Digital Audio Interface (DAI)
As required by the GSM specifications, a digital audio interface
is provided to allow certain tests of the audio section during type
approval. This interface is provided by the serial bus between
the ASP and the PLP and two additional control signals from
the PLP. A fully functional “DAI Box” needed for the FTA
process may be obtained from Analog Devices upon request.
Digital Interface to the PLP for Data Services
A conventional H8 serial port combined with a proprietary
protocol is used to interface to an external Data Terminal
Adapter.
Digital Interface from the PLP to the EEPROM
The PLP provides separate pins to interface directly to an
external EEPROM via a serial port. This EEPROM is typically
used for storage of calibration or user variable parameters like
handset identifier (IMEI), language, keypad lock and radio
calibration parameters. A typical size of the EEPROM is 2K × 8
bits, but this depends on the individual design of the handset.
GSM Baseband Processing Key Parts List
Table 1 lists the major hardware components necessary to
complete the GSM baseband processing subsystem. An example
Bill Of Material is available from Analog Devices. A full
reference design is available through Analog Devices/The
Technology Partnership.

NOTES
1These components comprise the AD20msp410 chipset.
2A size of 4 Mbits is recommended to allow storage of all GSM Layer
(1, 2, 3) programs as well as a typical user interface (MMI). Larger
memory can be used to support enhanced user interfaces.
3Can be omitted if parameters are stored in FLASH memory.
