VCO Synth. x Transceiver L N A The ML2011 GSM baseband processor offers a high level of system integration, performance, and features for next-generation handsets and radio cards. The ML2011 is a single-chip baseband device that is applicable for wireless handsets and speakerphones. The integration of the PA controller and speaker/car phone audio circuitry adds key GSM handset features while reducing overall system cost. The ML2011 contains all of the analog and digital GSM baseband processing functions on a single silicon substrate. Interface functions and drivers are integrated to enable auxiliary components, such as microphone, speaker, displays, 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. To accelerate our customer's product development cycle and to enable high-volume manufacturing, Broadcom also offers handset system solutions, including: * Complete handset and modem software, evaluation boards, reference designs, and extensive integration support * GSM Certification Forum (GCF) and interoperability testing (IOT) * Worldwide network field testing To further reduce overall component count and BOM cost, the ML2011 integrates a number of typical PCB circuits, such as a PA controller, echo cancellation chip, noise suppression chip, and hands-free answer sensing. Features such as the peripheral serial bus interface, integrated 1.8V/3V SIM, and multiplexed I&Q channels add flexibility when connecting to other onboard components. The result is a dramatic reduction in the total system IC count, footprint, cost, and power consumption. The high level of integration also simplifies the handset manufacturing process and enhances reliability because there are fewer system components. The ARM7TDMI processor runs the high-level application software, such as the SATK, WAP browser, voice recognition/recording, and user interface. The processor can interface to various polyphonic ringer chips and can control two black and white or color LCD panels for high-end handsets. The Oak DSP performs the GSM physical layer functions including voice and baseband codecs, speech coding, channel coding and interleaving, and RF interface transceiver control. To minimize power consumption, the Oak DSP uses hardware coprocessors for computationintensive processing functions. Echo cancellation and noise suppression software is also included on the DSP to target speakerphone and other noisy environments.
