GSM P r ocessor (GSMP )  
2.7 V to 3.3 V Operating Voltage  
T he 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. T he DSP  
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 em-  
bedded in the DSP. T he embedded microcontroller executes  
the Layer 1, 2, 3 and user MMI software. T he 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.

APPLICATIONS  
GSM/ DCS1800/ PCS1900 Mobile Radios  
GENERAL D ESCRIP TIO N  
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. T he AD20msp415 is the higher integrated successor of  
the AD20msp410 chipset, which passed European GSM T ype  
Approval in June, 1996.  
Voiceband/Baseband Conver ter (VBC)  
T he 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. T he 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.  
T he chipset consists of two highly integrated, sub-micron, low  
power CMOS components that perform the entire baseband  
signal processing of the GSM handset. T he system architecture  
is designed to be easily integrated into current designs and form  
the basis for next generation designs.  
Softwar e  
T he 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.  
T he 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.
