Altera Announces Stratix II GX FPGAs with 50-Gbps SFI-5 Interface

Altera Corporation (NASDAQ: ALTR) announced SERDES Framer Interface Level 5 (SFI-5) standard support in its Stratix® II GX FPGAs with embedded transceivers, providing a 40- to 50-Gbps interface for high-performance optical communications applications. The SFI-5 specification is a chip-to-chip standard that ensures interoperability between forward-error correction (FEC) and the framer, as well as from industry-leading optical transponder devices. Hardware tested to verify compliance to the SFI-5 standard, Stratix II GX FPGAs feature up to 20 high-speed serial transceiver channels that can operate at data rates between 600 Mbps and 6.375 Gbps, easily satisfying SFI-5 interface requirements.

The SFI-5 Optical Internetworking Forum (OIF) specification was developed to provide an interface between the network processing devices and the optical transponder to enable higher bandwidths. The SFI-5 standard addresses network transport formats including OC-768, STM256, and OTN OTU-3. In addition to supporting the SFI-5 standard, Altera® Stratix II GX FPGAs are designed to deliver an extensive set of optical and electrical protocols with low power and industry-leading signal integrity, making them an ideal solution for use in all high-speed designs.

“The SFI-5 standard, as implemented in our Stratix II GX FPGAs, is being adopted rapidly by high-performance optical communications systems,” said David Greenfield, senior director of product marketing, high-end products, at Altera Corporation. “For designers developing next-generation wireline communications applications, our Stratix II GX FPGAs easily exceed the demanding SFI-5 signal integrity and skew requirements with ample margin.”
