Fujitsu selects AMCC's QT2225, a dual port XAUI-to-10GBASE-KR PHY IC

Fujitsu has selected the AppliedMicro's QT2225, a low power dual port XAUI-to-10GBASE-KR PHY IC designed for transmission of serial 10 Gbps Ethernet connectivity over one meter of PCB/backplane. The QT2225 includes integrated IEEE Std. 802.3apTM-2007 FEC with bypass and can operate in both 10GBASE-KR and 1000BASE-KX mode. Interoperability has been demonstrated with other 10GBASE-KR vendors and in multiple blade system configurations.

The QT2225 provides a high performance interface between a MAC or switch device and copper media including twinax cable and 10GBASE-KR backplanes. The data rate is switchable to 1.24 Gbps, allowing 10000GBASE-KX / 10GBASE-KR support on a single backplane.

Other key features include,

Dual port 1G / 10G: 1 / 10GE LAN / WAN & 1 / 10GFC
Advance EDC engine with auto tap weight adjustment & tracking
10G high-speed interface with integrated EDC and trasmit wave shaping
XAUI interface with equalization and transmit wave shaping
Integrated loopbacks and test features
Compliant to applicable IEEE & INCITS Specs

And the suggested applications are, Hostboard termination for SFP+ / SFP limiting modules including 10GBASE-SR, -LR & 1000BASE-X Hostboard termination for XFp modules including 10GASE-R & -W protocols.

"Ethernet backplane serial connectivity at 10 Gbps data rate is highly desirable for server virtualization and consolidation applications but it must come with robust performance and low cost," said Bernhard Brandwitte, director of Product Marketing for x86 Servers at Fujitsu Technology Solutions. "AppliedMicro's QT2225 device brings that high-speed connectivity to server backplanes through 10GBASE-KR application. The PHY excels in harsh blade system environments and enables a low per-port system cost through a high level of integration and reduced system complexity."

"As one of the world's leading server vendors, Fujitsu Technology Solutions was concerned about the key design areas that create bottlenecks in I/O performance. AppliedMicro's design team worked closely with Fujitsu to ensure that the QT2225 met the lossy, high noise conditions of a blade system backplane," said Sandeep Gupta, GM of Transport Products at AppliedMicro. "Through this type of close cooperation, AppliedMicro has developed a PHY technology that can tackle the demanding conditions of today's data centers, placing the company in an ideal position as 10GBASE-KR technology starts to hit high-volume production."
