PAMS NSB–1 Technical Documentation System Module Functional Description The DCS 1900 engine consist of a Baseband/RF module with connections to a separate user interface module. Baseband and RF modules are interconnected with PCB wiring. The engine can be connected to accessories via the bottom system connector, the Intelligent Battery Interface (IBI) connector. The RF submodule receives and demodulates radio frequency signals from the base station and transmits modulated RF signals to the base station.

NSB–1 PAMS System Module Technical Documentation Real time clock Requirements for a real time clock implementation are a basic clock (hours and minutes), a calender and a timer with alarm and power on/off –function and miscellaneous calls. The RTC will contain only the time base and the alarm timer but all other functions (e.g. calendar) will be implemented with the MCU software. The RTC needs a power backup to keep the clock running when the phone battery is disconnected.
PAMS NSB–1 System Module Technical Documentation Power Distribution In normal operation the baseband is powered from the phone‘s battery. The battery consists of one Lithium–cell. There is also a possibility to use batteries consisting of three Nickel–cells. An external charger can be used for recharging the battery and supplying power to the phone. The charger can be either so called fast charger, which can deliver supply current up to 850 mA or a standard charger that can deliver around 300 mA.
NSB–1 PAMS System Module Technical Documentation The regulator is selectable between 3V and 5V and controlled by the SIMPwr line from MAD to CCONT. SIM card regulator is also used for after sales flash programming. COBBA analog parts are powered from a dedicated 2.8V supply VCOBBA by the CCONT. The CCONT supplies also 5V for RF. The CCONT contains a real time clock function, which is powered from a RTC backup when the main battery is disconnected. The RTC backup is rechargeable polyacene battery.
PAMS NSB–1 Technical Documentation System Module Power up The baseband is powered up by: 1. Pressing the power key, that generates a PWRONX interrupt signal from the power key to the CCONT, which starts the power up procedure. 2. Connecting a charger to the phone. The CCONT recognizes the charger from the VCHAR voltage and starts the power up procedure. Before battery voltage voltage rises over 3.0 V Charging Logic gives an initial charge (with limited current) to the battery.
NSB–1 PAMS System Module Technical Documentation Sleep Mode In the sleep mode all the regulators except the baseband VBB and the SIM card VSIM regulators are off. Sleep mode is activated by the MAD after MCU and DSP clocks have been switched off. The voltage regulators for the RF section are switched off and the VCXO power control, VCXOPwr is set low. In this state only the 32 kHz sleep clock oscillator in CCONT is running.
PAMS NSB–1 Technical Documentation System Module Power Off The baseband is powered down by: 1. Pressing the power key, that is monitored by the MAD, which starts the power down procedure. 2. If the battery voltage is dropped below the operation limit, either by not charging it or by removing the battery. 3. Letting the CCONT watchdog expire, which switches off all CCONT regulators and the phone is powered down. 4. Setting the real time clock to power off the phone by a timer.
NSB–1 PAMS System Module Technical Documentation Speech processing The speech coding functions are performed by the DSP in the MAD and the coded speech blocks are transferred to the COBBA for digital to analog conversion, down link direction. In the up link direction the PCM coded speech blocks are read from the COBBA by the DSP. There are two separate interfaces between MAD and COBBA: a parallel bus and a serial bus.
PAMS NSB–1 Technical Documentation System Module Digital control MAD The baseband functions are controlled by the MAD asic, which consists of a MCU, a system ASIC and a DSP. The DCS/PCN specific asic is named as MAD2. There are separate controller asics in TDMA and JDC named as MAD1 and MAD3. All the MAD asics contain the same core processors and similar building blocks, but differ from each other in system specific functions, pinout and package types.
NSB–1 PAMS System Module Technical Documentation The MAD operates from a 13 MHz system clock, which is generated from the 13Mhz VCXO frequency. The MAD supplies a 6,5MHz or a 13MHz internal clock for the MCU and system logic blocks and a 13MHz clock for the DSP, where it is multiplied to 52 MHz DSP clock. The system clock can be stopped for a system sleep mode by disabling the VCXO supply power from the CCONT regulator output.
PAMS NSB–1 Technical Documentation System Module SRAM Memory The work memory size can vary depending on the product variation similarly to the program memory. The work memory is a static ram of size 512kbits (64kx8). The work memory is supplied from the common baseband VBB voltage and the memory contents are lost when the baseband voltage is switched off. All retainable data is stored into the EEPROM when the phone is powered down.

PAMS NSB–1 Technical Documentation System Module Functional Description The following description of the RF is valid for both DCS1800 and DCS1900, the only difference between the two systems is: 1. antenna 2. duplexer (Z401) 3. RX and TX interstage filters (Z604 and Z503/Z505) 4. UHF VCO modules (G701) 5. matching networks (discrete components) 6. PA (N500) Even though different components are used in the two engines, the footprints of the different components are the same.
NSB–1 PAMS System Module Technical Documentation Receiver The receiver is a triple conversion receiver consisting of two ASICs; CRFU2a (N402) and PLUSSA (N401). CRFU2a contains LNA bias circuitry with an external transistor which provides step gain depending on the incoming RF level and the first and second mixers. PLUSSA contains the third mixer. All filtering is external. The received RF signal from the antenna is fed via the duplex filter (3 pole bandpass filter; Z401) to the LNA.
PAMS NSB–1 Technical Documentation System Module Transmitter Transmitter chain consists of IQ–modulator, upconversion mixer, TX filter, TX buffer and a power amplifier. The differential I and Q signals are generated by COBBA_GJ and are filtered by an external RC network (R501, R504, C525 and C526, fc=200kHz) before being fed into the IQ modulator in PLUSSA (N401). The modulator generates a TX IF of 400 MHz which is derived from the VHF synthesizer output (divide by two).
NSB–1 PAMS System Module Technical Documentation Power Detection Circuit The power detector gives an indication of output RF power by rectifying the RF voltage to a DC voltage. Ideally the output voltage of this peak envelope detector is the peak value of the RF voltage but in real world the output voltage is somewhat smaller depending on the quality of the detector diode. Due to low supply voltage used in the phone the maximum envelope voltage of the detector is limited to about 1.5V.

NSB–1 PAMS System Module Technical Documentation Frequency Synthesizers A 13 MHz VCTCXO module is used as a stable reference for both the RF and BB circuitry. Temperature variations in the VCTCXO module are controlled by an AFC voltage which is generated by a 11 bit D/A converter in COBBA_GJ. The output of the VCTCXO module feeds both the UHF PLL and the VHF PLL (both of which are located in PLUSSA) and the BB circuitry for A/D conversion.

The receiver is switched on approximately 150 s before the burst begins, DSP measures the receive signal level and adjusts the TXC–DAC (which controls Receive Controlled Gain Amplifier) or it switches on/off the LNA with the FRAC control line.

AFC The AFC is used to lock the MS clock to the frequency of the BS. An AFC voltage is generated in COBBA_GJ with an 11 bit ADC. This voltage then controls the center frequency of the 13 MHz VCTCXO module. Software Compensations Power Levels (TXC) vs.

PAMS NSB–1 System Module Technical Documentation Data Interface and Timing PLUSSA is programmed via the serial bus SLE, SDAT and SCLK. The data of SDAT is clocked by rising edge of SCLK. The data is fed MSB first and address bits before data bits. The data for the Programmable dual modulus counter is fed first and the Swallow counter last. SLE is kept low while clocking the data. During programming, the charge pump attached to programmed divider is switched to high impedance state.
