AD6528 FUNCTIONAL BLOCK DIAGRAM GENERAL DESCRIPTION The AD6528 is the third device in the Analog Devices AD20msp430 series of SoftFone® GSM Baseband Processors. The AD6528 is intended for use in feature-rich Smartphone and Wireless PDA/handheld computer applications with GSM/GPRS connectivity. It is designed to interface easily to an application processor in such systems. The AD6528 integrates full rate, enhanced full rate and half rate speech codecs as well as a full range of data services including circuit-switched 14.4kb/s, GPRS to Class 12, and HSCSD. In addition, it supports A5/1 and A5/2 encryption algorithms as well as operation in non-encrypted mode. The highly programmable architecture and sophisticated internal communication channels of the AD6528 offer maximum flexibility to system designers. It can adapt to tighter requirements led by changes in standards and multi-standard handset implementation.
