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.
