Lattice FPSC Drives Gigabit Ethernet Capability in Fujitsu FLASHWAVE 4100 Multi-service Platform

HILLSBORO, Oregon - May 19, 2003 - Lattice Semiconductor (NASDAQ:LSCC) today announced that Fujitsu Network Communications Inc. (FNC) has selected the Lattice ORT8850L Field Programmable System Chip (FPSC) for use in its FLASHWAVE 4100 multi-service optical networking platform. The ORT8850L FPSC acts as a backplane driver for Gigabit Ethernet line cards available as an option for the FLASHWAVE 4100.

"Lattice's ORT8850L was used to quickly develop a high-speed backplane for adding Gigabit Ethernet over SONET capability to our FLASHWAVE 4100," said FNCector of Hardware Design, Basel Azzam. "The FLASHWAVE 4100 was designed specifically for convergence of voice and data at the edge of metro networks, and the Lattice FPSC technology provided the best platform for the job in terms of cost, time-to- market, and performance. The ORT8850L allowed FNC to develop our proprietary functionality in the programmable gates while leveraging the built-in SERDES channels to drive across the FLASHWAVE 4100 system backplane. This development path was much faster and easier than using ASICs, ASSPs, or struggling with a standalone FPGA and a discrete transceiver," he added.

"The selection of our ORT8850L FPSC for use in an industry-leading system like the FLASHWAVE 4100 once again demonstrates that our technology is ideal for networking applications where time-to-market, low-cost, scalability, and performance are key," commented Stan Kopec, vice president of marketing at Lattice Semiconductor. "The ORT8850L is a low-cost, high-value programmable platform for SONET-based backplane applications. Our SERDES technology has been acclaimed by our customers as best-in-class, and with products like our ORT8850L and the recently introduced ORT42G5, we are making this technology ever more accessible in a variety of low-cost configurations," Kopec added.

Lattice's FPSC devices are high-performance programmable devices that combine optimized embedded core functions together with flexible, general-purpose FPGA logic. The ORT8850 devices offer a clockless, high-speed interface for inter-device communication on a board or across a backplane. The built-in clock recovery of the ORT8850 FPSCs supports higher system performance, easier-to-design clock domains in a multi-board system, and fewer signals on the backplane.

The ORT8850 is available in medium- and high-density versions. While both feature eight channel, 850Mbits/s high-speed interfaces, the ORT8850L offers up to 400K system gates and 278 user I/Os. The ORT8850H offers up to 900K system gates and 297 user I/Os.

Additional ORT8850 Technical Information
Lattice's ORT8850 devices include the following features:

  • 8 channels of high-speed SERDES providing up to 850 Mbits/sec for a total chip bandwidth of 6.8Gb its/sec (full duplex)
  • Built- in Clock Data Recovery (CDR) with precise Phase Locked Loop (PLL) timing control
  • Built- in SONET scrambler / descrambler, Transport Overhead Handling (TOH) and streamlined SONET framing
  • Dedicated alignment FIFOrating across all 8 channels
  • 1.5V power supply for low power
  • Comprehensive general-purpose I/O support including GTL+, LVPECL, SSTL, HSTL, LVCMOS, DDR and others
  • General-purpose FPGA logic includes up to 900K system gates (8850H) per device
  • Up to 147 kilobits (8850H) of general-purpose Embedded Block RAM (EBR) per device
