GENERAL DESCRIPTION
The 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 compat-
ible with a wide range of product solutions. Examples are
GSM900, DCS1800, PCS1900 handsets and PCMCIA data
cards. The AD20msp415 is the higher integrated successor of
the AD20msp410 chipset, which passed European GSM Type
Approval in June, 1996.
The chipset consists of two highly integrated, sub-micron, low
power CMOS components that perform the entire baseband
signal processing of the GSM handset. The system architecture
is designed to be easily integrated into current designs and form
the basis for next generation designs.
The chipset uses an operating supply voltage of 2.7 V to 3.3 V
which, coupled with the extensive power management features,
significantly reduces the drain on battery power and extends the
handsets talk time and standby time.
CHIPSET COMPONENTS
GSM Processor (GSMP)
The AD6422 combines application specific hardware, an em-
bedded 16-bit DSP and an embedded 16-bit microcontroller
(Hitachi H8/300H). It performs channel coding and decoding
and executes the protocol stack and user software. The DSP
implements full rate speech transcoding according to GSM
specifications, including Discontinuous Transmission (DTX)
and Comfort Noise Insertion (CNI). A high performance soft-
decision Viterbi equalizer is also implemented in software em-
bedded in the DSP. The embedded microcontroller executes
the Layer 1, 2, 3 and user MMI software. The required Layer 1
software is supplied with the chipset. To ensure minimum power
consumption, the GSMP has been designed to control all the
power-down functions of the other components in the handset.
Voiceband/Baseband Converter (VBC)
The AD6421 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 VBC contains all the auxiliary convert-
ers for burst-ramping, AFC, AGC, battery and temperature
monitoring. The chipset interfaces directly with the radio and
supplies all the synthesizer and timing control signals required
to support two synthesizers and a variety of radio architectures
including the AD6450 GSM RF-Chipset.
Software
The required Layer 1 software is supplied with the chipset. In
addition, an object code license is available for Layers 2 and 3 of
the protocol stack.
