| MB87M3400 FACTSHEET t4 U om .c WiMAXTM 802.16-2004 SoC aS at w Fujitsu has developed a cost-effective, fully integrated MAC/PHY mixed signal baseband processor for Broadband Wireless Access applications. This SoC is designed to support frequencies from 2 to 11GHz in both licensed and license-exempt bands. The Fujitsu WiMAX SoC, MB87M3400, fully complies with the IEEE 802.16-2004 standard using an OFDM PHY. The SoC can operate in TDD or FDD modes and supports all the available channel bandwidths from 1.75MHz up to 20MHz bandwidths. A programmable frequency selection generates the sample clock for any desired bandwidth. When applying ee h w .D w DMA Controller Memory Interface w w w t a .D 64 QAM modulation in a 20MHz channel and using all 192 sub-carriers, the SoC's coded data rate can go up to 75 Mbps. Uplink sub-channelisation is supported as defined in the standard. The SoC's integrated ARM-926 RISC engine implements 802.16 upper layer MAC, scheduler, drivers, protocol WiMAX SoC block diagram S a e h U t4 e stacks, and user application software. A multi-channel DMA controller handles high-speed transactions among various agents on a highperformance bus. To offload processing from the upper layer MAC and enhance performance, the Fujitsu WiMAX SoC includes a separate ARC RISC/DSP engine to execute 802.16 lower layer MAC functions. The chip's multiple hardware-based encryption/ decryption engines are tightly coupled with this lower layer MAC processor and can be enabled to provide full security for the MAC privacy sub-layer. .c m o Peripherals UMAC RISC Engine Radio Control & Measurement Peripherals Interface Memory Controller Radio Control Network Interface AGC Ethernet Controller LMAC RISC/DSP Engine External Processor Interface External Processor Interface (optional) OFDM PHY & FEC Figure 1, A simplified block diagram of the Fujitsu WiMAX SoC, MB87M3400, shows the dual processors and main hardware blocks that implement a complete PHY-to-MAC wireless MAN solution w w w .D a aS t ee h 4U t om .c Radio Interface >> MB87M3400 FACTSHEET Features Full compliance with the IEEE 802.16-2004 standard Support for both subscriber stations and base stations for TDD or FDD applications High-performance modulation capabilities for complete versatility: * 256-OFDM PHY with 64 QAM, 16 QAM, QPSK, and BPSK modulation * Uplink sub-channelisation for 16 sub-channels Flexible configuration for easy system integration: * High-performance ADC and DAC for flexible baseband interfacing * Automatic frequency control (AFC) with integrated DAC * Dynamic frequency selection (DFS) with integrated ADC * Integrated ADC for transmit and receive power measurements * Rich set of integrated peripherals and RF control * Programmable automatic gain control (AGC) for supporting a broad range of RF attenuators Security implementation based on DES, AES/CCM encryption/ decryption Dual RISC processors for implementing upper and lower layer MAC Integrated memory controller and DMA controller Integrated Ethernet engine for network interface 436 BGA package Complete reference design with software and radio solution System Applications The Fujitsu WiMAX SoC suits several types of applications: BWA systems compliant with WiMAX specifications * Low-cost subscriber stations * Enterprise CPEs * Base stations 2 to 11GHz licensed and licenseexempt bands Suitable independent frequency bands at 2.5, 3.5, 3.6 or 5.8GHz Half-FDD / full-FDD or TDD applications Two Fujitsu WiMAX SoCs work together to implement full-duplex FDD applications.

The process toward certification by the WiMAX ForumTM is underway for the full-system version. This reference design includes all the software and hardware required for a cost-effective system solution. Reference Design Hardware Platforms Several hardware platforms are available with the performing chip, software, and system verification. The reference board evaluation system for subscriber stations (Figure 2) can be configured to support either TDD or HDX FDD, depending on the radio selection. The simplified base station evaluation system (Figure 3) provides an example of a full duplex FDD implementation using an external processor. The key features of the evaluation boards include: RF port interface for third-party MAC portability to different RTOSes radio Radio module Network interface On-board memory On-board control using SPI, I2C, and GPIO Debug port interfaces RS232C interface port External power supply interface Reference Design Software Platform Major features of the Fujitsu 802.16 software platform include the following: Compliance with the IEEE 802.162004 standard specification MAC security sub-layer for subscriber station authentication and data encryption Multiple service class support to differentiate service quality Dynamic service management to activate service class when needed The typical 802.16 software platform available from Fujitsu contains the following components: Host software (which runs on either the on-chip ARM9 or external processor) with the following sub-components: * Board support packages (BSPs) for popular operating systems * RTOS wrapper * Device drivers, such as Ethernet, I2C, SPI, and UART * BS or SS management and application * 802.16 upper layer MAC * 802.16 PHY service access point and lower layer MAC (PSAP/LMAC) firmware (which runs on the on-chip ARC processor) As shown in the overview of Fujitsu's software platform (Figure 4), the >> MB87M3400 FACTSHEET 802.16 upper layer MAC accesses the OFDM PHY through PSAP/LMAC firmware running on the onchip ARCtangent core. In addition to providing PHY access primitives, the PSAP/LMAC firmware includes some 802.16 lower layer MAC functionality to offload tasks from the upper layer MAC. This functionality includes encryption/decryption engines and a CRC checker/inserter. Fujitsu provides the BSP and device drivers for the supported operating systems, as well as the RTOS wrapper, thus simplifying the porting of the complete software suite to any operating system supported by Fujitsu. Fujitsu's 802.16 upper layer MAC can also be replaced with a third-party component. Fujitsu provides the full API and interface specifications to enable third parties to develop upper layer MAC components. Fujitsu also provides the PSAP/LMAC firmware for BS and SS applications. The upper layer MAC, coupled with the PSAP/LMAC firmware, make up the complete 802.16 protocol stack.
