• Integrates 25,660 logic elements and 1,944,576 total RAM bits across M512, M4K, and M-RAM blocks.
• Supports protocols including XAUI, Gigabit Ethernet, SONET/SDH, PCI Express, and Fibre Channel.
• Features programmable pre-emphasis, equalization, and output voltage settings for signal integrity optimization.

Applications

• High-speed backplane interface systems
• Chip-to-chip communication links
• Communications protocol bridging
• 10 Gigabit Ethernet attachment unit interface (XAUI) implementations

Procurement Notes

Verify the specific speed grade suffix (-6) against the datasheet Table 4 to confirm performance characteristics. Ensure the 1020-pin FBGA footprint matches the design constraints. Confirm that the operating temperature range of 0°C to 85°C aligns with system requirements. Cross-reference the I/O pin count of 607 with the package diagram in Table 2.

Selection Notes

Select this device for applications requiring high-density logic combined with significant serial bandwidth. The EP1SGX25D variant offers vertical migration compatibility with other EP1SGX25 devices in the same package. Consider the -6 speed grade if intermediate performance between -5 and -7 is required. Evaluate power consumption based on the number of active transceiver channels and logic utilization.

Part Context

This component belongs to the Stratix GX family, Altera's second FPGA series to integrate high-speed serial transceivers with a scalable logic array. The GX series is distinguished by its embedded Clock Data Recovery (CDR) technology and support for data rates up to 3.1875 Gbps. It serves as a bridge between general-purpose FPGAs and specialized ASICs for high-throughput networking and storage applications.

Replacement Considerations

EP1SGX25C: Offers similar logic density but fewer transceiver channels (4 or 8). EP1SGX25F: Provides 16 transceiver channels in the same package but may have different speed grades. EP1SGX40D: Contains more logic elements (41,250 LEs) and 8 transceiver channels in a 672-pin package, requiring board redesign.
