Solarflare CTO to Speak on Energy Efficient 10GBASE-T Transceiver Design at the International Solid-State Circuits Conference

IRVINE, Calif.—(BUSINESS WIRE)—February 10, 2009— Solarflare CTO, Dr. George Zimmerman, will give a talk on advanced energy efficient transceiver design for the IEEE 10GBASE-T standard during the International Solid-State Circuits Conference (ISSCC) in San Francisco, CA, February 8-12, 2009. Part of the High-Speed Interfaces forum, Dr. Zimmerman’s session will focus on design considerations to minimize power and maximize the utility of a single-chip 10GBASE-T solution.

Date and time:
Thursday, February 12 at 2:15pm PT
‘Complexity, utility and energy efficiency for copper Ethernet at 10Gb/s and beyond’
San Francisco Marriott Hotel, San Francisco, CA
George Zimmerman, Solarflare CTO

The High-Speed Interfaces forum goal is to provide circuit designers with an opportunity to learn from leading experts about the design issues and system-level challenges that arise in the development of transceivers for a wide cross-section of application areas and associated standards. In his talk, Zimmerman will review tradeoffs made with prior serial Ethernet standards and discuss perspectives on changes expected for emerging standards, including both higher-speed and Energy-Efficient Ethernet. The impact of power and complexity tradeoffs on transceiver, systems and facilities level efficiencies will be addressed, showing how overall complexities can sometimes be different than those viewed at the transceiver level.
