Realtek Introduces Integrated Single-Chip Ultrawideband Physical Layer Solution, Based on WiMedia Specification

2005/09/26 World's No. 1 Ethernet IC Supplier Enters Market for Emerging WiMedia Ultrawideband Common Radio Platform

HSINCHU, Taiwan and IRVINE, Calif. – September 26, 2005 – Realtek Semiconductor Corp. (TSE: 2379), one of the world's largest IC design houses, today announced it is entering the emerging Ultrawideband market with the RTL8170, a highly integrated, high performance Ultrawideband physical layer (PHY) solution based on the WiMedia Alliance PHY specification. The chip combines radio frequency (RF) and baseband (BB) components in a single CMOS chip.

The RTL8170 design includes a WiMedia MAC-PHY interface, and thus can be combined with any WiMedia medium access control (MAC) solution.  With data rates up to 480 Mbps and support for Transmit Power Control and Link Quality Indication, the RTL8170 is suitable for immediate use in combination with MAC solutions implementing Certified Wireless USB (from the USB-IF), and WiNET (IP over UWB).  The ultra-compact 7mm x 7mm size allows use in the most challenging form factors.

"Realtek's WiMedia-based PHY solution is a significant step forward for the UWB industry and the WiMedia Alliance's ecosystem,"  said Stephen Wood, president of the WiMedia Alliance. "This IC design accelerates UWB productization and further promotes the viability of the WiMedia MAC-PHY interface."

"Small form factor Ultrawideband solutions will be instrumental for embedding into space-constrained products. We see Realtek bringing its extensive mass market CMOS production experience to bear onto the UWB playing field through its Ethernet chip leadership," said Joyce Putscher, principal analyst for In-Stat. "We believe that support for both Wireless USB and IP over UWB will be important."

"Realtek is a strong believer that the WiMedia Ultrawideband common radio platform has enormous potential for end-user functionality, and represents a major market opportunity," said Ran Yan, Senior Vice President, Wireless Communications Technologies at Realtek. "In designing the RTL8170 we set our goal as an optimized ultrawideband PHY solution, maximizing feature set and performance, and minimizing form factor."

The RTL8170 comes with a compact reference design providing support from MAC-PHY interface to antenna.  The design has minimal external components and fits in a design footprint of 12mm x 12mm.

The RTL8170 will be exhibited at the Wireless USB Developers Conference held September 28-29 in Tokyo.


The Realtek RTL8170 is planned to sample to customers in Q4 2005.
