| Broadcom Announces New 10 Gigabit Ethernet PHY Broadcom has announced the industry's highest performance and lowest power 10 Gigabit Ethernet (10GbE) PHY in support of the IEEE 10GBASE-KR standard for running 10 Gbps serial data over backplane systems. The new dual physical layer (PHY) device extends the life of today's existing systems that use four lanes to carry 10 Gbps (XAUI) data rates by providing a four times bandwidth improvement per channel. Today's blade servers and advanced telecommunications computing architecture (ATCA) equipment are self-contained, modularly designed computing systems that typically use a chassis, common backplane and Ethernet connectivity to transfer voice, video, data and multimedia within the system. However, these computing systems can only support single-channel, low bandwidth capabilities (using 1000BASE-X or 1000BASE-KX standards), or four-channel, low bandwidth per channel capabilities (using the 10GBASE-KX4 standard). With today's higher bandwidth applications (such as virtualization, security/encryption and multimedia), as well as the need to preserve existing systems running at 1 Gbps or XAUI data rates, serial 10 Gbps data must now be driven across the backplane. Broadcom was the first silicon vendor to address this market requirement in 2007 and is now introducing its second generation product that supports the new 10GBASE-KR standard for backplane systems. Announced is the Broadcom BCM8073 dual serial 10GBASE-KR-to-XAUI backplane PHY that builds upon five generations of field proven 10GbE serial PHY technology. Designed using 65 nanometer CMOS process technology that provides the industry's highest level of integration and lowest power consumption, the BCM8073 is an all digital signal processing (DSP)-based 10GbE PHY that provides enterprise data centers with higher bandwidth and performance, as well as significant savings in cost, resources and manpower when upgrading to 10GbE links. The BCM8073 has been verified on more than 300 existing backplane channels and has more than 3dB of margin over the worst case channels encountered in the customer base. The performance surpasses competing analog solutions that cannot sufficiently operate error free over these types of backplane channels. The BCM8073 dual serial 10GBASE-KRto-XAUI backplane PHY is the highest performing solution in the market exceeding the IEEE requirements for the 10GBASE KR standard and has the ability to drive over 40 inches of FR-4 with 3 backplane connectors. Its all DSP-based architecture allows diagnostic tools to monitor system and channel parameters such as insertion loss, channel frequency response, equalizer response and frequency offsets, in addition to key performance metrics such as bit error rate (BER) and signal-to-noise ratio (SNR). Other key features include: All DSP-based architecture with a fully adaptive datapath, which continuously adapts to changes in the backplane environment such as temperature variations and crosstalk. Multi-rate with support for 10GBASE-KR, 1000BASE-KX and 2.5 Gbps applications with auto-negotiation. Auto programmability with 10G transmitter pre-emphasis support. Integrated forward error correction (FEC) capabilities. Low power: 1.2 Watts. write your comments about the article :: © 2008 Networking News :: home page |
