Lattice Semiconductor Announces World's First 2.7 Gigabit SONET Backplane Field Programmable System-on-a-Chip

HILLSBORO, OR - OCTOBER 21, 2002 - Lattice Semiconductor Corporation (NASDAQ: LSCC) today announced the availability of the ORSO82G5 Field Programmable System-on-a-Chip (FPSC), the world's first SONET-based programmable backplane transceiver, incorporating eight SERDES channels each running at 1.0 to 2.7 Gbits/sec, plus embedded SONET core functionality along with 400K field programmable gates based on Lattice's ORCA® Series 4 FPGA architecture.

"This latest device vividly demonstrates the power of the FPSC concept," said Stan Kopec, vice president of corporate marketing at Lattice. "The ORSO82G5 is a perfect fit for the Metropolitan switching and transport space, where SONET-based technology is prevalent and is well-suited for serial transport of payload and control data. The efficiency of our embedded SONET functionality coupled with the flexibility of our FPGA technology makes this device an all-around winner."

Lattice's FPSC devices are high-performance programmable devices that combine optimized embedded core functions together with flexible, general-purpose FPGA logic. In addition to its eight SERDES cores and 400K ORCA FPGA gates, the ORSO82G5 includes embedded pseudo-SONET framer plus multi-channel alignment capability without using any FPGA gates. At 210mW per channel (worst case) the device offers designers the highest available bandwidth (up to 2.7Gbps) for SONET applications at very low power consumption. "The ORSO82G5 can support eight OC-48 SONET channels or two OC-192 SONET channels in a single device. All the necessary SONET scrambling and descrambling, overhead updates and payload processing needed for backplane applications is also performed in the embedded core. Plus, with 400K programmable gates, the device can support additional data and overhead processing. The overall capability is unbeatable," added Kopec.

The device also features 372 programmable user I/Os supporting a variety of advanced interface standards including LVCMOS, LVTTL, LVDS, Bus-LVDS, LVPECL, HSTL, SSTL3/2, GTL, GTL+, ZBT and DDR to facilitate easy interfacing. With the addition of protocol and access logic such as protocol-independent framers, asynchronous transfer mode (ATM) framers, packet-over-SONET (POS) interfaces, and framers for HDLC for Internet protocol (IP), designers can build configurable interfaces retaining proven backplane driver/receiver technology. The ORSO82G5 can also be used to provide a full 10 Gbits/s backplane data connection with protection between a line card/redundant line card and switch fabric/redundant switch fabric. The FPGA portion can be used to implement 2.5G or 10G SONET-based switch fabric interfaces.

Another FPSC device in the Lattice backplane portfolio, the ORT82G5, supports 8b/10b encoding/decoding and link state machines for 10Gbit Ethernet (XAUI) and Fibre Channel applications. The ORSO82G5 is completely pin compatible with the ORT82G5 device. The ORSO82G5 provides an alternative to the popular 8b/10b encoding scheme commonly used in Ethernet-based systems that utilizes the relatively low overhead SONET framing scheme. It is an ideal companion to many of the popular SONET-based cross-connect and packet-switching ASSPs on the market today.

To document the superior characteristics of its SERDES technology, Lattice has also just released its new SERDES Handbook. This Handbook provides actual data on the typical eye diagrams, jitter, lock time, and other key operational aspects of the SERDES technology used in the ORSO82G5. It is available in electronic form on the Lattice website at http://www.latticesemi.com.
