Transceiver NPM–9

Introduction

The NPM–9 is a dual band radio transceiver unit for the E–GSM900 and

GSM1800 networks. GSM power class is 4 and GSM1800 power class is

1. It is a true 3 V transceiver, with an internal antenna and vibra.

The NPM–9 phone includes integrated FM radio. Radio is used as a nor-

mal mono receiver. FM radio is highly integrated. Only few external com-

ponents are needed. Headset is used as an antenna for radio.

The transceiver has a full graphic display and the user interface is based

on a Jack style UI with two soft keys.

An internal antenna is used, there is no connection to an external anten-

na.

The transceiver has a low leakage tolerant earpiece and an omnidirec-

tional microphone, providing an excellent audio quality. The transceiver

supports a full rate, an enhanced full rate and a half rate speech decod-

ing.

NPM–9

System Module & UI

An integrated IR link provides a connection between two NPM–9 trans-

ceivers or a transceiver and a PC (internal data), or a transceiver and a

printer.

The small SIM ( Subscriber Identity Module ) card is located under the

battery. SIM interface supports both 1.8V and 3V SIM cards.

Electrical Modules

The radio module consists of Radio Frequency (RF) and baseband (BB).

User Interface (UI) contains display, keyboard, IR link, vibra, HF/HS con-

nector and audio parts. UI is divided into radio PWB LA5 and UI PWB

LU9. FM radio is located on the main PWB.

The electrical part of the keyboard is located in separate UI PWB named

LU9. LU9 is connected to radio PWB through spring connectors.

The System blocks provide the MCU, DSP, external memory interface

and digital control functions in UPP ASIC (Universal Phone Processor).

Power supply circuitry, charging, audio processing and RF control hard-

ware are in UEM ASIC (Universal Energy Management).

The purpose of the RF block is to receive and demodulate the radio fre-

quency signal from the base station and to transmit a modulated RF sig-

nal to the base station.

Operation Modes

The transceiver has six different operation modes:

– power off mode – idle mode

– active mode – charge mode

– local mode – test mode

In the power off mode circuits are powered down and only sleep clock is

running.

In the idle mode only the circuits needed for power up are supplied.

In the active mode all the circuits are supplied with power although some

parts might be in the idle state part of the time.

The charge mode is effective in parallel with all previous modes. The

charge mode itself consists of two different states, i.e. the fast charge and

the maintenance mode.

The local and test modes are used for alignment and testing.

System Module LA5

Baseband Module

The baseband architecture supports a power saving function called ”sleep

mode”. This sleep mode shuts off the VCTCXO, which is used as system

clock source for both RF and baseband. During the sleep mode the sys-

tem runs from a 32 kHz crystal. The phone is waken up by a timer run-

ning from this 32 kHz clock supply. The sleep time is determined by net-

work parameters. Sleep mode is entered when both the MCU and the

DSP are in standby mode and the normal VCTCXO clock is switched off.

NPM–9 supports both three and two wire type of Nokia chargers. Three

wire chargers are treated like two wire ones. There is not separate PWM

output for controlling charger but it is connected to GND inside the bottom

connector. Charging is controlled by UEM ASIC (Universal Energy Man-

agement) and EM SW running in the UPP (Universal Phone Processor).

BLB–2 Li–ion battery is used as main power source for the phone.

Technical Summary

Baseband is running from power rails 2.8V analog voltage and 1.8V I/O

voltage. UPP core voltage Vcore can be lowered down to 1.0V, 1.3V and

1.5V. UEM includes 6 linear LDO (low drop–out) regulators for baseband

and 7 regulators for RF. It also includes 4 current sources for biasing pur-

poses and internal usage. UEM also includes SIM interface which has

supports both 1.8V and 3V SIM cards.

Note: 5V SIM cards are no longer supported by NPM–9 baseband.

A real time clock function is integrated into the UEM which utilizes the

same 32kHz clock supply as the sleep clock. A backup power supply is

provided for the RTC which keeps the real time clock running when the

main battery is removed. The backup power supply is a rechargeable sur-

face mounted capacitor. The backup time with the capacitor is 30 minutes

minimum.

The analog interface between the baseband and the RF section is han-

dled by a UEM ASIC. UEM provides A/D and D/A conversion of the in–

phase and quadrature receive and transmit signal paths and also A/D and

D/A conversions of received and transmitted audio signals to and from

the user interface. The UEM supplies the analog TXC and AFC signals to

RF section according to the UPP DSP digital control. Data transmission

between the UEM and the UPP is implemented using two serial busses,

DBUS for DSP and CBUS for MCU. RF ASIC, Hagar, is controlled

through UPP RFBUS serial interface. There is also separate signals for

PDM coded audio. Digital speech processing is handled by the DSP in-

side UPP ASIC. UEM is a dual voltage circuit, the digital parts are running

from the baseband supply 1.8V and the analog parts are running from the

analog supply 2.78V also VBAT is directly used by some blocks.

PAMS Technical Documentation

The baseband supports both internal and external microphone inputs and

speaker outputs. UEM also includes third microphone input which is used

in NPM–9 for FM radio. Input and output signal source selection and gain

control is done by the UEM according to control messages from the UPP.

Keypad tones, DTMF, and other audio tones are generated and encoded

by the UPP and transmitted to the UEM for decoding. A buzzer and exter-

nal vibra alert control signals are generated by the UEM with separate

PWM outputs.

NPM–9 has two external serial control interfaces: FBUS and MBUS.

These busses can be accessed only through production test pattern.

EMC shielding for baseband is implemented using a metallized plastic

frame and UI PWB ground plane. On the other side the engine is shielded

with PWB grounding. Heat generated by the circuitry will be conducted

out via the PWB ground planes.

NPM–9 radio module is implemented to 8 layer PWB. UI module is divid-

ed between main PWB LA5 and separate UI PWB LU9.
