MUNICH -- Infineon Technologies AG today introduced an eight-channel chip set for high-density Ethernet or Digital Subscriber Line Multiplexers (DSLAM) applications based on the company's proprietary 10BaseS technology, which extends Ethernet networks over existing copper-wire infrastructure.
The new chip set is targeted at multi-tenant unit/multi-dwelling unit (MTU/MDU) applications, such as Ethernet switches and DSLAM line cards.
"The MTU/MDU market has seen substantial growth in the past year and Cahners In-Stat Group latest report estimates the worldwide MTU market will grow from $1.2 billion in 2001 to $9.8 billion in 2005," said Shlomo Berkovitch, general manager of Infineon's broadband access business unit. "Density and cost are singled out as the critical criteria for next-generation MTU/MDU systems and with Infineon's self contained Octal-10BaseS chipset MTU/MDU systems vendors will experience a dramatic cost reduction as well as shorter time to market."
Infineon said the chip set provides more than 25% total cost savings per port over existing solutions.
The 10BaseS technology has been developed as an Ethernet over VDSL quadrature amplitude modulation (QAM) solution. The standard line rate is a full duplex, 12.5 megabits per second. It transfers Ethernet packets transparently. The line rate is programmable to reach up to 15.6 Mbps, said Infineon. Special implementations that support up to 25 Mbps are also possible, according to the company.
The Octal-10BaseS chip set will be available in fourth quarter of 2001. The three-chip solution is comprised of: PEF22824 (digital transceiver), PEF22825 (analog front-end) and 8xPEF22810 (line driver). The price per port is $15 each in quantities of 50,000 chip sets, or 400,000 ports.
