High-Performance Alaska(R) X 88X2088 Device Significantly

Lowers the Cost of 10 GbE Links

Marvell(R) (Nasdaq:MRVL), a technology leader in the development of extreme broadband communications and storage solutions, today announced the industry's first 10 Gigabit Ethernet (GbE) copper transceiver for IEEE 802.3ak 10GBASE-CX4 applications. The high-performance Alaska(R) X 88X2088 device significantly lowers the cost of 10GBASE-CX4 links by replacing costly optical links with copper. This copper breakthrough in 10 Gigabit physical layer technology provides a cost-effective solution for 10 GbE uplinks, connections between stackable switches and chassis-to-chassis connections. 10 Gigabit copper connections also provide a cost-effective solution for switch-to-server connections and server clustering within the data center or server farm. The Marvell Alaska X 88X2088 transceiver is available now in a 256-pin TFBGA package and is shipping to a select group of top tier networking OEMs. The 88X2088 device is being demonstrated at the NetWorld+Interop tradeshow in Las Vegas, Nevada, April 30th-May 1st at the Marvell booth (#5443).

Prior to the CX4 copper standard, optical links were the only 10 GbE interconnect solutions as specified by the IEEE. Optical links are significantly more expensive, requiring additional optical and electrical components as compared to copper links, thus increasing overall system cost. In addition, optical links involve more active components that can often compromise the reliability of the connection. The use of copper cables will allow systems vendors to offer highly reliable, lower cost alternatives to optical solutions for short distance applications such as stacking links between switch systems.

"Marvell invented the concept and demonstrated the feasibility of 10 Gigabit Ethernet over copper last year by using Infiniband copper cables," stated Kamal Dalmia, Marvell's Product Marketing Manager for the Transceiver Products Group. "We are pleased to see that IEEE has adopted this approach for the CX4 standard which promises to deliver the price points necessary for widespread deployment of 10 Gigabit Ethernet technology."

The Alaska X 88X2088 transceiver delivers reliable 10 Gigabit operation, as per the IEEE 802.3ak draft standard, over fifteen meters of 8-pair cable. The Alaska X device is optimized for use as a signal conditioner device in copper versions of XAUI-based 10 Gigabit Ethernet modules such as XENPAK, X2 and XPAK. Providing a copper option for these hot plugable form factors allows tremendous flexibility to IT managers.

The Marvell Alaska X transceiver uses sophisticated signal processing and circuit design techniques to achieve the longest cable reach in the industry. The Alaska X device uses programmable transmit pre-emphasis and receive equalization signal processing techniques to compensate for cable impairments such as Inter-Symbol Interference (ISI) and cross talk. These signal-processing techniques yield reliable operation over high loss and high distortion environments providing the margin required to guarantee robust operation. In addition, the Alaska X transceiver features superior jitter performance providing extra timing margin.
