WiMAX™ 802.16-2004 SoC
- PDF MB87M3550 FACTSHEET [71 KB]
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, MB87M3550, 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. 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 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.
