5.2.3 Functions
Product: TDP80DN / OC2720 Processor/Audio/RF
9.2.2001
5.2.3.1 Processor I151
All the logic and audio function are implemented in the digital signal processor
(DSP).
Audio filters, copa nder/expan der, limiter , scarmbler, modem, ua rt etc. are do ne
with DSP code. DSP program is executed once for each input sample by the
operating system.
Information between the DSP code and the higher level C code is passed
trough vari ables and events
5.2.3.2 Memories
The chip contains a total of 64k x 16-bit data RAM. The RAM is powered by the
VRAM-supply, so the the RAM keeps its information when the phone is
powered off. There i s also a backup ba ttery couple d with VRAM. It i s for a short
voltage break in the main battery pack.
The program code is stored in the 16 Mbit flash memory (I201).
5.2.3.3 Sleep timer
The phone puts the central functions to sleep for a time. Although everything
seems normal to the use r, but m ost of the functions ar e closed down. Th e DSP
still has a power supply, but the processor is halted and has minimal power
consumption. Only a sleep timer and its 32 kHz crystal oscillator remain active.
The phone is ”woken up” by interrupting the sleep timer or changing the state
of the keyboard.
5.2.3.4 Power switch
When the power switch is pressed, the PWRKEY line goes low and drives the
transistor conductive. The PWRSW line goes approximately to 2.5 V caused
4Z2700GB.fm

Page 34
from voltage divider R143, R144 and depending also from the battery voltage
(VB).
The PWRSW line is coupled to DSP on/off lo gic. The DSP drives REGUEN
signal high and it drives the main regulator (I111) to operate.
The power off operation is done with the same way. The power switch is
pressed a little longer and the shutdown procedure begins. The RE GUEN
signal goes low an d powers off the phone.
5.2.3.5 Sis
SIM is performed by a BENEFON ASIC IG2048 manufactured by ATMEL.
Integrated circui t IG 20 48 is E2 logic arra y. Th is typ e o f ar ra y i n corpo ra tes bo th
electrically and programmable read only memory (EEPROM) and a gate array
for SIM funcrtion.
User specific information is stored in EEPROM which CANNOT be read from
outside the chip. Allexternal attempts to read the information clear both
EEPROM and RAM (fill with FF).

5.2.3.6 Charging control
The charging function is control led by th e softw are. The ch arge r is de tected by
PWRCHG line (High = charger detected, low = charger not detected). The type
of charger (fast or slow) is detected by the voltage at V_CHG_ADC line.
The charger switches also the power on.
There is a NTC resistor in the battery pack to measure the te mperat ure. This is
done with SBAT_ID0 line and the voltage is read by an AD convert er in DSP.
The type of battery pack in detected in a same way wi th SBA T_ ID 1 li n e with
another channel of ADC.

RF
5.3 RX SYNTHESIZER
5.3.1 General
The RX synthesizer generates an upper side injection frequency for the receiver.
The injection frequency is fed to the receive r ’s first mixer.
Operating voltage3.0 VDC
Current consumptio n14 mA
Output level to the receiver+1 dBm
Frequency range540.950...545.9 25 MHz
5.3.2 Functional Description
Product: TDP80DN / OC2720 Processor/Audio/RF
9.2.2001
The RX injection freq uency i s gene rated wit h a pha se locke d loop. The Voltage Controlled Oscillator (VCO) produces the injection frequency determined by the control
voltage. After the VCO stage comes the amplifier stage Q430. After the amplifier
stage, part of the signal is fed to the sy nthesizer circuits I400 pre-scaller Fin1. The
synthesizer circuit cont ains a pre- scaler, programmable divider , re ference freq uency
divider, and a phase detector.
The synthesizer circuit produces current pulses at output DO1 as controlled by the
phase detector. The current pulses either charge or discharge the loop filter. The
VCO control voltage is derived from the loop filter output.
The synthesizer 12.5kHz reference frequency is made by dividing the 13.00 MHz
signal from the temperature compensated oscillator (TCXO). The series-form signal
which control s the ch anne l fr equen cy come s fro m the proc essor. SDA TA, SCLK and
SLE signals are common to both TX- and RX-synthesizers. A positive pulse in the
SLE line loads the division ratio (corresponding to the frequency of the channel) fed
to the SDATA line, to the synthesizer circuit I400.

5.4 TX-SYNTHESIZER
5.4.1 General
The TX synthesizer generates the final modulated transmission frequency, which is
fed to the transmitter.
Operating voltage3.0 VDC
Current consumption<30 mA
Output level to the transmitter+6 dBm
Frequency range452.500...457.475 MHz
5.4.2 Function Description
The TX frequency is generated with a phase locked loop (PLL). The VCO produces
the injection frequency determined by the control voltage, and the VCO also has a
modulation input. After the VCO stage come two amplifier stages Q470 and Q480.
These ensure separation between the VCO and transmitter, and also boost the
injection level sufficiently. Part of the signal is fed from between the amplifier stages
to the synthesizer circuit I400 pre-scaler input Fin2. The synthesizer circuit contains
a pre-scaler, programmable divider, reference frequency divider, and a phase detector.
Product: TDP80DN / OC2720 Processor/Audio/RF
9.2.2001
The synthesizer circuit produces current pulses at output DO2 as a result of the
phase detection. The current pulses either charge or discharge the loop filter condensators. The VCO control voltage is derived from the loop filter output.
The synthesizer 12.5kHz reference frequency is made by dividing the 13.00 MHz
signal from the temperature compensated oscillator (TCXO). The series-form signal
which controls the channel frequency comes from the processor. SDATA and SCLK
signals are co mmon to both TX- and RX -synthesizers. A positive pulse in the SLEline loads the division ratio (corresponding to the TX frequency of the channel) fed to
the SDATA line, to the synthesizer circuit I400.
Modulation is fed to the TX synthesizer TX-AUDIO line. The frequency response is
corrected by the components R455 - R458, C454 and C455. Modulation sensitivity
is set by the resistor R459.

The upper side injection frequency is brought from the synthesizer through a small
resistive attenuator to the mixer. The 78.45 MHz intermediate frequency from the
mixer output is fed through the IF- filter X520 to the FM IF-circuit I550.

The second intermediate-frequency local-oscillator-frequency required by the FM IF-
circuit is generated by multiplying the 13.00 MHz reference-oscillator frequency by

The second intermediate frequency is 450 kHz. The phase-shift required by the
