The Stratix® II GX FPGA provides a strong solution for the growing number of applications and protocols requiring multi-gigabit serial I/O. The Stratix II GX FPGA transceiver architecture provides robust noise immunity and excellent jitter performance across an operating range of 600 Mbps to 6.375 Gbps, while maintaining the lowest power consumption. Stratix II GX FPGAs, available in production today, are built using the industry’s fastest and highest-density Stratix II FPGA fabric and integrate up to 20 serializer/deserializer (SERDES)-based transceivers.

Signal Integrity

Stratix II GX FPGA transceiver architecture successfully operates at data rates up to 6.375 Gbps on transmission lines to 50" (1.25 m) in length, on boards and backplanes fabricated on standard FR-4 material, and up to 30 m of PCIe cable at 2.5 Gbps. To achieve this, the transceivers include a number of features to ensure signal integrity at these higher data rates, while maintaining low power. These include:

Complete Protocol Solution

The Stratix II GX FPGA is part of a complete solution to key protocols used in many of today’s high-speed serial applications. Support is provided for PCI Express, CEI-6G, serial digital interface (SDI), Gigabit Ethernet, Serial RapidIO® (SRIO), XAUI, SerialLite II, Fibre Channel, and SONET standards. The complete solution includes:

Innovative Logic Structure

The Stratix II GX FPGA is built on the innovative adaptive logic module (ALM) logic structure found in the Stratix II FPGA, using TSMC's 90-nm, low-k dielectric process technology, optimized to maximize performance and control power leakage. A Stratix II GX FPGA can provide up to 20 high-speed serial transceivers and up to 130 K equivalent logic elements (LEs), 6.7 Mbits of embedded memory with up to 252 (18-bit x 18-bit) multipliers for efficient implementation of high-performance filters and other digital signal processing (DSP) functions. Key features of the Stratix II GX FPGA architecture include:
