Typical Applications

EP1SGX40GF1020I5N is suitable for 6 applications: Multi-Gigabit Serial Backplane Routing, SONET/SDH and OTN Line Cards, PCI Express Endpoint / Root Complex, Broadcast Video Router / Switcher, High-Speed Test and Measurement Equipment, Serial RapidIO / Fibre Channel Aggregation.

🌐

Multi-Gigabit Serial Backplane Routing

EP1SGX40GF1020I5N is purpose-built for serial backplane routing in central-office and data-center switches, with 20 CDR-based transceiver channels at up to 3.1875 Gbps each and 41,250 logic elements for switch-fabric arbitration. The on-chip rate matcher complies with IEEE 802.3 clause 36 for Gigabit Ethernet idle insertion/removal, eliminating external PHY chips. Compared to a discrete SERDES-plus-FPGA two-chip solution, EP1SGX40GF1020I5N reduces PCB area by roughly 40% and lowers bill-of-materials cost while simplifying signal-integrity closure.

🌐

SONET/SDH and OTN Line Cards

EP1SGX40GF1020I5N supports OC-48/STM-16 (2.488 Gbps) and OTU1 (2.666 Gbps) line-card data rates directly through its on-chip transceivers, with the 41,250-LE fabric handling framer, mapper, and overhead-processing functions. The embedded CDR removes the need for external clock-recovery PLLs, simplifying the BOM and shortening design cycles. Designers targeting OC-192/STM-64 (10 Gbps) should migrate to Stratix II GX or later, because EP1SGX40 tops out at 3.1875 Gbps per lane.

🖥️

PCI Express Endpoint / Root Complex

EP1SGX40GF1020I5N implements the Physical Media Attachment (PMA) and Physical Coding Sublayer (PCS) of PCI Express 1.0a endpoints through its built-in 2.5 Gbps transceivers, while the 41,250-LE fabric hosts the Transaction Layer and Data Link Layer. Designers can build x4 or x8 PCIe endpoints in a single chip without external PHY silicon. For PCIe Gen2 (5 Gbps) and Gen3 (8 Gbps), migrate to Stratix IV GX or Stratix 10, as EP1SGX40's maximum 3.1875 Gbps serial rate falls short of those speeds.

📺

Broadcast Video Router / Switcher

EP1SGX40GF1020I5N's combination of 20 serial channels and 41,250 logic elements suits uncompressed HD-SDI (1.485 Gbps) and 3G-SDI (2.97 Gbps) routing matrices in broadcast studios. The on-chip transceivers meet the SMPTE 424M/425M jitter tolerance while the fabric handles crosspoint switching, audio embedding, and ancillary data processing. Compared with a discrete crosspoint switch plus glue logic, EP1SGX40GF1020I5N enables a single-chip router with reduced power and board area.

🔧

High-Speed Test and Measurement Equipment

EP1SGX40GF1020I5N's 20 CDR-based channels and high logic density suit protocol analyzers, BERT (bit-error-rate tester) platforms, and logic-analyzer acquisition cards that must capture multiple gigabit links simultaneously. The fabric implements pattern generation, error counting, and trigger logic while the transceivers deliver the physical interface. Designers value the 1 mm-pitch FC-FBGA for its accessible breakout to high-density test fixtures.

🏭

Serial RapidIO / Fibre Channel Aggregation

EP1SGX40GF1020I5N's 3.1875 Gbps transceivers handle 1x/4x Serial RapidIO (1.25, 2.5, 3.125 Gbps) and 1G/2G Fibre Channel (1.0625, 2.125 Gbps) aggregation nodes used in wireless base stations and storage routers. The 41,250-LE fabric implements protocol bridging, packet buffering, and congestion management without external memory controllers. Industrial and military programs with long lifecycle requirements continue to qualify EP1SGX40GF1020I5N despite its obsolete manufacturer status.

What is the logic density of EP1SGX40GF1020I5N?
The EP1SGX40GF1020I5N contains 41,250 logic elements organized into 4,125 configurable logic blocks (CLBs). According to the Altera Stratix GX Device Family datasheet, this places the device in the upper-mid density tier of the Stratix GX family, suitable for multi-gigabit bridging designs that combine protocol logic with parallel processing.
How many high-speed serial transceiver channels does EP1SGX40GF1020I5N have?
The EP1SGX40GF1020I5N integrates 20 CDR-based high-speed serial transceiver channels supporting 500 Mbps to 3.1875 Gbps per channel, for up to 127.5 Gbps of aggregate full-duplex bandwidth. The transceivers perform clock data recovery on-chip, eliminating external PHY devices for protocols such as Gigabit Ethernet, RapidIO, and PCI Express.
What is the core supply voltage of EP1SGX40GF1020I5N?
The EP1SGX40GF1020I5N operates from a 1.5 V core supply with a permitted range of 1.425 V to 1.575 V, per the Stratix GX handbook. I/O banks (VCCIO) typically require separate 1.5 V, 1.8 V, 2.5 V, or 3.3 V rails depending on the standard being interfaced.
What package does EP1SGX40GF1020I5N use?
The EP1SGX40GF1020I5N is housed in a 1020-ball FineLine BGA (FC-FBGA) measuring 33 x 33 mm with 1 mm ball pitch. This large BGA footprint supports the combination of 20 serial channels plus 600+ general-purpose I/Os needed for parallel memory and control interfaces.
Is EP1SGX40GF1020I5N still in production?
The EP1SGX40GF1020I5N is classified obsolete by Altera/Intel - the Stratix GX family has been superseded by Stratix II GX, Stratix IV GX, and ultimately Stratix 10. New designs should target current-generation Altera/Intel FPGA families; remaining stock is available only through distributors and the secondary market.
What is the difference between EP1SGX40GF1020I5N and EP1SGX40GF1020I5?
Both parts share the same 1020-ball FC-FBGA package and 41,250-LE Stratix GX silicon; the suffix after the speed grade typically denotes shipping media and quality grade. The 'N' suffix on EP1SGX40GF1020I5N generally indicates lead-free / Pb-free termination versus the standard EP1SGX40GF1020I5 variant - check the lot-specific datasheet revision for the exact distinction.
Where to buy EP1SGX40GF1020I5N online?
EP1SGX40GF1020I5N is available through secondary-market distributors including Jotrin, Vyrian, Partstack, and Microchip USA, as of 2026-09-07. Because the part is obsolete at the manufacturer, expect limited stock, longer lead times (often 8-16 weeks), and significantly higher unit pricing than original OEM quotes.
What is the price of EP1SGX40GF1020I5N?
As of 2026-09-07, EP1SGX40GF1020I5N is listed in the $140-$245 range across secondary distributors, depending on quantity and traceability documentation. Pricing has trended upward as Stratix GX inventory depletes; authenticated, traceable lots command a premium over pulled-and-resold stock.
What is the lead time for EP1SGX40GF1020I5N?
Lead time for EP1SGX40GF1020I5N typically ranges from 6 to 16 weeks through secondary-market distributors, as of 2026-09-07. Variability is driven by remaining factory stock and ongoing demand from long-lifecycle aerospace and industrial programs. Requesting a quote from multiple distributors simultaneously is recommended.
EP1SGX40GF1020I5N vs EP1SGX25FF1020I5N - which is better for a multi-gigabit bridge?
EP1SGX40GF1020I5N has higher logic density (41,250 LEs vs 25,660 LEs in EP1SGX25FF1020I5N) and more serial channels, making it the better choice for designs needing 16-20 serial links plus large protocol-processing logic. EP1SGX25FF1020I5N is preferable for cost-sensitive designs using 8 channels or fewer where lower logic density suffices.
When should I choose EP1SGX40GF1020I5N over a Stratix II GX device?
Choose EP1SGX40GF1020I5N only when re-spinning a legacy Stratix GX design or maintaining a field-deployed product with an existing Stratix GX firmware base. For new designs, Stratix II GX and later devices offer higher density, lower power, and active lifecycle support - new designs should not start on the original Stratix GX family.
What is the best drop-in replacement for EP1SGX40GF1020I5N?
The closest pin-compatible drop-in replacements are other EP1SGX40 speed-grade variants in the same 1020-ball FC-FBGA package, such as EP1SGX40GF1020C6, EP1SGX40GF1020C7, and EP1SGX40GF1020C8, all listed on the XAIPART Site MPN list. These variants differ only in speed grade and temperature range; the silicon and pinout are identical.
Can EP1SGX40DF1020I5N replace EP1SGX40GF1020I5N on the same PCB?
Yes - EP1SGX40DF1020I5N shares the same 1020-ball FC-FBGA package and 41,250-LE silicon, so it is pin-to-pin compatible with EP1SGX40GF1020I5N. The 'D' suffix denotes a different transceiver configuration and lower serial bandwidth; verify that your design does not exceed the EP1SGX40D channel count before substituting.

Selection Guide

Choose EP1SGX40GF1020I5N when you need the full 20-channel 3.1875 Gbps transceiver complement with industrial temperature qualification and lead-free finish, in a 1020-ball FC-FBGA footprint. It is the right part for new or maintenance designs targeting OC-48/STM-16 line cards, PCI Express 1.0a endpoints, Gigabit Ethernet backplanes, and 3G-SDI routers. For cost-reduced designs needing fewer channels, EP1SGX40DF1020I5N (D-variant) shares the same package. For designs without serial links, EP1SGX40CF1020I5 saves power and cost. For new designs in 2026, however, prefer Stratix II GX, Stratix IV GX, or current Stratix 10 devices to avoid the obsolete-status supply-chain risk of the original Stratix GX family.

Key Differentiators

  • Highest-density Stratix GX variant with full 20-channel transceiver complement (vs EP1SGX40CF1020I5)
  • Industrial temperature grade with lead-free termination (vs EP1SGX40GF1020I5)
  • Faster speed grade than -7 and -8 silicon (vs EP1SGX40GF1020C7)

Design Notes

Estimated: Stratix GX EP1SGX40 with 20 active 3.1875 Gbps transceivers and ~70% logic utilization dissipates approximately 8-12 W from the 1.5 V core rail alone. Provide at least 6 low-impedance 0.1 uF + 10 uF ceramic decoupling pairs within 5 mm of the BGA balls, plus bulk polymer capacitors on each VCCIO bank. Sequence VCCINT before VCCIO per Altera's power-up guidelines to avoid I/O driver latch-up; an integrated supervisory IC such as the TPS3808 is recommended for the POR signal.

Estimated: With theta-JA around 12 C/W for the 33 x 33 mm FC-FBGA on a 12-layer JEDEC test board, 10 W dissipation produces roughly 120 C junction temperature rise above ambient - too high for commercial 85 C operation. Use a heatsink with thermal interface material or design a 6+ layer PCB with continuous inner-plane copper beneath the BGA footprint to reduce theta-JA below 8 C/W. Always validate thermal design with a real prototype before committing to enclosure thermal budgets.

The 1020-ball FC-FBGA at 1 mm pitch requires microvia (laser-drilled) stack-up fabrication. Use 8-12 layer PCB construction with sequential lamination to build the 0.1 mm via-on-pad structures. Maintain a continuous reference plane (GND) on layer 2 directly under the BGA to control impedance of the high-speed transceiver traces; route serial channels with 100 ohm differential impedance and skew matching to within 5 ps. Xilinx/Altera reference design layout files (available on the Altera Wiki archive) provide proven routing examples.

Do not confuse EP1SGX40G (suffix-less, the base family) with the package-suffixed 'GF1020I5N' ordering code - the latter includes speed grade, package, and lead-free information. Also verify your Quartus II version supports the specific silicon revision; Quartus 9.0 and later is recommended for stable synthesis of the 20-channel transceiver blocks. Always generate the Stratix GX PCB symbol from the Quartus pin-out file rather than hand-drafting it - mismatched GND/VCC pin assignments are a common bring-up failure.
