• IF THE DEVICE CAN BE INSTALLED IN A VEHICLE, CARE MUST BE TAKEN ON INSTALLATION IN VEHICLES FITTED
WITH ELECTRONIC ENGINE MANAGEMENT SYSTEMS AND ANTI-SKID BRAKING SYSTEMS. UNDER CERTAIN FAULT
CONDITIONS, EMITTED RF ENERGY CAN AFFECT THEIR OPERATION. IF NECESSARY, CONSULT THE VEHICLE DEALER/
MANUFACTURER TO DETERMINE THE IMMUNITY OF VEHICLE ELECTRONIC SYSTEMS TO RF ENERGY.
• THE PRODUCT MUST NOT BE OPERATED IN AREAS LIKELY TO CONTAIN POTENTIALLY EXPLOSIVE ATMOSPHERES,
FOR EXAMPLE, PETROL STATIONS (SERVICE STATIONS), BLASTING AREAS ETC.
• OPERATION OF ANY RADIO TRANSMITTING EQUIPMENT, INCLUDING CELLULAR TELEPHONES, MAY INTERFERE
WITH THE FUNCTIONALITY OF INADEQUATELY PROTECTED MEDICAL DEVICES. CONSULT A PHYSICIAN OR THE
MANUFACTURER OF THE MEDICAL DEVICE IF YOU HAVE ANY QUESTIONS. OTHER ELECTRONIC EQUIPMENT MAY
ALSO BE SUBJECT TO INTERFERENCE.
• BEFORE MAKING ANY TEST CONNECTIONS, MAKE SURE YOU HAVE SWITCHED OFF ALL EQUIPMENT.

Cautions
• Servicing and alignment must be undertaken by qualified personnel only.
• Ensure all work is carried out at an anti-static workstation and that an anti-static wrist strap is worn.
• Ensure solder, wire, or foreign matter does not enter the telephone as damage may result.
• Use only approved components as specified in the parts list.
• Ensure all components, modules, screws and insulators are correctly re-fitted after servicing and

Care and maintenance

Care and maintenance
This product is of superior design and craftsmanship and should be treated with care. The suggestions below
will help you to fulfil any warranty obligations and to enjoy this product for many years.
• Keep the phone and all its parts and accessories out of the reach of small children.
• Keep the phone dry. Precipitation, humidity and all types of liquids or moisture can contain minerals that
will corrode electronic circuits.
• Do not use or store the phone in dusty, dirty areas. Its moving parts can be damaged.
• Do not store the phone in hot areas. High temperatures can shorten the life of electronic devices, damage
batteries, and warp or melt certain plastics.
• Do not store the phone in cold areas. When it warms up (to its normal temperature), moisture can form
inside, which may damage electronic circuit boards.
• Do not drop, knock or shake the phone. Rough handling can break internal circuit boards.
• Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the phone.
• Do not paint the phone. Paint can clog the moving parts and prevent proper operation.
• Use only the supplied or an approved replacement antenna. Unauthorised antennas, modifications or
attachments could damage the phone and may violate regulations governing radio devices.
All of the above suggestions apply equally to the product, battery, charger or any accessory.

ESD protection

ESD protection
Nokia requires that service points have sufficient ESD protection (against static electricity) when servicing
the phone.
Any product of which the covers are removed must be handled with ESD protection. The SIM card can be
replaced without ESD protection if the product is otherwise ready for use.
To replace the covers ESD protection must be applied.
All electronic parts of the product are susceptible to ESD. Resistors, too, can be damaged by static electricity
discharge.
All ESD sensitive parts must be packed in metallized protective bags during shipping and handling outside
any ESD Protected Area (EPA).
Every repair action involving opening the product or handling the product components must be done under
ESD protection.
ESD protected spare part packages MUST NOT be opened/closed out of an ESD Protected Area.
For more information and local requirements about ESD protection and ESD Protected Area, contact your local
Nokia After Market Services representative.

Battery information

Battery information
Note: A new battery's full performance is achieved only after two or three complete charge and
discharge cycles!
The battery can be charged and discharged hundreds of times but it will eventually wear out. When the
operating time (talk-time and standby time) is noticeably shorter than normal, it is time to buy a new battery.
Use only batteries approved by the phone manufacturer and recharge the battery only with the chargers
approved by the manufacturer. Unplug the charger when not in use. Do not leave the battery connected to
a charger for longer than a week, since overcharging may shorten its lifetime. If left unused a fully charged
battery will discharge itself over time.
Temperature extremes can affect the ability of your battery to charge.
For good operation times with Ni-Cd/NiMh batteries, discharge the battery from time to time by leaving the
product switched on until it turns itself off (or by using the battery discharge facility of any approved accessory
available for the product). Do not attempt to discharge the battery by any other means.
Use the battery only for its intended purpose.
Never use any charger or battery which is damaged.
Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic object (coin, clip or
pen) causes direct connection of the + and - terminals of the battery (metal strips on the battery) for example
when you carry a spare battery in your pocket or purse. Short-circuiting the terminals may damage the battery
or the connecting object.
Leaving the battery in hot or cold places, such as in a closed car in summer or winter conditions, will reduce
the capacity and lifetime of the battery. Always try to keep the battery between 15°C and 25°C (59°F and 77°
F). A phone with a hot or cold battery may temporarily not work, even when the battery is fully charged.
Batteries' performance is particularly limited in temperatures well below freezing.
Do not dispose of batteries in a fire!
Dispose of batteries according to local regulations (e.g. recycling). Do not dispose as household waste.

Camera interface troubleshooting
Camera troubleshooting instructions
Camera troubleshooting involves debugging on two interfaces; the interface between the camera module
itself and the camera interface IC N3000, and debugging on the interface between N3000 and the baseband
IC D3100. Troubleshooting on interface between camera and N3000 is outside the scope of this specification.
In the following troubleshooting guide it is assumed that the integrity of this interface is already verified
and valid signal are present on the inputs of N3000.

RF Troubleshooting

Introduction to RF Troubleshooting
For the RF troubleshooting, generally 2 types of measurements are used: RF measurements and LF
measurements.
RF measurements are done with a spectrum analyzer (or spectrum analyzer alike?) and a high-frequency
probe, e.g. Agilent E4440A. Note that the test jig has some losses, which must be taken into consideration
when calibrating the test system.
LF (low frequency) and DC measurements should be done with a 10:1 probe and an oscilloscope. The probe
used in the following is a 10mW/10pF probe. For the other types of probes the voltages displayed may be
slightly different. Always make sure the measurement setup is calibrated when measuring RF parameters on
the antenna pad. When re-aligning the phone, the loss in the module repair jig should be included.
Most RF semiconductors are static discharge sensitive, i.e. ESD protection must be added during repair
(ground straps and ESD soldering irons). The FEM and the X-GOLD213 are also sensitive to moisture, i.e. these
parts must be pre-baked prior to soldering.
Key components are described in this document but there are also a lot of discrete components (resistors,
inductors and capacitors) where the troubleshooting is done by checking if soldering of the component is
done properly and checking if the component is missing from PWB. Capacitors can be checked for shortcircuiting and resistors for value by means of an Ohm meter. However it should be noted that in-circuit
measurements should be evaluated carefully.

Non re-workable RF Components
The non-reworkable component for the Quantum is the X-GOLD213 (D3100). All other components are reworkable.

Figure 38 D3100 is the non-reworkable components on PWB

Maintenance Overview
When the phone is received at the service centre, it is fully assembled, and it is the objective to identify the
failure area in the phone by doing fast troubleshooting and then locate the failed component(s). Since the
X-Gold213 IC is a non-replaceable component, it should be the primary task to identify whether the failure
is related to this component or not. In case of failure of the X-GOLD213 the current PCB will be replaced by a
new fully mounted PCB. The intention of the troubleshooting procedure is to find the failing component(s).
After this a re-tuning + verification of the phone is needed in order to secure passes of all RF parameters and
no more failures will be present.

Page 4 – 5

RM-704
RF Troubleshooting
Before sending the phone back to the customers a short verification step in normal mode + live network call
will be performed.
The Maintenance steps can be seen in the figure below:

Maintenance step 1
Step 1 is where the phone (MS) is fully assembled, i.e. the RF production connector cannot be used. The
purpose is to perform a quick identification of the failure mode using MS self test. The self-test feature will
not be able to detect the failed component, but in best case it can detect the failure area/functionality. Note
that the self test might not catch all failures.

Purpose of step 1:
• Fast identification of any failures when phone is assembled;
• To identify the area of the failures in order to give the operator (Service maintenance operator) further
information where to debug. (Note: Self-test will not be able to specify which component(s) is failing only
which functionality is failing.)

Maintenance step 2
Step 2 is where the phone (MS) is disassembled and the RF production connector can be used, i.e. the antenna
is not mounted. The purpose of this step is to identify the failing component(s) and replace it. In this step
the troubleshooting will be made.

Purpose of step 2:
• Identify the failure when phone is disassembled;
• Troubleshooting in order to find the specific failing component(s) and replace it/them.

Maintenance step 3
The Maintenance Step 3 is the local mode verification step. Note that this can be used for both troubleshooting
and verification.

Purpose of step 3:
• In case of the MS self-test performed in Maintenance Step 1 didn’t show any errors the verification should
identify where the error is located (on functional level);
• In case a component(s) has been replaced after troubleshooting, this step should verify that the phone
can pass all RF test after recalibration or:
a Identify if the replaced components was the component(s) causing the failure.
a Detect if other failures are present after replacing.
• To make a final calibration and verification (local mode) to make sure that the phone passes all RF limits
and requirements.

RF Troubleshooting

Maintenance step 4
In Maintenance step 4 the phone will be assembled and a short test in signalling mode in order to verify that
the assembled phone with full mechanic and antenna can pass finial UI requirements in Normal Mode, i.e.
Signalling Mode and if the phone is able to do a voice call.

Purpose of step 4:
• Finial verification step using normal mode of the full assembled phone before sending it back to the
customer;
• To verify the phone is working in live network.

Maintenance working flow
Overview
The Maintenance step 1 is the maintenance step where all self-tests are performed on the fully assembled
MS. In some case the Self-tests will detect failure i.e. tell the maintenance operator where to debug. However
in other cases the Self-test will not detect any failure however this doesn’t mean that a failure is present. In
order to locate the area of the failure it’s recommended to run verification test (Maintenance step 3) in order
to give the Maintenance operator better hint where to trouble shoot.
Below is the different working flow described depending on outcome of the different Self-tests.

Case 1: All Self Tests Passed
Below is the working flow for the case where all Self-test passed illustrated.

The phone passes all the Self-tests meaning that the Self-Test was not able to detect any failure – however
it must be assumed that a failure is present.
In order to locate the area of the failure, the RF verification in Maintenance step 3 need to be executed. The
verification step will highlight in which area the failure is present and where to start to troubleshoot.
Debugging and troubleshooting are described in the Maintenance Step 2.
After the troubleshooting i.e. finding and replacing the failing components(s) the next step is to re-tune
(calibrate) and do RF verification (Maintenance step 3). This is done in order to secure that all failures have
been removed and no further failures are present. The MS passes needs to pass all RF related test. Finally the
MS is assembled in Maintenance step 4 and verified in normal mode.

Case 2: X-Tal, Antenna detection and FEM ID Self-Test Failed
Below is the working flow illustrated for the case where all Self-test fails the X-Tal, Antenna detection or FEM
ID Self-test in the Maintenance step.

RF Troubleshooting

Debug and troubleshooting should be performed in the area of the Self-test failure i.e. if it is the X-tal selftest that fails then do the X-Tal troubleshooting etc. After the troubleshooting i.e. finding and replacing the
failing components(s) the next step is to re-tune (calibrate) and do RF verification (Maintenance step 3). This
is done in order to secure that all failures have been removed and no further failures are present. The MS
passes needs to pass all RF related test. Finally the MS is assembled in Maintenance step 4 and verified in
normal mode.

Below is the working flow described in the case where the phone fails at RF internal loop back self-test in
the Maintenance step 1.

The Internal Loop Back Self-test is a special test mode where the TX part of the X-GOLD213 is configured to
transmit on a RX frequency. This signal is weak amplified in the PA of the FEM and by the antenna switch of
the FEM directed to the RX port (not the antenna port as normal operation!) and then looped back to the RX
input of the X-GOLD213. The receiver of the X-GOLD213 is then able to measure how much of the transmitted
output power is looped back.
Since a fail in the RF loopback test can be a failure in the TX or RX (LB or HB) and the RF internal loopback selftest is not able to highlight this, it is recommended to do a verification step in the maintenance step 3 – with
the only purpose to get the info if the failure is in the TX or RX path.
After troubleshooting i.e. finding and replacing the failing components(s) the next step is to re-tune
(calibrate) and do RF verification (Maintenance step 3). This is done in order to secure that all failures have
been removed and no further failures are present. The MS passes needs to pass all RF related test. Finally the
MS is assembled in Maintenance step 4 and verified in normal mode.

Maintenance step 1—Self test
Maintenance step 1 — Self test
Run all self-tests in order to clarify if the Self-Test can detect any failures.

Maintenance step 2 –Debugging and troubleshooting
In this stage the phone is disassembled. The goal of this step is to identify the failed component(s) either by
visual inspection or by troubleshooting.

Visual inspection check flow
The purpose of the visual inspection is to try by visual to identify the area or component of root cause i.e.
locate burned components (mal colure), destroyed components, misplaced components and other visual
abnormalities.

The test signal from GSM tester must be a continuous signal, as the phone has no means of synchronizing to
a GSM burst signal in local mode. To excite the RSSI detector in the same way a modulated GSM signal does,
the test signal must either be GMSK modulated (Pseudo-random bit sequence (PRBS)) or an un-modulated
CW-signal with 67.7kHz offset from center frequency.

RF Troubleshooting
An upper part of RF Tuning Tool (RF Testing Tool too) view has controls for cables, splitters and shield boxes
defined by Nokia. A right e.g. cable must be selected because then RF Tuning has different attenuation values
for different cables, splitter and/or shield boxes. Splitter consists of splitter itself and cables to splitter (here
CA-178RS). Selections in drop down lists remains even though tool is closed and opened again so there is no
need to make selection if tuning environment remains from hardware point of view. Note that a product
specific loss in the attenuation chain comes from data package and RF Tuning summarizes all losses into one
from connection in product/module jig to instrument.

A different kind of RF tunings can be executed by RF Tuning Tool. It depends on product how many different
sequences there are. All possible tunings (sequences) are listed in Sequences drop down list (picture below,
left one). As an example (picture below, right one) product has two sequences: Cellular RF Tunings and Tests
and WLAN Tunings and Tests. Some products may have also FM TX tuning.

An actual execution for the sequence begins when the user clicks “play” button (picture below, button at far
left in three-button group). The execution can be stopped by clicking “stop” button (in the middle of threebutton group). It does not stop the execution immediately but an ongoing step in the sequence is ended
first. A “folder” button (at the right in three-button group) opens a window where log files, the execution
produces, are located.
A status of the execution is shown with the execution result “ball”. A status of the execution is indicated with
colors:
• Grey – the sequence hasn't been executed yet. The ongoing execution is shown as rotating tiny balls.
• Green –the sequence has been executed successfully.
• Yellow – the sequence execution has been stopped and all executed steps were passed successfully.
• Red – The execution was done but some step failed (e.g. limit fail), or the execution stopped due the fail
or the execution was stopped and some step in already executed steps failed.

All steps in the sequence are shown in the sequence view (below). The progress of the execution is shown
with the status indicators (balls): grey with arrow – the execution of step is ongoing, green – step passed
successfully and red – step failed.

RF Troubleshooting

The results for the tunings and/or tests can be seen when the execution is ended (stopped by user, stopped
due the error or after all steps were executed). If there are “fails” (step status is red), the results for the first
fail is shown immediately when the execution ends. If all steps were passed successfully the results are not
shown automatically but the user must click wanted step in the sequence view to see results for that step.
All results are scrollable by clicking the root of the tree view. The result view can be closed or open again by
clicking small arrow (see tiny red rectangle in the middle of the picture below) in the sequence/result view.

Some results are checked against limits. If the value is not between “Min” or “Max” it is shown with red status
indicator. It is also shown if the value is below “Min” or bigger than “Max” by highlighting the limit. The limit
fail turns also the status of step and sequence to “red”. The limits come from data package and those are
product specific.

All information shown in the result view is written to the log file during the execution.

RF Troubleshooting
The Bluetooth device UART interface allows the device to communicate with the phone baseband engine
using Bluetooth HCI (Host Control Interface) commands. When Bluetooth is switched on, the phone user
interface the BT_RESETX line is toggled to reset the Bluetooth device, and commands are sent over the UART
interface to configure the device. If UART communication fails (due to a hardware fault) it will not be possible
to switch on Bluetooth from the phone user interface.
The device has two clock signals: SYS_CLK (26.0MHz) and SLEEP_CLK (32.768kHz). The SLEEP_CLK is supplied all
the time the phone is switched on. To maximise the phone standby time, it is only necessary to provide a
SYS_CLK signal when Bluetooth activity occurs, such as sending Bluetooth data to another device, or checking
periodically if there are any other Bluetooth devices attempting to communicate with it. At other times when
the Bluetooth device is in standby mode it is only necessary to provide a SLEEP_CLK signal. The Bluetooth ASIC
is powered directly from the phone battery voltage line (VBAT). An internal regulator is enabled when
Bluetooth is switched on.
Bluetooth audio signals are sent to and from the device using a PCM interface. The Bluetooth RF signal is
routed via a buried track to the Bluetooth antenna on the side of the PWB. An RF filter is needed between
the Bluetooth antenna and Bluetooth ASIC to prevent interference to and from the cellular phone antenna.

Display
Quantum includes a 128x160, 16bit color display. The display interface has two supply voltages: 2.8V for LCD
controller and 1.8V for LCD controller I/O. The display interface is driven by the DIF (Display Interface) of the
X-GOLD213. For more details on the DIF please consult the X-GOLD213 spec.

Camera
The Camera is interfaces to the XGold213 trough a de-serializer chip, which converts from the CCP2 serial
data/clock from the camera to the 8 bit parallel interface on the XG213.

MMC/SD-card
The MMCI interface of XGold213 is used for external data storage on a SD card. The interface supports up to
52MHz clock rate, giving a peak data bandwidth of 200Mb/s.

Backlight
The LCD backlight is designed around an integrated step-up converter in X-GOLD213, which enables high
voltage generation for the serially connected LED’s in the LCD.
The current trough the LCD backlight LED’s is sensed by a resistor and can be controlled by an XGOLD213
register.

System Module
Optionally a separate keyboard backlight can be driven by a constant current sink supplied from VBAT and is
controlled from a GPIO. The keyboard backlight supports white LED with low Vf.

Keyboard
The current CHWP is designed with a 5*5 matrix keyboard i.e. up to 25 keys plus the ON key, XG213 can
support up to 6*5 which means that up to 30 keys* plus the ON key can be detected. ESD protection is optional
by providing PWB footprints for tranzorbers. If needed, these tranzorbers can be mounted. The tranzorber
footprints are physically located in a way which enables the use of the Nokia ASIP for keyboard protection,
with only minor PWB layout changes.
Note: Usage of the pin for the 6’th row is dependent on the port allocation.

Audio
The microphone, earpiece, speaker and headset are driven directly from the X-GOLD213. To obtain a sufficient
Sound Pressure Level from the speaker, a build-in class-D amplifier is used. The design supports both separate
transducer implementations as well as combined earpiece and speaker outputs, including support for 3-in-1
devices with integrated vibrator functionality.
The Engine supports two analog microphone inputs and optionally dual digital microphone inputs as well.

Vibrator
The vibrator function is supported using the VIB driver in the X-GOLD213. This driver features a VBAT supplied
push-pull output stage which is intended for driving a vibra motor. The engine also supports vibrating using
the 3-in-1 multi-actuator device, please refer to 3.3.6.

Accessory support
The accessory connector is the Nokia AV connector. The ECI function is not supported. USB data
communication is supported, but USB OTG is not supported. Also Janette headset and video cable are not
supported.

System Module
• Drive vibrator.
• Support Bluetooth and FM module through UART and I2S ports.

System power up
The system power up sequence can be seen in the following figure.
The Power-on reset (POR) circuit and the LPBG are directly connected to the battery, If the battery voltage
exceeds the POR threshold (2.5V), the POR is released, the LRTC and LPMU voltage are switched on and the
internal PMU oscillator is started.
The power up sequence can be initiated by any of the following ways if there is a battery of a valid voltage
of above SYSONLEV (3.2V):
• First connect of VBAT with valid voltage has been detected
• Input “On” pin pressed ( goes from low to high)
• Input RTCOUT caused by programmed alarm in RTC block
• A valid charger detected and the battery is charged above the SYSONPRE voltage level
• A USB cable has been connected (external circuit)
The first startup of the PMU is based on local 50 kHz PMU oscillator. This eliminates delays caused by slow
startup time of the 32 kHz RTC oscillator. The SW can later change the input for the PMU clock to the 32 kHz
oscillator and switch off the PMU oscillator to save power. The PMU power up sequence is shown in the figure
below:

Figure 52 Power up timing and system sleep

Where the system after VBAT is applied goes first into the system OFF state. Connection of a valid battery
voltage (VBAT > 3.2V) will initiate a system startup, other valid system startup causes are pressing the ON
key, connection of a USB cable or charger, or a RTC alarm event.
When the system is in OFF state, only VRTC and VPMU are activated, with the common reference generated
by the low power band-gap reference LPBG. Upon detection of a valid turn-on event, first the high precision
band-gap reference is turned on, then the 1.8V step-down converter SD1 and the VCORE LDO are turned on
controlled by the PMU HW state-machine. The control signal RF_SYSCLK_EN is asserted to power up the DCXO
regulator in the RF macro, and after the DCXO has stabilized, the 26MHz system clock is available. The RESETX
signal is released 16ms after assertion of RF_SYSCLK_EN.
When RESETX is released, activation and control of the remaining supplies is done by SW, hence no exact
timing figures can be given here. The SW will, as one of the first actions, enable the 32 kHz oscillator and
enable the digital SLEEPCLK output, and turn on the 2.85V VAUX regulator. Control of remaining supplies (VSIM,
VMMC, VUSB, RF supplies) is handled by the respective SW drivers.

The following figure provides a more SW oriented view of the system startup or boot process. The upper part
contains the HW controlled part of the startup sequence up until release of the RESETX reset signal. After this
the boot ROM starts executing, validating the flash PSI and detecting if a flashing process is requested over
the USB interface.
Depending if a flashing process is requested or not, the boot ROM code will either exit and the flash PSI
followed by normal system code will be executed in the case of a normal startup, or the flashing process will
be initiated by downloading and executing the RAM PSI from the flashing host.

Modes of operation
Figure 2 also shows the sleep mode transitions in a PMU context. When the system enters sleep mode, the
state of a number of the power management functions will be changed controlled by the RF_SYSCLK_EN signal
to reduce current consumption. Most devices can be put into off or standby mode such as the LDOs and DC/
DC converter, to minimize quiescent current. The DC/DC converter can be programmable into its low power
mode (PFM) and VCORE changes the output voltage to a lower value. The HPBG (HIGH PRECISION BANDGAB) is
deactivated and the DCXO in RF is switched off.
Exit from sleep mode is initiated by expiration of the sleep timer or detection of a HW interrupt.

Power distribution
The X-GOLD213 contains regulators for all power supplies needed in various parts of the chip. The regulators
are LDO type linear regulators except the 1.8V step down DCDC converter. The LDO’s are powered from either
battery or the step down converter. The following figure depicts the complete power management unit with
the regulators. Supply inputs VRF1 and VDD1V8 are connected to the output of the step down converter SD1,
thus increasing the efficiency of the downstream supplies for the RF, the digital core and the analog part by
the conversion factor of the step down. The remaining regulators are supplied directly from the battery
voltage.

System Module
The above figure shows the VPMU, VMMC, VSIM, VRTC, VUSB and VAUX LDO outputs of X-Gold213 together with
the output decoupling capacitors. VANA is implemented with a cap-less LDO, hence this supply is not available
on any X-Gold213 balls. Main part of the system is powered from a 1.8V supply rail. This voltage is generated
by the integrated step down converter (SD1) which needs only an inductor L2204 plus input and output
decoupling capacitors C2207 and C2206.

Figure 55 Power supply distribution

The above figure shows the power supply distribution of Quantum for the supplies which are used outside
the X-Gold213. Regulators in the X-GOLD213 convert the battery voltage VBAT to regulated supplies for the
various peripherals. The SD-card features dedicated regulator. A shared supply concept is used for other
peripherals. This means in general that there is no power on/off control implemented for the shared supplies,
these regulators will be enabled always when the system is on.

Clocking concept

Figure 56 XG213 clock generation and distribution

The above figure provides an overview of the clock generation and distribution inside XGold213. The 26MHz
DCXO is located in the RF macro and supplies the XGold213 with the main clock input. This clock is optionally
available also on the FSYS1 and FSYS2 outputs as sine wave outputs. In Quantum only FSYS1 is used for the
BTFM module. The 26MHz signal from the DCXO is buffered and made available for the digital part of the
XGold213 through the CGU (Clock Generation Unit). Here a PLL and phase shifters generate higher frequency
clock signals which are then fed to the various on-chip HW blocks through a set of multiplexers and dividers,
allowing for a very flexible clocking scheme. The clocks are also available a digital clock outputs on the CLKOUT
[0:2] balls. Currently in Quantum CLKOUT0 is assigned for the 32 kHz SLEEEPCLK, and CLKOUT2 is assigned for
the camera clock, and CLKOUT1 is not used.
The low power 32 kHz oscillator is enabled under SW control and is available during system sleep for all HW
blocks to allow operation is sleep mode with very low power consumption.

Audio concept
The VMIC supply is intended for the biasing of the internal microphone and the VUMIC for the biasing of the
headset microphone. There are 4 voltage settings for VMIC and VUMIC ranging between 1.8V and 2.2V. The
default setting for both supplies in XMM2130 reference design is 2.2V. VUMIC has an ultra-low-power mode
which is used only when a headset is connected and the mobile station is in sleep mode. To be able to detect
a key press on the hook key, the bias supply needs to be enabled. VUMIC is switched to the standard mode
during audio operation for optimal noise performance.

RM-704
System Module
The internal microphone inputs via filtering components to the MICP1 and MICN1 inputs of XGold213. DC
blocking capacitors C2102 are inserted to center the audio input around the internal bias level. The
microphone circuit is configured in pseudo-differential mode. VMIC is used for the bias. A low-pass filter
comprising R2100 and C2101 is used to remove any potential noise picked-up by VMIC. The external
microphone for the headset is connected via filtering components to the second differential microphone
input MICP2 and MICN2, and is designed pseudo-differentially for better noise immunity. DC blocking
capacitors C2107 are used for the biasing. A low-pass filter comprising R2105 and C2105 removes any
potential noise picked-up by VUMIC. As a relatively high gain is applied to the uplink signal in the X-GOLD213,
a noise suppression filter is inserted. Microphone signals are connected differentially between X-GOLD213
and filter circuitry in order to achieve a good common mode noise rejection.
Downlink audio can be routed to the headset output drivers, earpiece driver or the class-D speaker amplifier.

Figure 57 X-Gold213 audio output selection

The X-Gold213 features stereo headset drivers, each driving a 16ohm load with an output power up to
30mWrms. With different register settings, either a stereo or mono configuration can be selected. In the
mono configuration, only the R-DAC is used, with the signals still routed through to both HSR and HSL. The
X-Gold213 also contains a charge pump which is used to supply the internal headset amplifier in bipolar
mode (generates -1.3V). When using this mode, the external DC blocking capacitor can be removed. For
Quantum only bipolar mode will be supported. For this application an external capacitor C3016 is connected
to the CP1 / CP2 balls. The charge pump is driven by a 13 MHz clock.
The EP buffer (EPP and EPN) is specified to have a max power output of 100mWrms, at a load16ohms.

RM-704
System Module
Quantum supports dual or single speaker configuration. Single speaker configuration is used when having
either just a single speaker for both IHF and normal handset operation, or when using a multi-actuator or 3in-1-device with integrated vibrator functionality. For single speaker configurations 3.9 Ohm serial resistors
must be inserted in the earpiece driver outputs as indicated in the above figure to isolate the driver from
the low speaker impedance.
The X-GOLD213 has an integrated Class D power amplifier (LSP/LSN) that can drive an 8ohm load at the
maximum rating of 700 mW rms (at VBATmax). The Class D amplifier is supplied directly by the phone battery
and therefore the driving capability depends on the battery voltage.
The default switching frequency of the amplifier is initially set to approximately 600kHz, but may be varied
between 400kHz to 800kHz in the case of harmonic interference to the GSM RF frequencies or FM radio receive
channel. External ferrite beads L3100 and L3000 have been added on the amplifier outputs to minimize
interference.

Baseband electrical interfaces: Battery
X2080 is battery connector, battery supply voltage range is 3.2V to 4.2V. The middle pin of the connector is
for battery ID, the BSI resistor value should be 68K (default value, normal mode without charging) or 3.3K
(test mode), the nominal resistance of actual NTC resistor is 47K at room temperature.

Baseband electrical interfaces: Charger
Charge voltage is detected by an external voltage divider. The voltage (VCHG) is measured by a 10-bit PMU
ADC with a dynamic range from 0 to 1.2V. The maximum ADC voltage corresponds to 32.4V with the current
external divider ratio hence the resolution is 31.6mV/LSB.
In order to validate the charge voltage, an upper and a lower limit are programmed in the PMU charger
control registers. These registers can be programmed by SW during run-time. During HW controlled
precharge, the reset values are set to allow a nominal charge voltage range of 4.1 to 10.0V. Upon charger
detection, the charger voltage is compared against the charge voltage limit register values, and charging is
only done if the voltage is within the allowed window. When SW is running the charger detection window
can be re-programmed to comply with product specifications. In Quantum the charge detection window will
be set to comply with Nokia 2mm charging specification for normal and special chargers.

Baseband electrical interfaces: Display(s)
The X-Gold213 DIF module provides the flexibility for the main processor to communicate with an external
display of various possible type of interface.
In order to establish communication to different displays the DIF supports the low-level part of the protocol
which can be configured via several registers. The low-level part covers the number of pins, their functionality
and polarity. It also covers the timing parameters for the serial or parallel access of reading from or writing
to the display.
The DIF module provides the following main features:
• Serial interface (supports up to 26 MHz clock rate)
• 8/9 bits high speed parallel interface with programmable timing requirements
• Multiple input formats possible: RGB up to 32 bit/pixel
• Hardware accelerator for physical protocol (pixel-bit conversion) allows to generate all common output
formats for various colour depths, for example (R,G,B) =(3,3,2), (4,4,4), (5,6,5), (6,6,6), (8,8,8).
• Provision of synchronization signals to eliminate tearing effects (only in combination with the parallel
display interface)

Figure 61 Serial display connection

Quantum supports both serial and parallel displays, as well as combinations of the two. The figure below
shows how the display interface signals in XGOLD213 are mapped to the parallel and serial interfaces of the
display(s). The Rx resistor is only needed when using dual displays, where one has serial and the other a
parallel interface. The resistor will limit the maximum achievable bit rate in the receiving direction (LCD read)
to app 3.25 Mb/s due to the RC filter constant created by Rx and the DIF_D1 input capacitance (Assuming Rx
= 2.2 kOhm and Cin = 10 pF). In single serial display applications Rx should be shorted (MESSI_CMT0 and
MESSI_CMT1 shorted).
In a dual display configuration, a GPIO must provide the chip select output for the serial connected display.

Baseband electrical interfaces: SIM
The Universal Subscriber Identity Module or USIM card is the logical extension of the SIM card into the 3G
environment, as an evolution of the SIM card. It can be used for support of GSM Phase 2 and 3G modes.
The X-GOLD213 USIM interface is compatible with ISO 7816-3 IC card standard, required by GSM11.12 (3.0V
and GSM 11.18 (1.8V) standards. It supports both 1.8V and 3.0V SIM Cards with T=0 and T=1 protocols
supported by hardware. For 3V SIM cards, the nominal supply voltage is 2.85V. The SIM card is provided with
a 3.25MHz clock and can be configured into low power modes. All SIM related clock signals are controlled by
the SIM_CTRL register in X-Gold213.

RM-704
System Module
For ESD protection of the SIM interface signals, an integrated ESD/EMI suppression component is used. A 100nF
capacitor is located very close to the SIM card connector for supply decoupling. The Design of the X-Gold213
IO’s ensures that all SIM signals are actively driven low as long as a valid battery voltage is present, even in
off mode, to comply with ISO7816-3 specifications.

Baseband electrical interface: Dual SIM
Dual support in Quantum is implemented using a dedicated dual SIM interface IC, LFH1001 from Infineon.
The LFH1001 is a dual SIM card interface IC for use in mobile stations. It has two LDOs to provide power
conversion for 1.8V and 3.0V and three level shifters per SIM card for signal level translation.
The LFH1001 interfaces between a baseband IC and two SIM cards. The LFH1001 multiplexes the signal paths
of the two SIM cards so that one will be connected to the SIM interface in the baseband IC, while the other
is left in clock stop mode. This allows both SIM cards to be powered and provides a flexible and efficient way
of switching between the two cards without having to execute repeated de-activation and activation
sequences in order to access the two cards.

Figure 65 Dual SIM using LFH1001

The LFH1001 has an integrated detection of SIM card presence based on two application concepts:
• Battery detection in case one or both SIM cards are located behind the battery
• Contact detection in an external card reader, in case one SIM is located in a directly user accessible slot
The LFH1001 contains logic for detecting the state of the SIM cards and performing automatic shutdown of
the SIM interface signals in case removal of the card is detected.

Baseband electrical interfaces: Keyboard
The key interface supports a 5 x 5 matrix. There are two different modes of operation: standby mode and
active scanning mode.
In standby mode all scan output rows KEYOUT[0:#] are set to low. The scan input columns lines KEYIN[0:#]
are pulled high by internal pull-up resistors. In case of a key press, the corresponding KEYIN will be pulled
low. The logic states of all the input lines are AND’ed internally in the GOLD213 to generate an interrupt
request to wake up the CPU if any key is activated during standby. In case of interrupt, the CPU will read the
corresponding row and initiate an active key scan to identify the correct column. The key interface will also
allow detection of two simultaneously pressed keys.
The PWRON key is for power on function, it is pull up by VRTC.

Baseband electrical interfaces: Camera
The X-Gold213 CIF is a high performance camera interface block that implements the complete video and
still picture input interface solution for mobile phone applications. It supports a maximum input frame
resolutions of up to 3MPixels (2048x1536 pixels).
Since X-Gold213 does not support a serial camera interface, an interface, or de-serializer, IC is used. This IC
converts the CCP-2 compatible serial camera data to an 8-bit parallel format compatible with the XGold213
camera interface.

RF System Module
Overview
This Chapter contains a brief introduction to the design of the RF part for the Quantum engine block in order
to give the maintenance operator a good knowledge of the RF HW for making debugging and troubleshooting
easier.
The assumption is that the service centre is equipped according to the Nokia’s Level 3 as described in
“Recommended service equipment, for authorized Nokia service suppliers” Version 30, 01 Nov. 2009 by
Nokia.

RF general description
The RF part of the Quantum engine is a 2G block using the Infineon X-GOLD213 IC RF sub-system as the RF
transceiver module, which supports dual-band GSM voice and data applications (GPRS class 10 with the
feature of RX EGPRS capability). It also supports 2 different Front End Modules, FEM, (Renesas EU and Skyworks
EU) includes both dual-band power amplifiers and antenna switch for RX/TX path switching functionalities.
The 26MHz reference clock is generated by a build-in digitally adjustable oscillator with one off-chip crystal.
Furthermore the engine supports FM radio functionality with an on-chip FM radio block. The external circuitry
needed for the FM radio is the LNA and the antenna. BT is also supported with an external BT chipset.

Frequency plan
Quantum is a dual band engine, which supports either EU version or US version frequency bands. The
frequency plan and power class are shown in the following table.

TX path overview
The TX digital architecture in the X-GOLD213 IC is based on a fractional-N sigma-delta synthesizer to generate
the two outputs at the TX1 port and TX2 port; LB and HB respectively. At The TX outputs, the AC coupled
Capacitors are removing the DC from the X-GOLD213 IC, the RF signal is then harmonic filtered by a H4 filter
(4th Harmonic Notch Filter) for LB and a H2 filter (2nd Harmonic Notch filter) for HB (both filter are series
resonance filter to GND), and attenuated by a 2dB attenuator before the FEM (PA+ antenna switch). The input
signal to the FEM is a GMSK RF modulated carrier signal in the range of -3dBm to +3dBm. The PA amplifies
the signal to its wanted output power level (PCL of the GSM specification) determined by the amplitude level
of the Vramp signal. The RF output signal from the FEM is delivered to the RF connector (RF production/debug
connector) if a RF cable is present or to the Antenna Pad in case of no RF cable connected. A detailed description
of the TX path in the RF part of the Quantum engine can be found in Appendix B.

RX path overview
The RX signal is input from the Antenna or from the RF connector if the RF cable is attached to the production
RF connector. The RF signal is then input to the antenna switch of the FEM, where it is switched to either the
LB path or the HB path. This is controlled by the settings of FE1/VC1 (TX-RX Switch), PABS/VC2 (Band Select),
and FE2/VC3 (Antenna Switch configuration); see the FEM logic table in Table 7. The antenna input signal is
then band-pass filtered in the SAW filter module with the RX in-band frequencies as specified in Table 1. After
BP filtering the RF signal is matched to the impedance of the X-GOLD213 IC differential inputs for optimum
receiver sensitivity performance. In the X-GOLD213 IC the RX input signals are amplified by a Low Noise
Amplifier (LNA) and down converted to Low IF and again amplified before demodulated and signal processed.
A detailed description of the RX path in the RF part of the Quantum engine can be found in Appendix A.

X-TAL/DCXO
The X-Tal and DCXO is the 26MHz Reference Clock used by the entire platform as an accurate clock. The clock
frequency can be controlled and adjusted by the embedded capacitor bank of the DCXO (Integrated in the XGOLD213). During synchronization to base-station or base-station emulator (Normal mode/signalling mode)
the accuracy of the clock should be max 0.1ppm, however in normal mode the accuracy can be ±60ppm
depending on the setting of the AFC DAC value.

Antenna detection
The antenna detection circuit is applied to determine if the antenna is mechanically mounted or not. The
antenna circuitry consist by a current sourced ADC from the X-Gold, that’s are sourcing the resistors R7454
and R7460 to the antenna pad E7454. The antenna has an 0 impedance @ DC to GND if mounted correctly.
The ADC (embedded in the X-GOLD213) measured the voltage and use this to evaluate if the antenna is
mounted or not, and if the antenna connection to the pad E7454/E7453 is okay or not. The detailed circuit
is shown in the figure below.

FEM ID/PA ID
The FEM ID (PA ID) is used for FEM identification depending on the different release, see Table 2 . For more
