BCM2121 - GPRS/GSM Single-Chip Baseband Processor

GPRS/GSM Single-Chip Baseband Processor

The BCM2121 GSM and GPRS baseband processor offers an unprecedented level of system integration, performance and features for next generation handsets and radio cards.

The integration of the PA controller and speaker-phone/car-phone audio circuitry adds key GPRS handset features while reducing overall system cost.

The BCM2121 contains all analog and digital GSM and multislot GPRS baseband processing functions in a single chip. Interface functions and drivers are integrated to enable auxilliary components such as microphone, speaker, display, keypad, data terminal equipment and SIM to connect directly to the chip. A flexible baseband control interface supports a wide range of transceivers, including GSM850, E-GSM900, GSM1800 and GSM1900 frequency bands.
