Altera® Stratix® IV FPGAs deliver a breakthrough level of system bandwidth and power efficiency for high-end applications, allowing you to innovate without compromise. Stratix IV FPGAs are based on the Taiwan Semiconductor Manufacturing Company (TSMC) 40-nm process technology and surpass all other high-end FPGAs, with the highest logic density, most transceivers, and lowest power requirements.

The Stratix IV device family contains three optimized variants to meet different application requirements:

■ Stratix IV E (Enhanced) FPGAs—up to 813,050 logic elements (LEs), 33,294 kilobits (Kb) RAM, and 1,288 18 x 18 bit multipliers

■ Stratix IV GX transceiver FPGAs—up to 531,200 LEs, 27,376 Kb RAM, 1,288 18 x 18-bit multipliers, and 48 full-duplex clock data recovery (CDR)-based transceivers at up to 8.5 Gbps

■ Stratix IV GT—up to 531,200 LEs, 27,376 Kb RAM, 1,288 18 x 18-bit multipliers, and 48 full-duplex CDR-based transceivers at up to 11.3 Gbps

The following list summarizes the Stratix IV device family features:

■ Up to 48 full-duplex CDR-based transceivers in Stratix IV GX and GT devices supporting data rates up to 8.5 Gbps and 11.3 Gbps, respectively

■ Dedicated circuitry to support physical layer functionality for popular serial protocols, such as PCI Express (PCIe) (PIPE) Gen1 and Gen2, Gbps Ethernet (GbE), Serial RapidIO, SONET/SDH, XAUI/HiGig, (OIF) CEI-6G, SD/HD/3G-SDI, Fibre Channel, SFI-5, and Interlaken

■ Complete PCIe protocol solution with embedded PCIe hard IP blocks that implement PHY-MAC layer, Data Link layer, and Transaction layer functionality
