has announced complete solutions for the Optical Internetworking Forum (OIF) System Packet Interface (SPI) 4.2 and SerDes Framer Interface
(SFI) 4.1 standards, the industry's highest performance channelized packet
Based on its high-performance Virtex-5 LXT FPGAs, these solutions feature the ML550 hardware verification board, SPI-4.2 LogiCORE IP and SFI-4.1 reference design. Verified across multiple FPGA platforms, the solutions accelerate the design cycle of wired networking systems that require OC-192 (10 Gbps), multiple OC-48 (2.5 Gbps) or 10 Gbps Ethernet interfaces and are claimed to result in faster time-to-market than competing solutions.
The Xilinx ML550 board is said to be ideal for the development and evaluation of OIF and other networking interfaces, allowing designers to implement high-speed applications with extreme flexibility. Xilinx's ChipSync technology, available only in Virtex-5 FPGAs, provides accurate dynamic alignment of clock and data using 75 ps programmable delays, enabling improved timing and reliable operation under changing system conditions.
The Xilinx SPI-4.2 LogiCORE IP, which is fully compliant with the OIF SPI-4.2 standard, interconnects physical layer ASSPs to link layer FPGA devices in a wide range of networking applications and multi-service DWDM and SONET/SDH-based transport systems. The Xilinx SPI-4.2 IP core provides proven interoperability with industry leading ASSPs and is claimed to provide up to 20 percent higher data bandwidth due to optimized payload efficiencies as compared to competing FPGA offerings.
The Xilinx SFI-4.1 reference design supports up to 710 Mbps/channel with dynamic alignment to provide a robust solution for OC-192 framer interfaces.
Pricing and availability
The SFI-4.1 reference design is immediately available free of charge. The SPI-4.2 LogiCORE IP is available for a free evaluation and can be purchased for an $18,000 site license fee. For more information, please visit www.xilinx.com/spi_sfi.
