Infineon Strengthens Leadership in MDU/MTU Market with Ethernet over VDSL Technology Patent Award

Jan 8, 2001 | Market News

Munich, Germany - January 8, 2001 – Infineon Technologies (FSE/NYSE: IFX), one of the world’s leading providers of Communications Integrated Circuits and a pioneer in the field of VDSL, today announced that the company, together with 3COM, has been awarded a patent for Ethernet Transport Facility over DSL technology. The technology, trademarked by Infineon as 10BaseS™, utilizes VDSL modem technology to provide the highest performance copper access technology currently available for the explosive MDU/MTU market.

Originally, VDSL technology was designed to provide the telephone companies with a competitive solution in their ongoing challenge with the cable companies to deliver true broadband services over existing copper infrastructure. Merrill Lynch cited in its October 2000 report forecasts that the market for semiconductors used in DSL equipment will grow by 79% through 2004 while the market for semiconductors used in cable modems will grow by only 29% through 2004. The newly issued 10BaseS patent covers the transmission of Ethernet, the most common LAN protocol over VDSL and the highest performance DSL technology currently available. 10BaseS co-exists with xDSL, ISDN and Digital PBX systems, allowing system vendors to offer standard, full duplex, 10 Mbits/s Ethernet data transfer in addition to traditional telephone services over existing copper infrastructure.

“10BaseS is best suited for the Multiple Tenant Units (MTU) and Multiple Dwelling Units (MDU) markets because of its interface simplicity and high data rate. The patent will strengthen Infineon’s dominance in this lucrative market,” said Noam Alroy, Infineon’s Vice President and General Manager Access 2. “Adding 10BaseS to our broadband access portfolio and our highly integrated LAN switching ICs has enabled us to offer our customers all the communications building blocks they need for a cost effective, high performance MTU/MDU solution.“

About 10BaseS™ Technology

The inventors of record are Dr. Peleg Shimon and Dr. Porat Boaz, Chief Scientists Access 2 at Infineon Technologies and Noam Alroy. Additional inventors include Rubinstain Avinoam and Sfadya Yackow who held leading positions in 3COM’s Network System Business Unit when the patent application was filed in 1997.

10BaseS is a highly integrated, low-power, Quadrature Amplitude Modulation (QAM) solution. It utilizes frequency division multiplexing (FDM) to separate downstream channels from upstream channels as well as to separate both downstream and upstream channels from POTS signals. Unlike standard Ethernet, it does not require costly Cat 5 cabling. It makes use of the existing copper infrastructure, while maintaining full integrity for distances of over 4000 ft.

10BaseS provides glue-less compatibility with RMII, SMII, seven wire and IEEE 802.3 Ethernet MII interfaces reducing design complexity, cost and time to market. Configured as a standard Ethernet PHY it can be used in switch, DSLAM or Network Interface Card (NIC) applications. The chipset can also be configured as a Media Access Controller (MAC) for standalone control of Ethernet PHY devices in customer premise equipment applications.

Infineon introduced its 10BaseS chipset last year at the June SuperComm 2000 conference held in Atlanta, Ga. With less than 1.5 W power consumption, an internal controller, and the underlying robust operation of VDSL the 10BaseS™ chipset is a highly competitive solution in today’s broadband market.

Pricing and Availability

The 10BaseS™ chipset is priced at $23 for quantities of 500K. Volume shipments are available now.
