Lattice Semiconductor and Dune Networks have announced that they will collaborate in the development and marketing of SPAUI-based networking solutions.
Dune Networks' FAP traffic managers provide ingress and egress programmable traffic management solutions that address the requirements of the MEF, IETF DiffServ, and DSL Forum TR-059/TR-101.
LatticeSCM FPGAs will provide the programmable platform bridge to switch fabrics and traffic managers by utilizing hardened Ethernet and SPI4.2 blocks implemented via its Masked Array for Cost Optimization (MACO) technology.
SPAUI is a serial interface based on the 10 GbE XAUI and SPI4.2 standards. By combining the benefits of both into one comprehensive standard, SPAUI enables system designers to take advantage of the ubiquity of XAUI as a physical layer as well as the multi-channel QoS and flow control mechanisms of SPI4.2. SPAUI is also designed to support aggregate rates of higher speeds. SPAUI is one of the interface options of Dune Networks' SAND chipset.
When implemented in a LatticeSCM-15E FPGA with a space-saving 256 fine pitch Ball Grid Array (fpBGA) package, the Lattice XAUI to SPI4.2 bridging solution requires only 17 mm × 17 mm on a printed circuit board while consuming only 2.5 Watts of power.
SPAUI, an interface based on the XAUI industry standard, incorporates several extensions that provide 10 Gbps applications with speedup (for packet headers, full rate 12GE), channelization, packet interleaving, and refined flow control. SPAUI is implementation-friendly, backward compatible to standard XAUI and ideal for dense 10GE and higher speed Ethernet solutions. The SPAUI memorandum is available upon request from Dune Networks at no cost.
