IC, providing all analog and digital
functionality for a dual mode mobile phone in a single chip.
Both ICs building up the S-GOLD®3H SiP are manufactured in infineon Technologies` 1.35V 90nm
CMOS technology to meet the ever increasing demands of the market for feature rich and high
performance terminals at low costs.
The chip will support the FR, EFR, HR and AMR-NB vocoding.
S-GOLD®3H support multi-slot operation modes HSCSD (up to class 10), GPRS for high speed data
application (up to class 12), EGPRS (up to class 12) and DTM(class11) without additional external
hardware.
3.2.2. Block Description
z Processing core
- ARM926EJ-S 32 bit processor core for controller functions. The ARM926EJ-S includes an MMU,
and the Jazelle Java extension for Java acceleration and a MOVE co-processor to accelerate
Motion Estimation algorithms with based video encoding schemes..
- TEAKLite DSP core

z Shared Memory Block
1.5K x 32bit Shared RAM(dual ported) between controller system and TEAKLite®.
z Controller Bus system
The processor cores and their peripherals are connected by powerful buses.
- Multi-layer AHB for connecting the ARM and the other master capable building blocks with the
internal and external memories and with the peripheral buses.
- An FPI-Bus for connecting GSM peripherals, called hereafter FPI3 bus.
- A controller FPI bus for connecting the low performance controller peripherals such as keypad
etc. called hereafter fPI2 bus.
- FPI2 and FPI3 are connected asynchronously to the AHB buses. 1 DMA controller with
8channels offloads the controller from data transfers.
- 2 AHB Lite buses for connecting multi-media and high performance peripherals, called
AHB_PER1 and AHB_PER2 hereafter. These peripheral buses are connected to the multi-layer
AHB ‘backbone’ by asynchronous, burst capable AHB2AHB bridges which are shared between
accessing masters.
- The DMA controller is enabled to access AHB_PER1 by use of its first master interface and
AHB_PER2 by its second master interface.
z TEAKLite® Bus System
- 1 TEAKLite® data bus for connecting the TEAKLite® data memory and the TEAKLite® peripherals.
Also the data bus is connected into the controller system via shared RAMs to the FPI3 bus.
- 1 TEAKLite® program bus for connecting the TEAKLite® program memory to the TEAKLite®.
z Clock system
The clock system allows widely independent selection of frequencies for the essential parts of the S-
GOLD®3H. Thus power consumption and performance can be optimized for each application.
z Functional Hardware block
- CPU and DSP Timers
- MOVE coprocessor performing motion estimation for video encoding algorithms
(H.263, MPEG-4)
- Programmable PLL with four additional phase shifters for system clock generation
- GSM Timer Module that off-loads the CPU from radio channel timing
- GMSK / 8-PSK Modulator according to GSM-standard 05.04 (5/2000)
· GMSK Modulator: gauss-filter with B*T=0.3
· EDGE Modulator: 8PSK-modulation with linearized GMSK-Pulse-Filter
