Fujitsu preps mobile WiMAX SoC

Sunnyvale, Calif.—Fujitsu is getting ready to sample in August its first mobile baseband SoC that is designed using 90-nm low-leakage process technology.

Fujitus is aiming the MB86K21 802.16e to be the first device its class to participate in WiMAX Forum Wave 2 certification. The MB86K21 802.16e mixed-signal SoC is well-suited for PC cards and other media-rich mobile applications.

The MB86K21 802.16e achieved an 18.6-Mbits/s transfer rate in sample installations and lab demonstrations. At that speed, the chip delivered 240-mW, according to the company. The power draw is expected to be sharply less than 500-mW, even at the theoretical highest throughput of 45-Mbits/s DL. Fujitsu's clockgating techniques and proprietary low-leakage process technology enabled the MB86K21 802.16e to yield just 10-mW in sleep mode.

The mMobile WiMAX SoC will include all features required for WiMAX Forum Wave 2 mobile device certification. It will also feature a highly integrated 512/1024 FFT OFDMA PHY with integrated MAC processors; support for 5MHz and 10MHz channel bandwidths; adaptive modulation schemes (64QAM, 16QAM and QPSK); security implementation based on AES-CCM; support for 2×2 STC/MIMO and antenna diversity; USB 2.0 and card bus/PCI host interface support; and a small footprint FBGA package.
