OREANDA-NEWS. February 09, 2011. Fujitsu Semiconductor America, Inc. (FSA) will showcase the latest in its portfolio of mobile device semiconductor solutions at the Mobile World Congress (MWC, http://www.mobileworldcongress.com) held in Fira de Barcelona-Recinto Montjьic on February 14-17, at the Fujitsu booth in Hall 1.0, Stand No. 1F69.

2G/3G/4G RF Transceivers

Fujitsu will present reference designs of multi-mode transceivers that eliminate 3G and LTE TX and RX inter-stage SAW filters and low-noise amplifiers. The MB86L01A 2G/3G, the MB86L10A 2G/3G/LTE-FDD, and the MB86L10A 2G/3G/LTE-TDD RF transceiver reference designs will be on display. (See related press release, http://www.fujitsu.com/us/news/pr/fma_20100601.html.)

The Fujitsu RF transceivers are compatible with a wide range of industry basebands, and feature a high-level programming model for controlling the radio using open standard digital interfaces. The compact transceiver module enables cell phone manufacturers to reduce component count, board space and bill of materials. For DigRF 4G V1.0 and 2G/3G plus simultaneous LTE-FDD and dual-band LTE-TDD support (bands 38 and 40), Fujitsu offers the MB86L12A RF transceiver.

Image Signal Processor (ISP), Milbeaut® Mobile

Also at MWC will be the latest in the Fujitsu Milbeaut Mobile family of Image Signal Processors (ISP), which feature high-definition (HD) imagery and fast processing speeds with low power consumption. The product line provides vibrant video and still images, meeting the needs of widely used digital SLRs, compact DSCs, and mobile phone cameras.

The latest member of the Fujitsu Milbeaut series, the MBG041 M-7MO, incorporates significant performance-enhancing technologies that improve image quality and performance. This ISP's dual-core processing delivers HD functionality with full 1080@30p output for optimal images. One core provides full HD video, while the second enables object tracking, face/scene/smile detection, motion-blur correction, image stabilization, and other leading-edge capabilities. The MBG041 M-7MO also incorporates enhanced Bayer filtering, which reduces noise and signal-to-noise ratios, optimizing color resolution.

"The success of the Fujitsu Milbeaut series is based on the company's long history and experience in the digital camera market," said Yoshi Masuda, senior manager of marketing, Fujitsu Semiconductor America. "With the M-7MO, Fujitsu brings superior D-SLR-level image quality and DSC functionality to mobile devices. We have a well-established roadmap for future development, and upcoming products in the series will add more powerful imaging features for full-size digital cameras and mobile devices."

Fujitsu MB39C326 Power Management IC: Industry's Leading 6MHz Buck-Boost DC/DC Converter

The new Fujitsu MB39C326 (http://www.fujitsu.com/us/news/pr/fma_20110203.html) power management IC is designed to power the radio frequency power amplifiers in mobile handsets and other mobile products that use a single-cell Li-ion battery. The converter switches at 6MHz, enabling designers to use a smaller inductor. That can reduce the board space of the power management circuits by up to 50 percent. The optimized voltage-control mechanism for full-charge and discharged-battery states automatically switches between buck operation (stepping down the voltage) and boost operation (stepping up the voltage). This prolongs battery life and efficiency, resulting in longer operation on a single charge.

"The market for mobile and smart phones, e-book readers, and other handheld mobile devices is demanding higher application performance and higher data transfer rates in the smallest form factor possible," said Akio Nezu, senior manager of marketing, Fujitsu Semiconductor America. "To meet this demand, manufacturers are aggressively trying to miniaturize components and reduce board space without impacting performance. Typically, one of the largest components is the passive inductor. Because the new Fujitsu MB39C326 buck-boost DC/DC converter operates at an industry-leading 6MHz, manufacturers can use a much smaller inductor, thereby reducing the board space requirements for the power management circuits by as much as half while also increasing battery life and efficiency."
