SEMC Troubleshooting Manual
C903

Current Consumption Test

Perform the Ohm measurements by using the DMM instrument (Fluke).
Note! The Battery must be removed from the Phone during this test.
Note! Connect the Black probe to the X2405_PIN 9 (GND).

Step 1:
Insert a Local SIM Card and use the phone with the Signalling SW (SSW).
Use Dummy Battery connected to Power Supply Channel 1 (VBATT).
Instrument settings: Voltage: 3.8 Volt, Limiter 3A.

TROUBLESHOOTING

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.
Step 2:
Turn the Phone On:
Measure the deep sleep current max 6mA typical between 0-3mA. Make sure that the
operator is running with deep sleep mode.
Note! This operation can be switched off by operator if network is busy or heavily-loaded.
If phone using more than 6mA, then go to EMMA and run Software Update Contents Refresh
(SUCR SW).

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 charging
PWM controlled charging
Over-voltage and over current detection
Watchdog termination
DCIO assertion/removal detection
Voltage and current measure functions
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 when 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.
FUNCTIONAL OVERVIEW

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 charging
• Constant current charging
• Watchdog termination
• Trickle LED indication
• VBUS assertion/removal detection

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).

SIM Interface

The SIM interface supplies level is shifting between the digital baseband controller and the
SIM/USIM card. Moreover, hard-wired SIM deactivation functionality manages removal of
a SIM card that has not been powered down.

The Digital Baseband Controller is divided in two subsystems: Access and Application

Access Subsystem

All modem functionality in the digital baseband controller resides 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 Access 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 for distributing 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:

FUNCTIONAL OVERVIEW

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.

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.

FUNCTIONAL OVERVIEW

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, which is a set of control buses connecting the different 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

FUNCTIONAL OVERVIEW

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

Frequency Generation

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.

EDGE/GPRS/GSM Transmitter Part

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 mode, the EDGE/GSM/GPRS signal from the antenna passes through the switch
to one of the four receive SAW filters. The SAW filter provides receive band selectivity. 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).

Transceiver

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.

FUNCTIONAL OVERVIEW

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 signal 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.

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.

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.

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.

RF System Control
Ericsson RF 3300 Block Diagram:

The access side of the digital baseband controller controls the overall radio system.
In both EDGE/GSM/GPRS and WCDMA air interface mode, the digital baseband controller
controls the radio system through a three-wire serial bus. The digital baseband controller
also manages PA band control and the antenna switch mechanism in the front end module.
The 26 MHz VCXO clock residing in the transceiver is turned on only when required and
initiated by the digital baseband controller.

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 BluetoothTM transceiver has frequency channels with 1 MHz separation from 2402 to
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 input 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 mixer output signals are band pass filtered 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/4DQPSK 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 synthesizer technology including a completely integrated 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
bottom of the phone.
System connector pin input/output 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.

Master Clock
(26 MHz)

SEMC Troubleshooting Manual
C903

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.

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:

FUNCTIONAL OVERVIEW

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.

Technical Description

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.

The column “Type” describes the pin directions:
FM_VA

– O for Output
– I/O for Input/Output
– O/t for tri-state output
For the output pin the default drive capability is 2 mA, except for pin K3 (BT_GPIO_11) and pin L3
(BT_GPIO_8) where it is 8 mA such that when used for Class 1, these 2 pins can be used for a switch
control in a cheaper way.
