LEDA Systems® and Modelware® Announce Partnership for Silicon Proven SPI 4 Phase 2 Semiconductor IP providing 10 Gb/s Transport Solutions for Communications Systems-on-a-Chip

Integrated Physical and Link Layers Solution to be Utilized in High Speed SONET/SDH and Other Networking Applications

San Jose, Calif., Mar. 19, 2002, - LEDA Systems® Inc., a leader in the design of analog and mixed signal IP for communications systems, today announced at the Optical Fiber Communications Conference the immediate availability of the LaSer SPI 4.2 (System Packet Interface Level 4 Phase 2) front-end macro for interfacing Physical (PHY) and Link layer devices. This new offering is compatible with the Optical Internetworking Forum's (OIF) SPI-4 Phase 2 standard also known as SATURN® Development Group's POS-PHY Level 4 (PL4) interface. The LaSer SPI4.2 Physical Layer front-end macro interfaces seamlessly with Modelwares SPI4.2 Foundation and SPI4.2 Manager Link Layer soft cores to provide a complete SPI4.2 solution.

The SPI 4.2 interface has become a very popular standard in our industry," said Doug McCafferty, CEO of LEDA Systems. Providing a silicon verified SPI 4.2 interface is critical to our customers and lets users rapidly bring products to market that meet specifications and are delivered on time."

The LaSer SPI 4.2 has LVDS transceivers, which are programmable for 311/400/622/800 MHz links. The quad LaSer SPI 4.2 transceiver can handle up to 12.5 Gbps bandwidth in each direction, or up to 25 Gbps full-duplex bandwidth.

The LaSer SPI 4.2 product provides networking system architects the intellectual property they need. The SPI-4 phase 2 interface is preferred by most 10G system designers. The LaSer SPI 4.2 can be used in high speed optical networking applications such as high-end router and switch backplane links, and provides high bandwidth connections between chips, boards and systems. Currently implemented with 0.15 micron and 0.13 micron CMOS processes from TSMC and UMC foundries, the LaSer SPI 4.2 IP is available to license from LEDA Systems. LEDAs verified LaSer IP comes with a test board and characterization report but is also customizable to meet customer-specific requirements.

Modelware is pleased to be working with LEDA Systems," said Anthony Dalleggio, Executive VP of Modelware. The combination of Modelwares Link Layer integrated with LEDAs Physical Layer provides an easy to use, proven, and complete SPI-4 Phase 2 solution."
