1. INTRODUCTION

1.1.Purpose

1. INTRODUCTION

This manual provides the information necessary to repair, calibration, description and download the

features of the GC900.

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 GC900 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 GC900 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.

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

GC900 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.

3.2.1 General description

3. BB Circuit Technical brief

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 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.

3.3 Power management IC

3.3.1 General Description

SM-POWER is a highly integrated Power and Battery Management IC for mobile handsets. It has

been specially designed for usage with S-Gold3. Although optimized for usage with the Infineon

SGOLD

baseband device it is suitable for the S-GOLD lite and the E-GOLD+ baseband devices as well.

It also supports the cellular RF devices like SMARTi-DC, SMARTi-DC+, SMARTi-SD and the

Bluemoon Single, Infineon’s single chip solution for Bluetooth. If used with S-GOLD3 it provides all

power supply functions (except for the RF PA) for a complete advanced GSM Edge smart phone

minimizing external device count.

Block Description

• Highly efficient step-down converter for main digital baseband supply including Core, DSP and

memory interface (External Bus Unit).

• Support of S-GOLD standby power-down concept

• Low-drop-out (LDO) regulators for Flash and mobile RAM memory devices

• Voltage independent switching of two SIM cards

• LDO regulators for baseband I/O supply

• LDO regulator for analog mixed-signal section of S-GOLD

• Low-noise LDO regulators for RF devices

• Supply for Bluemoon Single, Infineon’s single chip solution for Bluetooth

• Audio amplifier 8 Ohms for handsfree operation and ringing

• Charge Control for charging Li-Ion/Polymer batteries under software control

• Pre-charge current generator with selectable current level

• RTC regulator with ultra-low quiescent current

• USB interface support for peripheral and mini-host mode
