Infineon Introduces Industry´s Most Flexible Chip to Deliver Ethernet Services Over Existing Metropolitan Networks

Dec 1, 2003 | Market News

Munich, Germany – December 1, 2003 – Infineon Technologies (FSE/NYSE: IFX) today announced the addition of an EoS (Ethernet-over-SONET/SDH) framer/mapper to its portfolio of optical networking products. The new MetroMapper™ 622 chip will enable both data communications and traditional telecommunications equipment vendors to develop flexible systems that support current and emerging Ethernet/data transport services over existing metropolitan-area optical fiber networks.

Infineon is the first supplier in the industry to offer a complete portfolio of optical networking solutions for any implementation, from pure voice-only SONET/SDH to resilient packet ring (RPR) and EoS. The MetroMapper 622 chip provides unsurpassed flexibility by performing VCAT (virtual concatenation), GFP (Generic Frame Protocol) and LCAS (Link Capacity Adjustment Scheme) functions on-chip.

“The MetroMapper 622 chip represents the culmination of our continuing efforts to deliver the broadest portfolio of standards-based solutions to the optical networking market,” said Subodh Toprani, Senior Vice President and General Manager, Wireline Communications Business Group, at Infineon Technologies North America. “It squarely addresses the fastest growing communications market segment, which is using the SONET/SDH infrastructure to deliver Ethernet and data services, and complements our solutions for networks supporting ‘pure’ TDM and RPR applications.”

”Carriers and system vendors are unified in their desire to provide Ethernet-over-SONET services using the combination of GFP, VCAT and LCAS,” said Allan Armstrong, director of communications semiconductors at analyst firm RHK, Inc. “Framer/mappers that enable sophisticated new tributary capabilities will go a long way toward making EoS affordable and pave the way to the much desired and inevitable convergence of Layer 1 and Layer 2 processing.”

Use of the single-chip MetroMapper 622 framer/mapper will result in significant power, design complexity, software development and overall system cost savings for manufacturers of line cards for next-generation SONET/SDH equipment, routers and multi-service switching platforms. Infineon further decreases development costs and time to market for its customers by providing complete solutions, including easy-to-use API-based software device drivers and best in-class applications engineering support, in addition to the silicon and associated evaluation boards.

The MetroMapper 622 mapper/framer, the first member of a new family of networking ICs, allows equipment manufacturers to develop systems that meet the latest Ethernet transport requirements as defined by the Metro Ethernet Forum (MEF) and ITU-T, including seamless interface between private and carrier networks, and any-point-to-any-point connectivity. It is the only EoS chip to offer a hitless LCAS engine proven in a real network environment and extensive zero-packet-loss Layer 2 functionality on-chip. With 64 VCGs (virtual concatenation groups), it also has the highest VCG density in the industry.

An evaluation board is available for fast design-in and software development. The board includes a MetroMapper 622 chip, embedded CPU system, IBM PowerPC 266 MHz processor, embedded LINUX, software drivers, and a printed circuit board. Offered in a 1024-contact ball grid array (BGA) package, the MetroMapper 622 EoS framer/mapper is available now at a low-volume price of 280 US-Dollar.
