• 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
• SONET/SDH and Fibre Channel applications

Procurement Notes

Verify the specific speed grade suffix 'C5' against official datasheet tables, as the provided source material lists '-5', '-6', and '-7' grades without explicitly defining 'C5'. Confirm package availability in the 1,020-pin FineLine BGA format. Ensure design compatibility with the 1.5-V core voltage requirements specified for the Stratix GX family.

Selection Notes

Select this model for designs requiring 16 dedicated serial transceivers within a single device. Compare resource utilization against the EP1SGX10D (8 channels) and EP1SGX40G (20 channels) variants. Verify that the 1,020-pin package dimensions fit the target PCB layout constraints. Check I/O pin counts for specific interface requirements.

Part Context

This component belongs to the Stratix GX FPGA family, which integrates high-performance logic arrays with high-speed serial transceivers. It represents a scalable architecture designed for low power consumption and small die size. The family supports vertical migration between devices like the EP1SGX10C and EP1SGX25C within compatible packages.

Replacement Considerations

EP1SGX25DF1020C6 or EP1SGX25DF1020C7 offer higher speed grades within the same package. EP1SGX40DF1020C5 provides increased logic resources and transceiver channels. Cross-reference I/O pinouts for migration compatibility.
