It is designed to be fully integrated, easy to use, and patible with a wide range of product solutions. GSM phones using this chipset and its acpanying Layer 1, 2, 3 software have passed the European GSM full type approval process. The chipset consists of three highly integrated, sub-micron, low power CMOS ponents that form the core baseband signal processing of the GSM handset. The system architecture is designed to be easily integrated into current designs and form the basis of next generation of designs. The 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.
