Current Consumption Test
Step 1:
Insert Local SIM Card and use the phone with the Normal SW (SSW) and dummy battery connected
to Power Supply Channel 1 VBATT according to Picture 1.
Instrument settings: Voltage: 3.8 Volt, Limiter 3A.
Measure the current when Phone is off. Check the current consumption at Power Supply Channel 1
VBATT.
Picture 1
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:
Start the phone:
Measure the deep sleep current max 6mA typical between 0-3mA.
Make sure that the operator is running with deep sleep. (This operation can be switched off by
operator if the network is busy).
If phone using more than 6mA, then go to EMMA III and perform:
Software Update Contents Refresh (SUCR).
Step 3 with Mobile Phone Tester Instrument
Insert Test SIM Card and use the phone with the Normal SW (SSW) and dummy battery connected
to Power Supply Channel 1 VBATT according to Picture 1.
Instrument settings: Voltage: 3.8 Volt, Limiter 3A.
Use Mobile Phone Tester Instrument in signalling mode direct connected to the phone with RF
Connector or use Shield Box if not possible. Phone Display must be on during these tests to get
correct current measurements.
Perform Radio TX measurements at GSM and WCDMA Band by making the phone call from the UE
into the Mobile Phone Test Instrument (NW) and compare current consumption result with the test
limits below.
GSM 850, 900, 1800, 1900
- Transmitter current 850 MHz at Ch: 128 power level 5. Typical 350mA
- Transmitter current 900 MHz at Ch: 1 power level 5. Typical 350mA

Connection Diagram
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 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 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.
Digital Baseband Controller (CPU)
D2000 (Anja)
This component is not replaceable on SL 4 because Baseband calibration is required.
The Digital Baseband Controller is divided in two subsystems:
-Application
-Access
Access Subsystem
All modem functionality in the digital baseband controller resides in the Access
subsystem. This includes EDGE/GPRS/GSM interface, WCDMA interface, USB, 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 interface has 39 signals (including one chip
select) and supports memory sizes up to 512 Mbit. The Shared EMIF is shared between the
Access subsystem and the Application subsystem.
Application Subsystem
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 1.4 V or low impedance to ground when
powered-down. Fifty-one gains are available for BEARP and BEARN: from +15 dB down to –60
dB in
1.5 dB steps. When the BEARP and BEARN outputs are operating in differential mode, an I²C
selectable bit must invert one of the inputs.
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 and a Flash IF 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 Application EMIF
has a total of 56 signals (including a maximum of 7 chip selects if GPIO is used) and can
be set in several different modes to support different types of memory combinations.

Functional blocks of the Digital Baseband Controller
RF System Control
The access subsystem 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 3-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 GSM/GPRS/EDGE transceiver is turned on only when required.
The digital baseband controller initiates turning on of the clock. The GSM/GPRS/EDGE RF
system requires control, which is temperature dependent. The temperature within the RF
system is estimated by a voltage measurement performed by the analog baseband controller
N2000 (Vera).
Control flow of the RF system.
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, RF
inputs/outputs.

GSM/GPRS/EDGE
The GSM/GPRS/EDGE transceiver use a digital interface that is shared between receive
and transmit data. The receive interface is based on I and Q data and the transmitter
interface is based on envelope and frequency data. The quad band GSM/GPRS/EDGE
transceiver has the following general features:
The GSM/EDGE transceiver has the following features:
• Individual low-noise amplifiers for the 850, 900, 1800 and 1900 MHz frequency bands
with a common quadrature mixer
• Fully integrated VCO with dividers to generate both receive and transmit frequencies
• I and Q baseband receive channel amplifiers with on-chip antialiasing filtering
• I and Q receiver sigma-delta A to D converters
• Digital interface for the receive I and Q channel
• Multi modulus prescaler for direct VCO modulation in transmit mode
• Integrated phase detector with programmable charge pump
• Transmit output buffer with controllable output power level
• Transmit baluns integrated
• Digital interface for the transmit frequency and amplitude modulation
• 3-wire serial bus interface for control, configuration, and test
• Deep power down function
• Programmable power level to power amplifier (PA)
Frequency Generation
The 26 MHz reference signal is used as the reference for the on-chip synthesizer. To
cover the required frequency range, the integrated Voltage Controlled Oscillator (VCO)
operates at twice the frequency for band 1800/1900, and at four times the desired
frequency for band 850/900.
Transmitter
The transmitter block consists of the following sub-blocks:
A separate block is used to convert the digital bit streams from the baseband into parallel
words to be used in the DAC-s and the Sigma Delta modulator. This block also includes
programmable delays for optimizing delays between the different modulation paths. The
combined DAC and LP-filter is used to convert the digital words of the digital block into analog
signals. The second FM-path is used to add the high frequency part of the FM to the VCO. It
also includes an auto-tuning block that compensates VCO gain variations. The AM-block
converts the differential voltage from the DAC to a single-ended output that drives the PA.
The output is scaled according to the desired output power, and an offset can be added for PA
linearization. The TX-buffer is used to drive the PA with the correct power level. A divide by 2
or 4 block is used to generate the correct output frequency from the 4 GHz VCO.

Receiver
The receiver is a homodyne receiver with direct conversion of the received radio channel
to baseband I and Q channels. The analog signals are converted to digital bit streams in a
sigma delta A/D converter. The receiver block consists of a front-end with separate LNA-s for
each band and a common quadrature mixer. The front-end block is followed by a baseband
block with active anti aliasing filters that also suppress blocking signals and interferers. After
the baseband block is a fully integrated Analog to Digital Converter of sigma delta structure
with high dynamic range. The digital output signals are sent over a serial interface to the
digital base-band circuit for further processing and detection.
N1300 (RF 3100) is an integrated transceiver intended for the Universal Mobile
Telecommunication System (UMTS). The circuit is specially designed for the Frequency
Division Duplex (FDD) mode of the Wideband Code Division Multiple Access (WCDMA) that
operates in
Band I (TX Frequency Range: 1920-1980 MHz, RX Frequency Range: 2110-2170 MHz).
The baluns, loop filters and most of the passive components are included in the package.
The WCDMA transceiver has the following features:
• System in Package solution
• Single band application (UMTS band I)
• High Speed Downlink Packet Access (HSDPA) capability
• Variable duplex in band I
• Fully integrated TX baluns, loop filters and decoupling capacitors
• Low noise, wide dynamic range for zero IF RX and TX
• RX 87 dB gain control range in increments of 1 dB
• TX 80 dB gain analog control range; 1 dB minimum resolution
• RX 99 dB voltage gain
• Maximum TX output power at least +5dBm average
• Integrated RX channel filters (band I)
• RX & TX fully integrated fractional-N synthesizer with AFC control capability
• RX & TX fully integrated RF VCO with integrated supply voltage regulator
• Supply voltage from 2.6 V to 3.0 V
• 3-wire serial interface bus
• HVQFN40 package
• Lead-free
Frequency Generation
The transmitter and receiver frequency synthesizers and the VCOs are fully integrated in
the WCDMA radio circuit. The signal from the crystal oscillator is used as a reference for
the synthesizers. The two synthesizers are controlled through the serial bus from the
access subsystem of the digital baseband controller.
FUNCTIONAL OVERVIEW
Transmitter
The TX IQ modulator has differential voltage I and Q inputs. It converts input signals to
RF output frequency and is designed to achieve LO and image suppression.
The transmit output stage provides at least +5 dBm at maximum power control at the
single-ended 50 Ω output. Gain is set through the 3-wire bus.
Two 10-bit DAC-s are used to control the DC/DC converter and the PA gain.
These DAC-s are controlled through the 3-wire bus.
Receiver
The front-end receiver converts the aerial RF signal from WCDMA band I down to a Zero
Intermediate Frequency (ZIF). The first stage con sists of one single-ended low noise
amplifier (LNA) with a 16 dB gain step. This LNA is followed through an external filter by
an IQ down-mixer which consists of a mixer in parallel driven by quadrature out-of-phase
LO signals. The In phase (I) and Quadrature phase (Q) ZIF signal are then low pass
filtered to provide protection from high frequency offset interferer fed into the channel
filter. The front-end zero IF I and Q outputs are applied to the integrated low-pass channel
filter with a provision for 4 x 8 dB gain steps in front of the filter. The filter is a self-calibrated
6 pole, 2 zero filter with a cut-off frequency around 2.15 MHz and a second order group delay
compensation (2 poles, 2 zeroes). Once filtered, the zero IF I and Q signals are
further amplified with provision of 31 x 1 dB steps and DC offset compensation.
The zero IF output buffer provides close rail-to-rail output signals.

Bluetooth
The Bluetooth implementation is compliant with Bluetooth specification 2.1 + EDR.
The Bluetooth
MHz. The same band is used for both transmission and reception. This gives 79 frequency
channels.
Receiver
The first stage of the receiver is an external antenna filter, which suppresses unwanted
frequencies. The receiver is of a “near-zero” IF receiver architecture. The local oscillator is
generated by a frequency synthesizer, which allows the receiver to be set at frequencies in
intervals of 1 MHz. The synthesizer is controlled from the logic part.
The received signal is sampled in the logic for later signal processing.
Transmitter
The synthesizer generates the TX frequency which modulated by the BT baseband block. It is
then amplified. The BT system is a class 1 device with maximum of +4 dBm output power
(minimum setting is about -50 dBm).
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-todigital converters (ADCs). This advanced architecture allows the use of digital signal
processing (DSP) to perform channel selection, FM demodulation and stereo audio processing.

they 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 module N1200
(Thor). 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.

FUNCTIONAL OVERVIEW
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)
The 26.00 MHz VCXO-based MCLK is distributed as a square wave signal from the
N1200 Gimli 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 phone has power.
This clock is used to keep the Real-Time Clock (RTC) block functioning, so that the phone can
keep track of the time and date. The low frequency clock is generated in the analog baseband
controller N2000 (Vera) and distributed to the digital baseband controller D2000 (Anja), and if
necessary to external devices like Bluetooth, FM radio and A-GPS.

Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the regulator into
A1
shutdown mode. EN can be connected to IN if not used.
Fixed voltage versions only; connecting an external capacitor to this pin bypasses noise generated
A3
by the internal bandgap. This allows output noise to be reduced to very low levels.
Adjustable version only; this is the input to the control loop error amplifier, and is used to set the
A3
output voltage of the device.
Output of the regulator. A small capacitor (total typical capacitance ≥ 2.0μF ceramic) is needed from
C1
this pin to ground to assure stability.
