EP1SGX25DF672C6

Overview

The EP1SGX25DF672C6 is a Stratix GX Field-Programmable Gate Array (FPGA) manufactured by Altera. It features 25,660 logic elements and 1,944,576 total RAM bits. The device includes eight high-speed serial transceiver channels capable of full-duplex operation from 500 Mbps to 3.1875 Gbps. It operates with a 1.5-V logic array supply voltage and supports I/O standards including LVDS, LVPECL, and PCML. The component is housed in a 672-pin FineLine BGA package measuring 27x27 mm and is rated for an operating temperature range of 0°C to 85°C.

Feature Summary

• Contains eight high-speed serial transceiver channels with Clock Data Recovery (CDR) supporting data rates up to 3.1875 Gbps.
• Integrates TriMatrix memory technology comprising M512, M4K, and M-RAM blocks for flexible storage configurations.
• Includes dedicated Digital Signal Processing (DSP) blocks with embedded multipliers for FIR filter implementation.
• Supports programmable differential output voltage (VOD), pre-emphasis, and equalization for signal integrity optimization.

Applications

• High-speed backplane interface systems
• Chip-to-chip communication links
• Communications protocol bridging
• Digital Terrestrial Video Transmission System (DVB-T) implementations

Procurement Notes

Verify the specific speed grade suffix 'D' corresponds to the required timing performance for the target design. Confirm that the 672-FBGA package dimensions align with the PCB footprint constraints. Ensure the power delivery network supports the 1.5-V core voltage requirements specified in the datasheet.

Selection Notes

Select this model when eight transceiver channels are sufficient for the application, as higher-density variants like the EP1SGX40 offer more resources. Consider the -5, -6, or -7 speed grades based on maximum clock frequency requirements. Verify vertical migration compatibility if upgrading within the same package family.

Part Context

This component belongs to the Stratix GX family, which combines high-performance logic arrays with embedded high-speed serial transceivers. It utilizes the Stratix architecture and is designed for applications requiring significant bandwidth and low power consumption compared to previous generations.

Replacement Considerations

Vertical migration within the 672-pin FineLine BGA package allows substitution with EP1SGX10C/D or EP1SGX25C/F devices, provided pin assignments for I/O and power remain compatible. Cross-referencing device pin-outs is necessary to ensure functional equivalence during migration.
