MB87M3400

MB87M3400 FACTSHEET t4 U m o .c S TM 802.16-2004 SoC WiMAX a 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 e e 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 4 t 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 an...
