It is designed to be fully integrated, easy to use, and patible 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 ponents 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...
