Dual 10-GbE PHY ICs boost port density in backplanes

Sunnyvale, Calif.—Applied Micro Circuits Corp. announced the QT2225 and QT2235 dual-port XAUI-to-10Gb PHY devices.

The QT2225 supports the 10GBASE-SR/LR/LRM SFP+ optical modules and 10GBASE-KR 10G serial backplane connectivity applications. The QT2235 supports system cards using XFP optical modules.

The QT2225/QT2235 devices are highly integrated ICs for 10GbE, Fibre Channel, LAN, WAN and SAN applications based on XFP and SFP+ optical transceiver modules. The QT2235 supports XFP modules and the QT2225 is suited for high port density 10G datacom Ethernet switches, NICs, and telecom line card applications with SFP+ optical module requirements.

The QT2225 supports all SFP+ applications, including 10GBASE-LRM where there is a large installed base of multimode fiber (MMF) in corporate backbones. The can operate over 300m of FDDI-grade fiber to provide a cost-effective way to convert these links from speeds as low as 100-Mbits/s to high performance 10-Gbits/s operation.

The QT2225 is also designed to support the IEEE802.3ap 10GBASE-KR standard for backplane serial connectivity with a reach of up to 1 meter of PCB. It also provides an optimal design for blade server and high-performance computing system applications.

In addition to 10GbE support, the QT2225 also handles 1GbE data rates to enable backward compatibility and a simple migration path from 1GbE to 10GbE data rates in legacy system card and backplane environments. Lane 0 of each XAUI channel can be independently configured to operate at either a 1.25 Gbits/s or 3.125 Gbits/s data rate, and passed through to the serial high-speed port to be transmitted/received as either a 1GbE or 10GbE signal.

The QT2225 and QT2235 are sampling now to alpha customers. General availability is scheduled for the first quarter of 2008.
