Stratix II 90-nm FPGA Family

The Stratix® II FPGA family, the second generation in Altera's high-end FPGA series, is the most recent family to have been fully characterized to military temperature grade. Although superseded by new generations in the Stratix series, devices in the 90-nm Stratix II family are still recommended for new designs in certain circumstances.

Applications requiring the extended military temperature range are the most obvious of these, but there are others. For example, the Stratix II GX FPGA still provides a robust solution for designs requiring immediate delivery of transceiver-based solutions up to 6.375 Gbps. However, devices in the Stratix III and Stratix IV FPGA families are the solution of choice in the majority of other high-end FPGA design circumstances.

Stratix II FPGA

With the Stratix II FPGA, Altera introduced a totally new logic cell architecture, the adaptive logic module (ALM), and refined the on-chip TriMatrix memory and the digital signal processing (DSP) block for even higher performance. A Stratix II FPGA can provide up to 180K equivalent logic elements (LEs), and up to 9.0 Mb of on-chip RAM arranged in TriMatrix memory blocks, operating at up to 450 MHz, with DDR2 memory interfaces operating at up to 667 Mbps. In 90-nm Stratix II FPGA family, the number of DSP blocks expanded to 96 in the largest device, giving a maximum of 384 18x18 multipliers.

Stratix II GX FPGA

Building on established high-performance architectural features, the Stratix II GX FPGA extended the capabilities of the high-end Stratix II FPGA with on-chip transceivers. Using a transceiver block supporting four full-duplex channels and clock data recovery (CDR) technology allows transmission of data in excess of 6.375 Gbps per channel. This data rate supports many common high-speed communication protocols including SerialLite II, Gigabit Ethernet, 10-Gigabit Ethernet/XAUI, SONET OC-12 and OC-48, Fibre Channel, the Serial RapidIO® standard, PCI Express® Gen2, and high definition (HD), standard definition (SD), and 3G-SDI.
