Realtek Announces Single-Chip
CMOS Ultra-Wideband Solution Supporting Certified Wireless USB Device Controller and WiMedia Logical Link Control Protocol
May 22, 2007
HSINCHU, Taiwan and IRVINE, Calif., May 22 /PRNewswire/ -- Realtek Semiconductor Corp. (Taiwan
Stock Exchange: 2379.TW), one of the world's largest IC design houses and a market leader in Ultra-Wideband (UWB) technology,
today announced its RTU7105, a highly-integrated, single-chip, all-CMOS solution supporting Certified Wireless USB Device
Controller and WiMedia Logical Link Control Protocol functionality. The chip integrates Protocol Adaptation Layers, a Media
Access Controller (MAC), a baseband processor, RF transceivers, and USB2.0 and SDIO interfaces. Combining advanced functionality
with an ultra-compact form factor, the RTU7105 is suitable for all Wireless USB Device applications, particularly mobile and
portable applications where footprint size and power consumption are critical. The RTU7105 single-chip solution offers dramatically
lower cost, space, and power consumption compared with the multi-chip solutions prevalent in the industry.
The
RTU7105 provides a full array of Certified Wireless USB Device functions, including all transfer types (control, bulk, interrupt,
and isochronous), cable and numeric association models, plus a multi-host capability to maintain connection-contexts with
up to 16 wireless hosts. With USB2.0 and SDIO 1.2 interfaces, the RTU7105 can function as a Device Wire Adapter, or as a Native
Wireless USB Device offering significantly higher system throughput. In addition, the chip's innovative CrossBridge(TM)
technology provides an easy migration path to Certified Wireless USB by extending the wired USB2.0 functionality to both wired
and wireless USB.
The Media Access Controller is based on WiMedia MAC 1.0 and includes self- beaconing support
for Certified Wireless USB. As opposed to devices that implement only directed beaconing, which are limited to Wireless USB
functions, WiMedia MAC 1.0 support enables multi-protocol functionality. The RTU7105 supports the most recent version of the
WiMedia LLC Protocol (formerly known as WiNet), a protocol that enables IP-over-UWB, offering a flexible, peer-to-peer, high-throughput
mode.
In an industry first, the RTU7105 integrated radio provides dual-band capabilities, with support for both
WiMedia Band Group 1 (3.168~4.752 GHz) and Band Group 3 (6.336~7.920 GHz). In addition to expanding overall capacity by increasing
the available channels, dual-band capability provides greatly increased flexibility to tailor products for specific applications
and regulatory regions, and is of particular importance for cell phone applications. The RTU7105 complies with the latest
WiMedia PHY 1.1 specification, supporting data rates of 53.3Mbps to 480Mbps within Band Groups 1 and 3, and also implements
all mandatory portions of the forthcoming WiMedia PHY 1.2 specification, including three new frequency hopping modes in each
Band Group for additional spectrum flexibility. It includes state-of-the-art spectral notching capabilities to accommodate
evolving regulatory requirements.
The RTU7105 comes in an ultra-compact 9mm x 9mm Quad Flat No-Lead (QFN) plastic
package, and will also be made available in a smaller Chip Scale Package (CSP) form.
"Certified Wireless USB's
merging of the proven USB ecosystem with innovative ultra-wideband technology promises to expand the reach of wireless into
a vast array of consumer electronics devices, PC peripherals, and handsets," said Alex Chiu, President of Realtek Semiconductor
Corp. "With the RTU7105's combination of full functionality with high levels of integration, Realtek seeks to drive
rapid market adoption and proliferation of this technology."
"All UWB vendors will eventually have to
move to single-chip integration, which will be essential for competitiveness, particularly for the CWUSB Device market,"
said Brian O'Rourke, senior analyst at In-Stat. "The full-featured and early single-chip RTU7105 places Realtek in
a very strong competitive position."
The RTU7105 will be demonstrated at the Realtek booth, located in South
Lounge (T3F1) at Computex, Taipei, from June 5-9.
