Lattice Semiconductor Extends Programmable SERDES Leadership with Introduction of 4 Channel Field Programmable System Chip Device

ORT42G5 FPSC offers 4 channels of 3.7 Gbps SERDES plus over 10,000 Logic Elements in small footprint BGA package

The device is targeted at high speed chip-to-chip and backplane applications such as 10Gigabit Ethernet, 1Gigabit and 2Gigabit Fibre Channel, and 10Gigabit Fibre Channel for the rapidly expanding 10Gigabit storage area networking market.

"With the introduction of the ORT42G5, Lattice is extending its leadership position in the programmable SERDES market," said Stan Kopec, vice president of corporate marketing at Lattice. "Our portfolio of SERDES-based devices is already the broadest in the industry, and the ORT42G5 offers a cost-effective device that will save designers board space and reduce trace routing and complexity. We've packed 4 channels of the industry's fastest production SERDES along with plenty of programmable logic for bridging and proprietary packet processing functions. The competition requires at least two chips to accomplish what we can do in a compact 23x23mm footprint," Kopec added.

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 four SERDES channels and over 10,000 ORCA(R) FPGA logic elements for general-purpose logic, the ORT42G5 includes fully embedded 8b/10b encoding, XAUI and Fibre Channel link state machines and multi-channel alignment capabilities. The SERDES on the ORT42G5 includes numerous best-in-class features:

--	3.7-0.6Gbps operating range per channel
--	less than 225mW per channel worst case at 3.125Gbps
--	Transmit jitter of 0.17UI at 3.125Gbps
--	Receive jitter of 0.75UI at 3.125Gbps
--	Drives at least 40 inches (1 meter) of FR-4 backplane at 3.125 Gbps
--	Fast Locking Times with bit realignment at 300 nanoseconds (938 bit times at 3.125 Gbps)

The device also features 204 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. Another FPSC device in the Lattice backplane portfolio, the ORT82G5, offers 8 channels of the same SERDES core.

To document the superior characteristics of its SERDES technology, Lattice has just released the second edition of its 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 ORT42G5 and ORT82G5 FPSCs as well as information on its ORSO82G5, ORT8850, ispGDX2(TM) and ispXPGA(TM) product families. It is available in electronic form on the Lattice website at http://www.latticesemi.com.
