Marvell Alaska X World's First Dual 10 GbE XAUI SERDES

8/6/2002 - Marvell®, a technology leader in the development of extreme broadband communications solutions, introduced the world's first dual 10 Gigabit Ethernet XAUI serializer/deserializer (SERDES) physical layer device. The new Alaska® X device (88X2080) enables XAUI redundancy and repeater applications while delivering unprecedented density, performance and power.

The Alaska X device features two 10 Gigabit Media Independent Interfaces (XGMII) and two 10 Gigabit Attachment Unit Interfaces (XAUI) that are fully compliant to the IEEE 802.3ae specification. The 88X2080 device is the industry's first and only 10 Gigabit Ethernet compliant dual XAUI to dual XGMII converter IC. In addition to 10 Gigabit Ethernet, the device supports 10 Gigabit Fiber Channel (10 GFC) applications.

The Alaska X device simplifies the design of high-reliability, fault-tolerant switching systems by providing highly flexible redundancy features. The transceiver's redundancy features allow 'on-the-fly' connection of the system XGMII interface to a primary XAUI interface or a redundant XAUI interface for fail-over protection. This capability eliminates the need for additional expensive components to do the switchover, resulting in simplified designs and significant cost savings. The Alaska X device is also optimized for XAUI re-timer and repeater applications such as signal clean-up in IEEE 10GBASE-LX4 WWDM optical modules, enabling streamlined single-chip repeater solutions. The two XAUI interfaces of the device can be connected to each other to implement full bi-directional XAUI-to-XAUI transceiver for repeater applications.

"Marvell has consistently demonstrated technology leadership with its Alaska X family of 10 Gigabit physical layer devices," said Tony Moretti, Vice President of Advanced Optoelectronic Development at Molex, Inc. "The Alaska X devices are the optimal choice for a variety of applications due to their highly flexible and versatile feature set."

"There is a growing demand for highly reliable 10 Gigabit Ethernet systems for enterprise and metropolitan area networks," stated Gary Smerdon, Marvell's Vice President of Marketing for the Communications Business Group. "Marvell continues to Raise the Technology BarTM by offering the first dual 10 Gigabit Ethernet transceiver-the industry's only solution available today that can bring the density, power and cost to the levels needed for widespread adoption of 10 Gigabit Ethernet technology."

Marvell Alaska X Product Information
The Marvell Alaska X dual 10 Gigabit Ethernet XAUI device incorporates eight SERDES lanes each with a selectable 8B/10B encoder/decoder. The eight lanes can be configured as two groups of four to implement two XAUI interfaces or can be configured independently as eight separate lanes. The XAUI modes of operation support 10 Gigabit Ethernet applications at 3.125 Gbps and 10 Gigabit Fiber Channel applications at 3.1875 Gbps. The device seamlessly connects to optical modules such as the XENPAK, X2 and XPAK using the XAUI interfaces, and to 10 Gigabit Ethernet switch devices using the XGMII interfaces.

The Marvell Alaska X (88X2080) transceiver uses sophisticated signal processing and circuit design techniques to achieve the industry's highest performance in stringent copper environments such as FR4 backplanes and copper cables. The Alaska X device uses programmable transmit pre-emphasis signal processing technique to compensate for inter-symbol interference (ISI) caused by the copper media. The Alaska X device also features flexible amplitude adjustment capability. Programmable amplitude, coupled with flexible transmit pre-emphasis, yields reliable operation over high loss and high distortion environments such as 15 meters of unequalized copper cable and 60 inches of backplane FR4 PCB traces with multiple connectors.

The Marvell Alaska X 88X2080 device, available in a 448-pin PBGA package, is now sampling.
