1 October 2003 Munich Lightwave -- Infineon Technologies AG and Vitesse Semiconductor Corp. have announced a collaboration to establish interoperability of currently available and future-generation SONET/SDH framer integrated circuits (ICs) and Time Slot Interchange ICs (TSIs).

Working together, Infineon and Vitesse intend to provide system designers with a complete end-to-end solution of critical silicon content for SONET/SDH systems. Interoperability between the Infineon framers and the Vitesse TSIs includes products from each company's SONET/SDH roadmap for 160 Gbits/sec, 320 Gbits/sec and 640 Gbits/sec SONET/SDH systems, as well as system-level reference designs that are useful for rapid development and deployment of next-generation systems.

The first result from this collaboration is the proven interoperability between the Infineon Tethys SONET/SDH Multi-Rate Framer IC and the Vitesse VSC9185 TSI. Achieving interoperability with the VSC9185 is important from an industry perspective because it is part of the Vitesse TSI product family that, according to industry analysts, has captured 30% of its market, making it one of the most widely used TSI product lines in the industry.

Test results from the Tethys framer and VSC9185ITSI reference design and supporting software clearly demonstrate interoperability in terms of such key parameters as signal integrity; clock synchronization; frame alignment; and automated, manual, and hitless switching. Electrical compatibility and logical compatibility, including AC and DC coupling, optical connectivity, and SONET framing at 2.5 Gbits/sec were shown to work error-free. In a test configuration using an FR4 backplane, a 0 BER (bit error rate) was achieved over a 15-hour operating period.

The reference design and all related software and documentation for operation are now available and can be used by SONET/SDH system operators and manufacturers to upgrade circuit-handling capacity by integrating Tethys framer-based line cards into their existing hardware.

"This is an extremely important event," contends Jeff Camillo, product marketing manager for the Infineon North America Communications Business Group, "because it means our customers can be assured of compatibility between our framers and one of the most widely used TSI product families in the industry, both now and in the future. We expect the relationship with Vitesse to be beneficial for everyone involved, but especially for the system OEM, who can now more easily achieve seamlessly integrated, high-density systems."

The companies are now focused on interfacing their TFI-5-compliant devices, such as Vitesse's VSC9195, a 340-Gbit/sec, 136-channel, non-blocking TSI, and Infineon's Tethys Multi-Rate Framer. Use of a TFI-5interface ensures a seamlessly integrated solution for next-generation SONET/SDH system deployments, resolving such system issues as automatic protection switching (APS) and performance monitoring. Used in conjunction with bit-slicing functionality, this solution provides more efficient scaling to high-density switch matrices in a lower power, denser form factor than a traditional three-stage architecture, say the companies.
