GENERAL DESCRIPTION

The AD6526 is the second device, after the AD6522, of the

Analog Devices AD20msp430 series of SoftFone^®GSM

Baseband Processors. The AD6526 provides a competitive

solution for GSM/GPRS terminal designs. It is designed to be

fully integrated, easy to use, and compatible with GSM900,

DCS1800 and PCS1900 handsets as well as direct PC data

interface. No external SRAM is needed in most applications.

The AD6526 integrates full rate, enhanced full rate and half rate

speech codecs as well as a full range of data services including

circuit-switched 14.4 kb/s, GPRS to Class 12, and HSCSD. In

addition, it supports both A5/1 and A5/2 encryption algorithms

as well as operation in non-encrypted mode.

APPLICATIONS

The highly programmable architecture and sophisticated internal

communication channels of the AD6526 offer maximum

flexibility to system designers. It can adapt to tighter

requirements led by changes in standards and end-market feature

set requirements.

GSM850/900/DCS1800/PCS1900 Wireless Terminals
