NOVEMBER 6, 2007 -- Applied Micro Circuits Corp. (AMCC; search for AMCC) has unveiled 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 10-Gbit/sec market is expanding rapidly and system designers are seeking higher densities for their applications," stated Jag Bolaria, senior analyst for The Linley Group. "The QT2225 and QT2235 products allow customers to reduce the number of chips previously required in their designs by two. The blade server market is a key driver for high-density 10-Gbit/sec backplane applications while the switch/router market is a key driver for greater 10-Gbit/sec port density on line cards. Those industries should be very interested in these two highly integrated products. This announcement demonstrates AMCC's continuing commitment to this market and provides the company with one of the largest 10GbE PHY portfolio offerings in the industry."
The QT2225/QT2235 devices are aimed at 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 targeted at high-port-density 10G datacom Ethernet switches, NICs, and telecom line card applications with SFP+ optical module requirements. AMCC says it has performed extensive and successful testing with multiple optical module vendors to deliver maximum standard performances and also to build a large ecosystem to help customers reduce their design cycle times.
The QT2225 is designed to support all SFP+ applications, including 10GBase-LRM where there is a large installed base of multimode fiber in corporate backbones. The QT2225 incorporates electronic dispersion compensation (EDC) and signaling conditioning functions and can operate over 300 m of FDDI-grade fiber.
The QT2225 is also designed to support the IEEE802.3ap 10GBase-KR standard for backplane serial connectivity with a reach of up to 1 m of PCB. It also meets design requirements 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- or 3.125-Gbit/sec 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 Q1 2008.
