GP4020GQ1Q Overview
The GP4020 is a plete digital baseband processor for a Global Positioning System (GPS) receiver. It bines the 12-channel correlator function of the GP2021 with an advanced ARM7TDMI (Thumb) microprocessor to achieve a higher level of integration, reduced system cost, reduced power consumption and added functionality. The GP4020 plements the GP2015 and GP2010 C/A code RF downconverters available from Zarlink...
