EP1SGX40GF1020I6N

Overview

The Altera EP1SGX40GF1020I6N is a Stratix GX Field-Programmable Gate Array housed in a 1,020-pin FineLine BGA package. It features 41,250 logic elements and 20 high-speed serial transceiver channels capable of full-duplex operation from 500 Mbps to 3.1875 Gbps. The device includes TriMatrix memory with up to 3,423,744 RAM bits and DSP blocks for signal processing. Built on 1.5-V technology, it supports protocols such as XAUI, Gigabit Ethernet, PCI Express, and SONET/SDH. The -6 speed grade ensures specified timing performance for high-speed backplane and chip-to-chip interfaces.

Feature Summary

• 20 high-speed serial transceiver channels with integrated Clock Data Recovery (CDR) supporting data rates up to 3.1875 Gbps.
• 41,250 Logic Elements (LEs) and up to 3,423,744 bits of embedded TriMatrix memory.
• Support for 8B/10B encoding/decoding, programmable pre-emphasis, equalization, and variable output drive voltage (VOD).
• Compatibility with XAUI, Gigabit Ethernet, PCI Express, Fibre Channel, Serial RapidIO, and SMPTE 292M standards.

Applications

• High-speed backplane interface systems requiring multi-gigabit serial connectivity.
• Chip-to-chip communication links utilizing XAUI or Gigabit Ethernet protocols.
• Communications protocol bridging between different serial standards.
• Test and measurement equipment demanding low-latency signal processing.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's pinout and speed grade documentation. Confirm that the 1,020-pin FineLine BGA package dimensions match the target PCB footprint. Ensure thermal management solutions are adequate for the power consumption profile of the Stratix GX family under maximum load conditions.

Selection Notes

Select this model when 20 transceiver channels and over 40,000 logic elements are required within a single device. Compare against the EP1SGX40D variant if fewer I/O pins are sufficient, noting the difference in pin count and package size. Consider the -6 speed grade for balanced performance and power consumption relative to -5 or -7 grades.

Part Context

This component belongs to the Stratix GX FPGA family, Altera’s second generation combining high-speed serial transceivers with scalable logic arrays. It serves as a bridge between earlier low-density devices and later high-performance families like Stratix IV and Stratix 10, specifically targeting applications needing robust SERDES capabilities at the time of its release.

Replacement Considerations

Vertical migration within the same package allows replacement with other EP1SGX40 variants sharing the 1,020-pin footprint, provided I/O pin compatibility is verified. Cross-family upgrades may require redesign due to architectural differences in transceiver blocks and logic resources.
