1. INTRODUCTION
1.1. Purpose
This manual provides the information necessary to repair, calibration, description and download the features of
the GS290.
1.2. Regulatory Information
1.2.1. 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 you’re your telecommunications services. System users are
responsible for the security of own system. There are may 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.
1.2.2. 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.
1.2.3. 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 GS290 or compatibility with the
network, the telephone company is required to give advanced written notice to the user, allowing
the user to take appropriate steps to maintain telephone service.
1.2.4. Maintenance Limitations
Maintenance limitations on the GS290 must be performed only at the LGE or its authorized agents.
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.

3.3. Power management IC
SM-POWER is a further step on the successful E-Power product line with enhanced and optimized functionality.
3.3.1. General Description
SM-POWER features a baseband supply concept with a DC/DC step-down converter cascaded by two linear
regulators
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 S-GOLD baseband device it
is suitable for the S-GOLDlite 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.
–SM-POWER’s DC/DC converter makes up to 40 % reduction of battery current for smart phone functions (e.g.
organizer functions, games, MP3 decoding) possible.
– SDBB has high efficiency up to 95% and also a power save mode.
– Memory Interface is directly supported by the SDBB
– SDBB can also act as main supply voltage for E-GOLD+ or S-GOLDlite baseband devices.
– For S-GOLD two linear regulators for DSP and Core are cascaded after the SDBB.
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
• Backlight LEDs driver with current selection and PWM dimming function
• Two single LED driver outputs for signaling
• Vibrator driver with adjustable voltage
• Fully controlable by software via I2C – Bus
SM-POWER supports the standby power-down concept of S-GOLD by temporarily switching off the linear
regulator for the DSP during mobile standby whenever this subsystem is not used. In this phase the ARM
controller and most peripherals including parts of the on-chip SRAM are kept powered-up with power being
supplied by the other linear regulator.
SM-POWER includes a fully differential audio amplifier able to drive loads down to a nominal value of 8 Ohm for
usage in hands-free phones and for ringing
– 450 mW maximum output power
– adjustable gain
– mute switch SM-POWER also integrates a charging function for Li-Ion, Li-Polymer batteries
– click and pop -protection SM-POWER also integrates a charging function for Li-Ion, Li-Polymer batteries
– Precharge current source with two current levels
– Constant current / constant voltage charging with 3 different termination voltages
– Programable charge current limitation for use with different batteries
– Freely programable pulse charging to reduce the thermal power dissipation in the constant voltage
charging phase
– Top-off charge current sensing SM-POWER completes the USB interface of S-GOLD
• Temperature and battery voltage sensors
• Interrupt channels for peripherals
• System debug mode
– Regulated voltage for S-GOLD USB interface including reverse current and overvoltage protection
– Switch to supply USB pull-up resistor
• VQFN 48 package with heat sink and non-protruding leads
• Compatible with the Infineon E-GOLD+ V2 and V3
– Mini-host pull down resistor functionality
– Charge pump with internal switching capacitor for USB host VBUS supply voltage SM-POWER fully supports
LED and Vibra Motor functionality
– no external components needed
– driver for backlight LEDs adjustable in steps up to 140mA and with soft turn on and off by PWM dimming
– two driver outputs for single LEDs for precharge indication and signaling with i.e. change of colour

3.3.2. Charging
3.4. Power ON/OFF
The bq25040 has a single power output that charges the battery. A system load can be placed in parallel with
the battery.The charge current is programmed using the ISET and EN/SET inputs. The charge current is
programmable to USB100, USB500 or a user programmed charge current up to 1.2A. Additionally, a 4.9V +/-3%
50mA LDO is integrated into the IC for supplying low power external circuitry. The one-wire interface (EN/SET)
is available to place the bq25040 into Test Jig Mode. In Test Jig Mode, the output is regulated at 4.2V and can
be used without a battery.The bq25040 has a single power output that charges the battery.. Either a 1-cell
Li-Ion or Li-Ion-Polymer battery with 4.1, 4.2 or 4.4 Volts may be used.

3. TECHNICAL BRIEF
Input ON is a power-on input for SM-POWER with 2 active high levels (see Figure 6). It might be triggered by a
push button or by the RTCOUT output of the S-GOLD device as well. To detect if the push-button is pressed
during system operation the logical level at pin ON or its change (if Bit 1 EION in INTCTRL2 is asserted) is
recorded in bit LON of the ISF register. If the high level of voltage at pin ON does not reach VIHdet (Vbat-0.8 ~
Vbat-0.3) the above-mentioned bit won’t be set.
To support Remote power on function for factory mass production, applied an analog switch as following
figure. As monitoring the RPWRON and Key matrix KP_OUT(2) & KP_IN (6), GS290 system recognize whether
remote power on or End-key pushed
3.5. SIM & uSD interface
GS290 supports 1.8V & 2.9V plug in SIM, SIM interface scheme is shown in (Figure 8).
SIM_IO, SIM_CLK, SIM_RST ports are used to communicate with BBP(S-Gold3) and the SIM power supply
enabled by PMIC.

The AAT3169 is a write-only single wire interface. It provides access to up to 32 registers that control device
functionality.In this system, two sets of pulse trains are transmitted via the SPIF pin. The first pulse set is used to
set the desired address. After the bus is held high for the address hold period, the next pulse set is used to write
the data value. After the data pulses are transmitted the bus is held high again for the data hold period to
signify the data write is complete. At this point the slave device latches the data into the address that was
selected by the first set of pulses. The protocol for using this interface is described in the following subsection.

The MAX14526 is a complete solution for multiplexing USB, UART and audio on a single mini/micro USB
connector. It contains an internal method for determining the device connected and uses an I2C bus for
control.
The switch will multiplex multiple inputs (USB, UART,Microphone, Stereo and Audio) on one mini/microUSB
connector. The USB and UART inputs support Hi-Speed USB and the audio inputs feature negative rail signal
operation allowing simple dc coupled headset speakers. The VB connection is protected against faults up to 28
volts. There is an internal device detection method which uses the USB ID signal pin and the voltage on VBUS.
Each accessory will have a unique detection based on resistor values and voltage on VBUS. The host
microprocessor uses I2C to control the switch position as well as read the results of the accessory detection.
The MAX14526 will also detect USB chargers including dedicated chargers (D+/D- shorted) and high power
host/hub chargers.

3.17. Receiver part
3.18. Transmitter part
Figure 25 Receiver part block diagram
The constant gain direct conversion receiver contains all active circuits for a complete receiver chain for
GSM/GPRS/EDGE (see Figure 25). The GSM850/900/DCS1800/ PCS1900 LNAs with balanced inputs are fully
integrated. No inter-stage filtering is needed. The orthogonal LO signals are generated by a divider-by-four for
GSM850/900 band and a divider-by-two for the DCS1800/PCS1900 band. Down conversion to baseband
domain is performed by low/high band quadrature direct down conversion mixers. The baseband chain
contains a LNB (low noise buffer), channel filter, output buffer and DC-offset compensation. The 3rd order low
pass filter is fully integrated and provides sufficient suppression of blocking signals as well as adjacent channel
interferers and avoids anti-aliasing through the baseband ADC. The receive path is fully differential to suppress
on-chip interferences. Several gain steps are implemented to cope with the dynamic range of the input signals.
Depending on the baseband ADC dynamic range, single- or multiple gain step switching schemes are
applicable. Furthermore an automatic DC-offset compensation can be used (depending on the gain setting) to
reduce the DC-offset at baseband-output. A programmable gain correction can be applied to correct for front
end- and receiver gain tolerances.
The GMSK transmitter supports power class 4 for GSM850 and GSM900 as well as power class 1 for DCS1800
and PCS1900. The digital transmitter architecture is based on a very low power fractional-N Sigma-Delta
synthesizer without any external components (see Figure39). The analog I/Q modulation data from the
baseband is converted to digital, filtered and transformed to polar coordinates. The phase/frequency signal is
further on processed by the Sigma-Delta modulation loop. The output of its associated VCO is divided by four
or two, respectively, and connected via an output buffer to the appropriate single ended output pin. This
configuration ensures minimum noise level. The 8PSK transmitter supports power class E2 for GSM850 and
GSM900 as well as for DCS1800 and PCS1900. The digital transmitter architecture is based on a polar
modulation architecture, where the analog modulation data (rectangular I/Q coordinates) is converted to
digital data stream and is subsequently transformed to polar coordinates by means of a CORDIC algorithm. The
resulting amplitude information is fed into a digital multiplier for power ramping and level control. The ready
processed amplitude signal is applied to a DAC followed by a low pass filter which reconstructs the analog
amplitude information. The phase signal from the CORDIC is applied to the Sigma-Delta fractional-N
modulation loop. The divided output of its associated VCO is fed to a highly linear amplitude modulator,
recombining amplitude and phase information. The output of the amplitude modulator is connected to a
single ended output RF PGA for digitally setting the wanted transmit power. The PA interface of SMARTi-PM
supports direct control of standard dual mode power amplifiers (PA’s) which usually have a power control input
VAPC and an optional bias
Figure 26 Transmitter part block diagram
control pin VBIAS for efficiency enhancement. In GMSK mode, the PA is in saturated high efficiency mode and is
controlled via its VAPC pin directly by the baseband ramping DAC. In this way both up- / down-ramping and
output power level are set. In 8PSK mode, the ramping functionality is assured by an on-chip ramping
generator, whereas output power is controlled by the PGA’s as described above.

3.20. Front End Module control
3.19. RF synthesizer
The transceiver contains a fractional-N sigma-delta synthesizer for the frequency synthesis in the RX operation
mode. For TX operation mode the fractional-N sigma-delta synthesizer is used as Sigma-Delta modulation loop
to process the phase/frequency signal. The 26MHz reference signal is provided by the internal crystal oscillator.
This frequency serves as comparison frequency of the phase detector and as clock frequency for all digital
circuitry.The divider in the feedback path of the synthesizer is carried out as a multi-modulus divider (MMD).
The loop filter is fully integrated and the loop bandwidth is about 100 kHz to allow the transfer of the phase
modulation. The loop bandwidth is automatically adjusted prior to each slot (OLGA2). To overcome the
statistical spread of the loop filter element values an automatic loop filter adjustment (ALFA) is performed
before each synthesizer startup. The fully integrated quad-band VCO is designed for the four GSM bands (850,
900, 1800, 1900 MHz) and operates at double or four times transmit or receive frequency. To cover the wide
frequency range the VCO is automatically aligned by a binary automatic band selection (BABS) before each
synthesizer startup.
Implemented in the S-Gold3 (FL500) are two outputs which are VC1, VC2 for direct control of front end modules
with two logic input pins to select RX and TX mode as well as low and high band operation..

Two separate Heterojunction Bipolar Transistor(HBT) PA blocks are fabricated onto InGaP die; one supports the
GSM850/900 bands, the other supports the DCS1800 and PCS1900 bands. Both PA blocks share common
power supply pins to distribute current. The InGaP die, the silicon die, nad the passive components are
mounted on a multi layer laminate substrate. The assembly is encapsulated with plastic overmold.
RF input and output ports are internally matched to 50ohm to reduce the number of external components
Extremely low leakage current(2.5uA) maximizes handset standby time. Band select(BS) circuitry select GSM
transmit frequency band(logic0) and DCS/PCS transmit frequency(logic1). MODE circuitry selects GMSK
modulation (logic0) or EDGE modulation(logic1). VRAMP controls the output power for GMSK modulation and
provides bias optimization for EDGE modulation depending on the state of MODE control.

Figure 28 PAM schematic
The integrated multi-function(MFC) provides envelope amplitude control in GMSK mode, reducing sensitivity
to input drive, temp, power supply, and process variation. In EDGE mode, the MFC configures the PA for fixed
gain, and provides the ability to optimize the PA bias operation at different power levels, This circuitry regulates
PA bias conditions, reducing sensitivity to temp., power supply, and process variation. The Enable input
signal(pin8) provides a standby state to minimize battery drain..
