Sandburst Easily Integrated SLE’s SPI-4.2 IP into Popular Ethernet Switch Fabric 12-07-2005

SLE today announced that its System Packet Interface 4 Phase 2 (SPI-4.2) -- intellectual property (IP) core was easily integrated into Sandburst’s QE-2000 application specific integrated circuit (ASIC), a 20 Gbps full-duplex integrated traffic manager/fabric interface device for Sandburst’s award-winning HIBEAM® Ethernet Switch Fabric. The HIBEAM® Switching Architecture is emerging as the OEM packet fabric of choice for next generation network systems that brings new levels of performance, scale and Quality of Service to high-end enterprise backbones, data centers, and metropolitan area networks.

SLE’s SPI-4.2 is available in 9 different technologies and easily portable to new technologies. SLE’s SPI-4.2 has been used in over 25 different chips to date.

“All of SLE’s designs, including our SPI-4.2, are optimized using our Think Physical™ process to produce ASIC designs that work,” said Jeff West, President of SLE. “SLE’s experience with high-end System-On-Chip (SOC) design greatly improves the quality of the IP we offer.”

The SPI-4.2 ASIC core includes both the physical and link layers and incorporates a proprietary real-time tuning algorithm. It is a fully digital, standard cell-based implementation that requires no technology-specific PLLs or DLLs. The core is ideal for packet and cell transfer in applications such as 10 Gb/s Ethernet, OC-192 ATM, and Packet over SONET/SDH.

Developed by the Optical Internetworking Forum, the SPI-4.2 standard is fast emerging as one of the most important integration standards in the history of telecommunications and data networking. It is a high-speed interconnection for 10 Gb/s aggregate bandwidth applications.

“We are very pleased with the integration process of SLE’s SPI-4.2 and their support,” said Karen Schramm, Vice President of Engineering at Sandburst. “SLE’s SPI-4.2’s ease of use has been critical for us to successfully meet our time-to-market goals.”
