Perform the Ohm measurements by using the DMM instrument (Fluke).
Note!
Note! Connect the Black probe to the X2405_PIN 9 (GND).
The Battery must be removed from the Phone during this test.
Current Consumption Test
Step 1:
Insert a Local SIM Card and use the phone with the Normal SW (SSW).
Use Dummy Battery connected to Power Supply Channel 1 (VBATT).
Instrument settings: Voltage: 3.8 Volt, Limiter 3A.
Note! The Dummy Battery should have approximately 120K Ohm resistance between GND
and BDATA.
Measure the current consumption when Phone is turned off.
Take a note of the current consumption at Power Supply Channel 1 (VBATT).
The Current consumption in off mode should be less than 1mA.
If more than 1mA go to Dead Phone Problems part 1 TRS guide.

Charger Control
A programmable charger is used for battery charging. Limits can be set for the output
voltage at CHSENSE- and the output current from DCIO through the sense resistor to
CHSENSE-. The programmable charger is enabled or disabled by the assertion/negation of
the external signal DCIO. Parts of the programmable charger are activated and
deactivated depending on the level of VBAT. The rest of the programmable charger is
activated and deactivated through I2C.
The programmable charger supports the following functions:
• Constant current charging
• Constant voltage charging
• Trickle ch a r ging
• PWM controlled charging
• Over-voltage and over current detection
• Watchdog termination
• DCIO assertion/removal detection
• Voltage and cur r ent measure function s
• Low resistive path (reverse mode)
The programmable charger is able to control the voltage and limit the current to a load
seen at CHSENSE-. The programmable charger can also be run in PWM mode to turn the
charging on and off in accordance with the particular period and duty cycle. When the
charging is on, it is set to the current and voltage selected by I2C.
A low resistive path from VBAT to DCIO can be formed when DCIO is not detected. When
this setting is done in the appropriate registers, a lowering of CHREG to 0 V turns on the
external pass device. The pass device is automatically turned off whe n an external source
is detected on DCIO, or when the watchdog termination block times out. The watchdog
termination block must be active when the external switch is enabled, both in normal
charging mode and in the low resistive path mode. The watchdog is set through the serial
interface, and if it has not been set again before timeout, the watchdog turns off the
external switch. The watchdog is disregarded during trickle charging. When no battery is
present, the system can be booted and supplied from DCIO by
applying the correct voltage on DCIO.
USB Charger
The analog baseband controller contains a standalone USB charger.
The USB charger has a separate input and incorporates full functionality during low VBAT.
The programmable charger supports the following functions:
• Trickle ch a r ging
• Constant current charging
• Watchdog termination
• Trickle LED indication
• VBUS assertion/removal detection
Resistance Identification and Temperature Measurement
The resistance identification mode utilizes the constant current source to feed the battery
data output while monitoring the voltage at the battery data node with general purpose
ADC the conversion is started through I2C.

CODEC Overview
The CODEC is encoding analog audio signals and analog voice signals into digital signals
using Analog to Digital converters (ADCs). This is done in the coder section of the CODEC,
also named the TX path (transfer section). The CODEC is also decoding digital audio
signals and digital voice signals into analog signals using DACs. This is done in the
decoder section of the CODEC, also named the RX path (receiver section).
CODEC Block Schematic:
CODEC CCO Voltage Source
There is an internal voltage source CCO that provides the necessary drive current for
electret microphones. The voltage source is I²C programmable to 2.2 V or 2.4 V. The
source can be disabled during standby. A typical use case with a microphone connected to
MIC1 and the CCO is shown in picture below.
Earphone Amplifier
The earphone amplifiers (BEARP and BEARN) are mainly intended to be differentially
configured and drive a low impedance dynamic transducer (earpiece) but they can also be
single ended configured. The BEARP and BEARN amplifiers can be powered down by the
I2C. The amplifiers can exhibit high impedance to 1.4V or low impedance to ground when
powered-down. Fifty-one gains are available for BEARP and BEARN: from +15dB down to
–60dB in 1.5dB steps. When the BEARP and BEARN outputs are operating in differential
mode, an I²C selectable bit must invert one of the inputs.
FUNCTIONAL OVERVI EW
Speaker Amplifier
The speaker amplifiers, SPKRP and SPKRN, are intended to drive a low impedance (8ƻ)
speaker in a differential mode or to be used as a stereo configured line output amplifier
supporting external high power amplifiers. The output buffer shall exhibit low impedance
to ground when powered-down and the current consumption shall be minimal. When the
SPKRP and SPKRN outputs are operating in differential mode, an I²C selectable bit must
invert one of the inputs.

Digital Baseband Controller (CPU)
N2010 (Kajsa)
This component is not replaceable on SL 4 because Baseband calibration is required.
The Digital Baseband Controller is divided in two subsystems: Access and Application
Access Subsystem
All modem functionality in the digital baseband controll er resid es in the Access subsystem.
This includes EDGE/GPRS/GSM interface, WCDMA interface, USB, IrDA, and other
peripheral modules. The control CPU is an ARM926 and a DSP is used for signal processing
and layer one control code.
The main communication between the blocks in the Acce ss subsystem is done through the
Advanced High-performance Bus (AHB) matrix, which is a set of control buses connecting
the different parts together. A block called Syscon is responsible f or distri buting clocks and
resets to all parts of the Access subsystem. This block is under SW control. The Access
subsystem is connected to the Shared EMIF, an interface for communication with an
external SDRAM. The Shared EMIF is shared between the Access subsystem and the
Application subsystem.
Access Subsystem of the Digital Baseband Controller:
Application Subsystem
The Application subsystem contains functionality related to functions such as MMI,
graphics, audio and memory media. The control CPU is an ARM926 with three external
memory interfaces, one shared with the Access subsystem and two dedicated for the
Application subsystem. The Application subsystem contains several blocks. The main
communication between the blocks is done through the Advanced High performance bus
(AHB) matrix, whi ch is a se t of cont rol bu ses con nectin g the di fferen t parts. A block called
Syscon is responsible for distributing clocks and resets to all parts of the Application
subsystem. This block is under SW control. The Application subsystem is connected to the
Shared EMIF that is used for code execution or data storage. In addition, a dedicated EMIF
that support SDRAM or static memory like NOR, PsRAM or NAND are also available. The
Application EMIF is a general interface for communication with, for example external
SDRAM, PSRAM, NOR flash, NAND flash and companion chips

The functional blocks of the Digital Baseband Controller:
Keypad
The keypad interface block supports up to 30 keys with 65 columns and 6 rows and
operates in both scan and idle mode. The keypad scan is performed by software. Any
transition in the state of the column inputs is written directly to the register. The keypad
interface differentiates between single key presses, simultaneous presses of any keys with
a function key, and any key releases. The period between successive scans is
programmable over the range 5 ms to 80 ms, in 5 ms steps. During scan mode, the
keypad generates an interrupt whenever a valid keypad state change occurs (including a
release of any pressed keys). The scan function is disabled during system power-up. The
keypad is able to detect at least four simultaneous key presses. Not all combinations are
supported.
Radio Part
Antenna
The mobile system antenna interface connects the Wideband Code Division Multiple
Access (WCDMA) and Global System for Mobile Communication (GSM) input/output to
the antenna of the Mobile Phone. It is a bi-directional RF interface containing signals in the
range 800 MHz to 2.2 GHz. The mobile system antenna interface is the interface between
the Mobile Phone Radio Frequency (RF) input/output and the mobile system antenna. The
interface handles the GSM 850, EGSM 900, GSM 1800, GSM 1900 and WCDMA Band I, II
and V, RF inputs/outputs.
Mobile System Antenna Interface :
Radio Module N1200 (Tiger)
Front End
The Front End block connects the proper block in the radio system to the antenna. The
Front End has two inputs for EDGE/GSM/GPRS, one for low band (850/900 MHz) and one
for high band (1800/1900 MHz). The EDGE/GSM/GPRS power amplifier output is filtered
by the low pass filter in the Front End and then connected to the antenna through a switch.
In receive mod e, th e EDGE/GS M/GPR S sign al fr om the an tenna passe s thr ough the swit ch
to one of the four receive SAW filters. The SAW filter provides receive band selectivit y. In
GSM/GRPS/EDGE systems, transmit and receive operations are divided in time and the
switch connects the proper block in accordance with the mode of operation (that is,
transmit or receive; one at a time).
In WCDMA the transmit outputs from the WCDMA transceiver are filtered by an external
SAW filter that cleans up the spectrum. The SAW filter output is connected to the power
amplifier, one for each band. For power control, a sample of the transmit output is taken
by a directional coupler and converted to a DC level by the power detection circuit. This
signal is used to control the transmitter output power. The transmit sign al passes through
an isolator and then a duplexer. The duplexer output is selected by the switch in the Front
End for connection to the antenna. In WCDMA receive mode the signal from the antenna is
switched by the Front End to the correct duplexer. The output from the duplexer is
connected to the LNA input in the WCDMA receiver.
Transceiver
The transceiver is a multi-mode transceiver for WCDMA/EGDE/GPRS/GSM. The
EDGE/GPRS/GSM part of the transceiver use a digital baseband interface that is shared
between received and transmitted data. The receive interface is based on I and Q data
and the transmitter interface is based on envelope and frequency data. The WCDMA part
of the transceiver use differential analog in-phase and quadrature-phase interfaces, which
is an IQ-interface, in the receiver and the transmitter data paths.

Frequency Generation
The 26 MHz reference signal is used as the reference for the on-chip synthesizers. To
cover the required frequency range, the integrated Voltage Controlled Oscillator (VCO)
operates at twice the frequency for band 1800/1900/2100, and at four times the desired
frequency for band 800/900. The two synthesizers are controlled through the serial bus
from the access side of the digital baseband controller.
EDGE/GPRS/GSM Transmitter Part
Polar modulation transmitter architecture based on the direct phase/frequency
modulation/synthesizer architecture is implemented for GSM, GPRS and EDGE. This
architecture has the capability of generating both the GSM/GPRS constant envelope GMSK
modulation and the linear EDGE 8-PSK modulation in a very cost efficient way. The
motivation for a polar modulation transmitter architecture compared to traditionally linear
architectures is to reduce the output noise (thus eliminating the need for off-chip filters)
reduce the power consumption by utilizing non-linear switching analog signal processing
blocks, and to eliminate the need for an RF isolator.
In brief, the phase/frequency modulator in this polar modulation architecture is a sigmadelta controlled fractional-N frequency synthesizer with an additional frequency insertion
point after the loop filter at the input of the VCO. The Phase-locked Loop (PLL) has two
information inputs: the divider ratio in the feedback path and a direct path to the VCO.
The phase locked loop generates the radio frequency carrier including the phase
modulation information at the desired channel frequency.
WCDMA Transmitter Part
The WCDMA transmitter architecture is an on frequency linear direct up-conversion IQmodulator. The in-phase and quadrature-phase reconstruction filters are fully integrated
and a programmable gain amplifier implements the gain control. An external SAW filter
between the WCDMA circuit and the power amplifier is used to improve noise performance.
After the power amplifier, the signal is sent through an isolator and through the duplex
filter, which directs the transmit signal to the antenna connector through the antenna
switch. The supply voltage and bias of the power amplifier are adapted depending on the
output power to achieve high efficiency at every transmitter power level. A high efficiency
DC/DC converter regulates the supply voltage and the bias operation point is controlled by
a D/A-converter in the WCDMA radio circuit.
Ericsson RF 3300 Block Diagram:
FUNCTIONAL OVERVI EW
Receiver Part
The receiver architecture is a direct down-conversion zero-IF receiver with integrated lowpass filters. The complete receiver with seven Low Noise Amplifiers (LNAs), one for each
supported band, is integrated on chip. After the down-conversion, the in-phase and
quadrature-phase components are low pass filtered and if the receiver is in
EDGE/GPRS/GSM mode the signals are fed to the integrated high dynamic range sigmadelta A/D-converters.

Bluetooth and FM Radio
The Blt/FM Radio circuit combines Bluetooth and FM tuner functionality into one.
Bluetooth
The Bluetooth implementation is compliant with Bluetooth specification 2.1 + EDR.
The Bluetooth
2480 MHz. The same band is used for both transmission and reception. This gives 79
frequency channels.
Receiver
The Bluetooth section implements a low-IF receiver for Bluetooth modulated inpu t signals.
The radio signal is taken from a balanced RF input and amplified by an LNA. The mixers
are driven by two quadrature LO signals, which are locally generated from a VCO signal
running at twice the frequency. The I and Q mixe r output signa ls are ban d pass filtere d by
a poly-phase filter for channel filtering and image rejection. The output of the band pass
filter is amplified by a VGA to the optimal input range for the A/D converter. Further
channel filtering is done in the digital part. The digital part demodulates the GFSK, Ⱥ/4-
DQPSK or 8-DPSK coded bit stream by evaluating the phase information. RSSI data is
extracted. Overall automatic gain amplification in the receive path is controlled digitally.
The RC time constants for the analog filters are automatically calibrated on chip.

Transmitter
The transmitter uses the serial transmit data from the Bluetooth Controller. The
transmitter modulator converts this data into GFSK, Ⱥ/4-DQPSK or 8-DPSK modulated I
and Q digital signals for respectively 1, 2 and 3 Mbps transmission speed. These signals
are then converted to analog signals that are low pass filtered before up-conversion. The
carrier frequency drift is limited by a closed loop PLL.
FM Radio
FM Receiver
The receiver uses a digital low-IF architecture. The receive (RX) section integrates a low
noise amplifier (LNA) supporting the worldwide FM broadcast band (76 to 108 MHz). An
automatic gain control (AGC) circuit controls the gain of the LNA to optimize sensitivity
and rejection of strong interferers. An image-reject mixer down converts the RF signal to
low-IF. The quadrature mixer output is amplified, filtered and digitized with high resolution
analog-to-digital converters (ADCs). This advanced architecture allows the use of digital
signal processing (DSP) to perform channel selection, FM demodulation and stereo audio
processing.
Tuning
The receiver uses frequency synthesize r technolo gy inclu ding a completely in tegrate d VCO.
The frequency synthesizer generates the quadrature local oscillator signal used to
downconvert the RF input to a low intermediate frequency. The VCO frequency is locked to
the reference clock and adjusted with an automatic frequency control (AFC) servo loop
during reception. The tuning frequency is defined as: Freq (MHz) = Spacing (kHz) ×
Channel + Bottom of Band (MHz)
External Connectors
External units are connected to the transceiver by means of a 12-pin connector on the
phone.
System connector pin input/output overview:
Master Clock
(26 MHz)
The 26.00 MHz VCXO-based MCLK is distributed as a square wave signal from the
GSM/EDGE circuit. In order to have full control over the load on the MCLK, only the access
side of the digital baseband controller is allowed to request the MCLK. However, by
indirect means also the application side CPU can issue the request. A VCXO-based square
wave is also distributed to the WCDMA circuit, but is turned on only upon a command
from the digital baseband controller.
Real-time Clock
(32. 768 kHz)
A 32.768 kHz crystal oscillator provides a low frequency clock whenever the platform has
power. This clock is used to keep the Real-Time Clock (RTC) block functioning, so that the
platform can keep track of the time and date. The low frequency clock is generated in the
analog baseband controller and distributed to the digital baseband controller, and if
necessary to external devices like Bluetooth, FM radio and A-GPS.
A-GPS
The Assisted GPS functionality in the phone is realized with the Global Locate
Hammerhead GPS module. The Global Locate Hammerhead belongs to the Type 2 GPS
solutions. The PMB 2525 Hammerhead II GPS IC is a GPS single chip device containing a
complete radio frequency front-end as well as the signal processing functionality in a
single die. The device allows the usage of assistance data by supporting A-GPS (assisted
GPS) standards (RRLP, RRC, OMA SUPL). One of three serial interfaces, UART, I²C or SPI,
is used for communication with the host system.
Clock Reference Frequency
The platform provides two reference frequencies, a 32.768 kHz clock (RTCCLK) from the
Analog Baseband Controller, and a 26 MHz reference clock (SYSCLK) from the Digital
Baseband Controller. The RTCCLK is used by the phone real time clock function. The
RTCCLK is distributed to the A-GPS module as a logical square wave. SYSCLK is derived
from the reference modulation clock MCLK to the platform access system and is
distributed from the Digital Baseband Controller to the A-GPS module. This 26 MHz clock
is synchronized with the cellular network to an accuracy of ±0.1 ppm. Automatic
frequency updates can also cause large frequency corrections, with associated phase
discontinuities. In order to isolate the A-GPS module for the unstable effects of SYSCLK,
an external reference clock is required. This external reference frequency provided by a
TCXO is required to provide a clock with very high short term stability. The frequency of
the TCXO is calibrated against the cellular reference clock by the A-GPS module enabling
the use of a more economical less accurate TCXO.

FUNCTIONAL OVERVIEW

Clocks
Clock Distribution
The clocking for the access and application subsystems is separated. This means that the
subsystems can wake up or go to sleep mode independently. The access subsystem is
clocked by the 26 MHz Voltage Controlled Crystal Oscillator (VCXO) located in the
GSM/EDGE circuit. When the access subsystem has a job to do, the Master Clock (MCLK)
signal is requested from the RF part. Most other clocks needed within the access
subsystem are generated from the MCLK. Some minor parts like sleep timer and cable
detect use the 32 kHz real-time clock. The 32 kHz real-time clock clocks the application
subsystem, and all other internal clocks needed within the application subsystem are
generated from this clock. However, when audio is transferred between the application
and the access subsystems, the MCLK is used.
Interface and Control
The Interface and control consists of system timing and control. The control interface
includes a communication link where both data and control information are transferred
between platform and the A-GPS module. Data and command information is transferred
using a full-duplex Universal Asynchronous Receiver Transmitter (UART) interface.
Other control signals include the following:
• A GPIO or platform reset used as a reset signal (nRESET) to the GPS module.
• A Transmission On signal (TXON/ RX_HOLD), is used to indicate to the A-GPS module
when the ME is transmitting. The A-GPS modules receiver is disabled whilst the ME is
transmitting.
• A hardware timing pulse (GPSSTART/SYNC) providing the A-GPS module with a
highly accurate timing reference. The A-GPS is able to accurately synchronize its
GPS time to this reference pulse.
• A GPIO used as an enable (POWERON) signal to the GPS module.
• A GPIO used for power control for the GPS module.

A-GPS Block Diagram:
WLAN device or BT device gets the antenna is Packet Traffic Arbitration (PTA). WLAN LD
configures the PTA during startup of the WLAN device. All PTA parameters are stored in
GDFS. The PTA is configured to prioritize BT traffic if it is a BT high request. All WLAN
traffic should have priority before any BT traffic that is categorized as BT low requests.
WLAN Driver sends status events to BT Driver to inform about:
• WLAN startup and shutdown
• WLAN association and disassociation
• The current WLAN channel in use
In the cases of WLAN startup and shutdown the BT Logical Driver configures the BT Device
to request the antenna from PTA or not. BT LD also monitors if WLAN have any connection
running. In that case, BT avoids the BT frequencies mapping to the WLAN channel. WLAN
monitors if BT has started any BT Inquiry or page. If this happens any link loss
mechanisms should be temporary turned off for the BT Inquiry or page period.
Bluetooth and WLAN PTA Mechanism:
WLAN (Wi-Fi)
This WLAN module is based on the new Marvell 88W8686 chipset. WLAN module is
designed to support IEEE 802.11a or 802.11g payload data rates of 6, 9, 12, 18, 24, 36,
48 and 54 Mbps, as well as 802.11b data rates of 1, 2, 5.5 and 11 Mbps. For security the
WLAN module supports the IEEE 802.11i security standard through implementation of the
Advanced Encryption Standard (AES)/Counter Mode CBC-MAC Protocol (CCMP), and Wired
Equivalent Privacy (WEP) with Temporal Key Integrity Protocol (TKIP) security mechanism.
For video, voice and multimedia applications the WLAN module supports 802.11e Quality
of Service (QoS). The 3-wire Bluetooth / Wi-Fi co-existence interface is also supported.
The WLAN module has a fully integrated RF to baseband transceiver that operates in both
the 2.4 GHz ISM radio band for 802.11g/b WLAN applications and 5 GHz UNII radio band
for 802.11a WLAN applications. It contains all the circuitry to support both transmit and
receive operations. The integrated LNA and AGC on the receive path is seamlessly
controlled by baseband functions. Integrated transmitters up-convert the quadrature
baseband signal and the deliver the RF signals to external power amplifiers for 2.4 GHz
and 5 GHz radio band transmission. Local o scillator frequencies are generated by a fully
integrated programmable frequency synthesizer. The loop bandwith is optimized for phase
noise and dynamic performance and quadrature signals are generated on-chip.
BT/WLAN Co-existence
Standards bodies did not fully anticipate the range of scenarios in which WLAN and
Bluetooth would compete for the same spectrum therefore IEEE 802.11 (WLAN) and
Bluetooth use the same 2.4 GHz ISM frequency band (although they use different access
mechanisms). They also did not include comprehensive, robust, and cooperative
mechanisms in their respective standards to mitigate interference. Since no mechanism
for exchanging signal status information has been built into the two standards, the task of
minimizing interference must be accomplished by other means. Co-location refers to the
situation where both Bluetooth and WLAN are in functional mode, that is, they are both
fully radio operational, performing either transmission or reception activities (or ready to
do so immediately). They also either share an antenna or each module has its own
antenna, on the same device. Because both Bluetooth and WLAN operate in the same
unlicensed ISM band (2.4GHz), steps are required to avoid disturbances and allow
coexistence. The HW solution is a single antenna controlled by an Antenna Switch with 3wired lines between WLAN Device and BT Device. The used algorithm to decision whether

Reference Noise Bypass. Bypass REFBP to AGND with a 0.22μF ceramic capacitor to reduce noise on the
LDO outputs. REFBP is internally pulled down through a 1kΩ resistor during shutdown.
DAC-Controlled Input. The output of the PA step-down converter is regulated to 2 x V
reaches 0.465 x V
, bypass mode is enabled.
IN2
200mA LDO Regulator 2 Output. Bypass LDO2 with a 1μF ceramic capacitor as close as possible to LDO2
and AGND. LDO2 is internally pulled down through a 1kΩ resistor when this regulator is disabled.
PA Step-Down Converter Enable Input. Connect to IN_ or logic-high for normal operation. Connect to GND
or logic-low for shutdown mode.
LDO2 Enable Input. Connect to IN2 or logic-high for normal operation. Connect to AGND or logic-low for
shutdown mode.
