GSM CHIPSET
GE NE RAL DE SCRIPT ION
T he Analog Devices GSM baseband processing chipset provides
a competitive solution for GSM based mobile radio systems. It
is designed to be fully integrated, easy to use, and compatible
with a wide range of product solutions. GSM phones using this
chipset and its accompanying Layer 1, 2, 3 software have passed
the European GSM full type approval process.
T he chipset consists of three highly integrated, sub-micron, low
power CMOS components that form the core baseband signal
processing of the GSM handset. T he system architecture is
designed to be easily integrated into current designs and form
the basis of next generation of designs.
T he chipset uses an operating voltage of 2.7 V to 3.6 V, which
coupled with the extensive power management features,
significantly reduces the drain on battery power and extends the
handset’s talktime and standby time.
CHIPSE T COMPONE NT S
Algorithm Signal Processor (ASP)
T he ASP is an application specific variant of the ADSP-2171
standard DSP from Analog Devices. It has been optimized to
meet the cost, size and power consumption requirements of
GSM mobile applications. All necessary memory to run the
GSM specific programs is provided on-chip and with its
FEATURES
Passed European GSM Phase I Type Approval
Complete Baseband Processing Chipset Performs:
Speech Coding/Decoding, According to GSM 06.XX
DTMF and Call Progress Tone Generation

APPLICATIONS
GSM/DCS1800 Mobile Radios and PCMCIA Cards
preprogrammed ROM, no user programming is required. T he
ASP implements full rate speech transcoding according to GSM
specifications, including Discontinuous T ransmission (DT X )
and Comfort Noise Insertion (CNI). A high performance soft-
decision Viterbi equalizer is also implemented in software,
embedded in the ROM.
Physical Layer Processor (PLP)
T he PL P combines application specific hardware and an
embedded 16-bit microcontroller (Hitachi H8/300H) to
perform channel coding and decoding and execute the protocol
stack and user software. T he embedded processor executes the
Layer 1, 2, 3 and user MMI software. T he PLP can control all
powerdown functions of the other chips and memory support
components to achieve maximum power savings.
Baseband Converter (BBC)
T he BBC performs the voiceband and baseband analog-to-
digital and digital-to-analog conversions, interfacing the digital
sections of the chipset to the microphone, loudspeaker and radio
section. In addition, the BBC contains all the auxiliary convert-
ers for burst-ramping, AFC, AGC, battery and temperature
monitoring. T he chipset interfaces directly with a variety of
industry standard radio architectures and supplies all the
synthesizer and timing control signals.
