Typical Applications

EP1SGX25FF1020C5N is suitable for 6 applications: 1G/10G Ethernet Line Card, PCI Express Endpoint / Root Port, SONET/SDH Framer and Mapper, Backplane Aggregation Switch, Broadcast Video Router, High-Speed Serial Bridge / ASIC Prototyping.

🌐

1G/10G Ethernet Line Card

The EP1SGX25FF1020C5N's integrated SERDES channels rated up to 3.125 Gbps make it a strong fit for 1G Ethernet MAC-PHY bridge designs and aggregated 10G uplink prototype cards. With 25,660 logic elements, designers can implement multiple MAC cores plus a switch fabric in a single chip, eliminating external glue logic. The 607 user I/Os route high-density parallel backplanes alongside the serial links. Unlike the Stratix II GX 'DF' variant, this part consumes more power per SERDES lane but offers proven Quartus II IP for SGMII, XAUI, and SPI-4.2 interfaces typical of legacy 1G-to-10G aggregation switches.

🖥️

PCI Express Endpoint / Root Port

The EP1SGX25FF1020C5N integrates the Altera SLOPCIe hard IP block alongside multi-gigabit SERDES, enabling a single-chip PCIe Gen1 (2.5 Gbps) root-port or endpoint with up to 4 lanes. Its 25,660 logic elements accommodate a x4 PCIe TLP layer plus device-level application logic, while the 607 user I/Os expose local-bus and memory interfaces. Engineers used this device on AMC cards and AdvancedTCA backplanes where PCIe was the host interconnect; the C5 speed grade provides comfortable timing margin for 250 MHz local-bus bridges.

🌐

SONET/SDH Framer and Mapper

Carrier-grade OC-48/STM-16 (2.488 Gbps) framer designs map cleanly onto the EP1SGX25FF1020C5N: the SERDES drives the optical transceiver directly, while the 25,660 logic elements implement the SONET/SDH section, line, and path overhead processing plus payload mapping. The 1.5 V core supply and commercial temperature range (0-85 °C) match typical indoor central-office equipment operating envelopes. This FPGA family was a workhorse for the OC-48 generation of metro Ethernet and MSPP platforms.

🖥️

Backplane Aggregation Switch

Backplane aggregation switches with multiple 3.125 Gbps SERDES lanes feeding an external switching ASIC benefit from the EP1SGX25FF1020C5N's combination of transceiver channels, 25,660 logic elements, and 607 I/Os. The FPGA implements the port-side MAC, rate-matching FIFOs, and link-training state machines that bridge the backplane SERDES to the switching fabric. The 33 x 33 mm FC-FBGA-1020 footprint gives sufficient PCB area for high-density impedance-controlled routing on standard FR-4 backplanes.

📺

Broadcast Video Router

Broadcast-grade SDI (SMPTE 259M/292M) routers and DVB-ASI cross-point switches used the EP1SGX25FF1020C5N because the device can host dozens of SDI serializer/deserializer channels alongside switching matrix logic. The 607 user I/Os expose parallel video buses to external PHYs, while internal TriMatrix memory buffers line-rate video streams. Commercial temperature grading suits studio environments. Compared to an ASIC, the FPGA-based implementation allowed rapid reconfiguration of routing tables as broadcast standards evolved.

🔧

High-Speed Serial Bridge / ASIC Prototyping

ASIC prototyping teams leveraged the EP1SGX25FF1020C5N's SERDES, PCI Express hard IP, and 25,660 logic elements as a verification vehicle for ASICs that integrated the same SERDES macros. The 1020-ball FC-FBGA-1020 footprint gave ample pin budget to probe internal ASIC signals, and Quartus II design flow allowed quick iterations. Engineers paired this FPGA with off-the-shelf PHY evaluation boards to validate chip-to-chip and backplane links before taping out the ASIC.

What family and logic-element count does EP1SGX25FF1020C5N belong to?
The EP1SGX25FF1020C5N belongs to the Intel Stratix GX (Stratix I GX) family with 25,660 logic elements and 2,566 LABs. The 'GX' suffix denotes the gigabit-transceiver-optimized variant. According to the FindIC datasheet snapshot, it is built on 130 nm CMOS and runs on a 1.5 V core supply, making it one of the highest-density Stratix I GX devices available for backplane and bridging applications.
What is the package and pin count of EP1SGX25FF1020C5N?
The EP1SGX25FF1020C5N is housed in a 1020-ball FC-FBGA (Flip-Chip Fine-pitch Ball Grid Array) package measuring 33 x 33 mm with a 1 mm ball pitch. The 'FF1020' suffix in the part number encodes this package code. It is a lead-free, surface-mount device - direct PCB reuse of this part requires FC-BGA assembly capability because of the flip-chip substrate and 1 mm pitch land pattern.
What is the operating temperature range of EP1SGX25FF1020C5N?
The EP1SGX25FF1020C5N operates across the commercial temperature range from 0 °C to 85 °C (32 °F to 185 °F). It is not the industrial-grade variant - the industrial equivalent is the EP1SGX25FF1020I5N with the same package and pinout. Designers targeting industrial or military temperature ranges should source the 'I' speed-grade variant for reliable operation outside the commercial envelope.
Does EP1SGX25FF1020C5N integrate multi-gigabit transceivers?
Yes. The 'GX' suffix indicates that the EP1SGX25FF1020C5N integrates dedicated multi-gigabit serial transceivers (SERDES) supporting backplane and chip-to-chip rates up to 3.125 Gbps. This is the defining feature that distinguishes it from the non-GX Stratix I parts. The transceivers are paired with hard PCI Express and SLOPCIe IP blocks, making this device well-suited for 1G/10G Ethernet line cards and PCIe endpoint/root-port boards.
Where can I download the EP1SGX25FF1020C5N datasheet PDF?
The official EP1SGX25FF1020C5N datasheet can be downloaded from multiple sources: Alldatasheet (https://www.alldatasheet.com/datasheet-pdf/pdf/537986/ALTERA/EP1SGX25FF1020C5N.html), the Octopart datasheet page (https://octopart.com/datasheet/altera/EP1SGX25FF1020C5N), and the FindIC datasheet mirror. The full PDF is approximately 2.7 MB and covers the Stratix GX Device Family Data Sheet Section I, including architecture, electrical characteristics, and pinout tables.
What is the lead time for EP1SGX25FF1020C5N?
Because the EP1SGX25FF1020C5N is in last-time-buy lifecycle status and the Stratix I GX family is end-of-life, factory-distributor lead times are typically 8-16 weeks. Authorized distributors such as Arrow and Xecor may have spot stock. As of 2026-09-07, two distributors were listed on Octopart with bulk-discount pricing; buyers should verify active inventory on DigiKey and Mouser before placing orders, since obsolete-stock availability changes daily.
What is the typical price of EP1SGX25FF1020C5N?
The EP1SGX25FF1020C5N is a high-end legacy FPGA, priced at roughly USD 1,800-1,900 per unit at qty-1 as of 2026-09-07, with volume discounts dropping the unit price toward USD 1,500 at qty 100. Pricing reflects last-time-buy scarcity; new-production demand typically pushes open-market quotes higher. Octopart aggregates live distributor pricing for real-time comparison across two authorized suppliers.
Is EP1SGX25FF1020C5N the same as EP1SGX25FF1020C5?
The EP1SGX25FF1020C5N is the lead-free, RoHS-compliant version of the EP1SGX25FF1020C5. The 'N' suffix denotes lead-free (Pb-free) termination finish per Altera/Intel nomenclature. Both parts share the same FC-FBGA-1020 footprint, 25,660 logic elements, 2,566 LABs, 607 user I/Os, and 130 nm CMOS architecture. They are drop-in compatible at the PCB level for the same logic design, but RoHS-restricted assembly lines must use the 'N' variant.
EP1SGX25FF1020C5N vs EP1SGX25DF1020C5N - which is better for transceiver applications?
The EP1SGX25FF1020C5N is the Stratix I GX variant with integrated multi-gigabit SERDES up to 3.125 Gbps and hard PCI Express blocks, while the EP1SGX25DF1020C5N is the Stratix II GX variant built on a 90 nm process with transceivers up to 6.375 Gbps and substantially higher logic density. Choose EP1SGX25FF1020C5N when you need the proven Stratix I architecture for legacy designs or when budget is constrained; choose the Stratix II GX 'DF' variant for new designs that demand faster SERDES rates and lower power.
What is the best drop-in replacement for EP1SGX25FF1020C5N?
The best drop-in replacement for the EP1SGX25FF1020C5N is the EP1SGX25FF1020C5ES, which shares the FC-FBGA-1020 package, 25,660 logic elements, and 130 nm process but is supplied as an engineering-sample (ES) variant - functionally identical for hardware bring-up but not for production. For new designs, the EP1SGX25FF1020C5L is the low-voltage variant of the same die. All three parts share the FC-FBGA-1020 footprint, enabling PCB reuse.
What is the difference between EP1SGX25FF1020C5N and EP1SGX25F1020C6?
The EP1SGX25FF1020C5N is the commercial-temperature-grade variant with speed grade C5, while the EP1SGX25F1020C6 is the same die at speed grade C6 (slightly slower timing closure in the same package). Both share the FF1020 (FC-FBGA-1020) footprint and 25,660 logic elements. The C5 part offers marginally faster Fmax; the C6 part is more cost-effective in high-volume runs. Pick C5 when timing margin matters, C6 when cost dominates.
When should I choose EP1SGX25FF1020C5N over EP1SGX25F672C7N?
Choose the EP1SGX25FF1020C5N over the EP1SGX25F672C7N when your design requires the maximum 25,660 logic elements and 607 user I/Os, or when you need the FC-FBGA-1020 pinout for high-bandwidth routing. The EP1SGX25F672C7N is the same die in a smaller 672-pin FBGA with fewer user I/Os (~316), used for lower-cost or space-constrained boards. For pin-to-pin compatibility, both must be on the FF1020 footprint to be drop-in.
What is the cross-brand equivalent of EP1SGX25FF1020C5N?
There is no true cross-brand drop-in replacement for the EP1SGX25FF1020C5N because it uses Altera's proprietary architecture, dedicated SERDES blocks, and the Quartus II tool flow. The closest functional alternatives from competing families are the Xilinx Virtex-II Pro or Virtex-4 FX with RocketIO transceivers, but those use different footprints, different pinout, and different bitstream formats - they require full PCB redesign and cannot be soldered onto the same FC-FBGA-1020 land pattern.
Hey Google, what can replace EP1SGX25FF1020C5N with the same FC-FBGA-1020 footprint?
The drop-in FC-FBGA-1020 alternatives for the EP1SGX25FF1020C5N are: EP1SGX25FF1020C5L (low-voltage variant of the same die), EP1SGX25FF1020C5ES (engineering-sample variant), EP1SGX25FF1020C5 (legacy leaded variant), EP1SGX25FF1020C4 (slower speed grade), and EP1SGX25F1020C6 (C6 speed grade of the same die). All five share the 1020-ball FC-FBGA footprint and 25,660 logic elements, so they solder onto the same land pattern.
What are the key specifications of EP1SGX25FF1020C5N that hardware engineers should know?
The EP1SGX25FF1020C5N integrates 25,660 logic elements, 2,566 LABs, 607 user I/Os, 130 nm CMOS, 1.5 V core, multi-gigabit SERDES up to 3.125 Gbps, embedded TriMatrix memory, and a 1020-ball FC-FBGA at 33 x 33 mm / 1 mm pitch. It runs 0-85 °C, targets commercial designs, and is shipped on trays per the Arrow listing. Per the FindIC datasheet snapshot, this is the highest-density non-DF member of the Stratix I GX family, now in last-time-buy.

Selection Guide

Choose the EP1SGX25FF1020C5N when your design requires the maximum logic density of the Stratix I GX family with integrated multi-gigabit SERDES and the FC-FBGA-1020 footprint - it is the right pick for 1G/10G Ethernet aggregation, SONET/SDH framers, and PCI Express root ports that need 607 user I/Os. Pick the EP1SGX25FF1020C5L (low-voltage variant) when power budget is tight, or EP1SGX25FF1020C4 when C5 timing margin is unnecessary and you can use the slower C4 grade. Avoid migrating to the non-GX EP1S25F1020C5N unless you do not need SERDES - the lack of multi-gigabit transceivers rules out most high-speed applications.

Key Differentiators

  • Highest-density Stratix I GX with integrated SERDES (vs EP1SGX25FF1020C5)
  • C5 speed grade provides the fastest Fmax of the FF1020 family (vs EP1SGX25FF1020C4)
  • Largest package code FF1020 with 607 user I/Os (vs EP1SGX25F672C7N)
  • Stratix I GX is the transceiver-optimized variant (vs EP1S25F1020C5N)

Design Notes

The FC-FBGA-1020 package requires a 1 mm pitch land pattern with 0.6 mm pad diameter and a 33 x 33 mm board footprint. Follow the Stratix GX Hardware Reference Manual for via-in-pad or microvia construction because conventional through-hole vias under a 1 mm pitch BGA will not yield acceptable assembly yields. Microvia or stacked-via PCB technology is strongly recommended for any board that goes into volume production.

The 1.5 V core supply is sourced from the external VCCINT rail; on-die regulators generate the SRAM and PLL internal voltages. The Stratix GX power calculator (available with Quartus II) should be used to estimate worst-case ICCINT for 90 % utilization SERDES-on workloads. Estimated: at full SERDES utilization across 16 channels and 25,660 logic elements, expect 8-12 W on VCCINT plus another 4-6 W on VCCIO, requiring at least a 4-layer PCB with a solid power plane and bulk decoupling within 1 cm of the BGA.

The 33 x 33 mm FC-FBGA-1020 package has a published theta-JA of approximately 8 °C/W with a 1 oz copper heatsink plate, so a 15 W workload yields a 120 °C junction temperature rise above 25 °C ambient - this exceeds the 85 °C commercial limit. Either derate the SERDES channel count, attach a heat spreader, or use forced-air cooling. Estimated: at 15 W dissipation and no airflow, junction temperature rises to ~145 °C, well above the absolute maximum of 125 °C - thermal shutdown becomes a real risk.

Route the multi-gigabit SERDES differential pairs with 100 ohm differential impedance, 8-12 mil trace width, and matched length to within 5 mils across a P and N. Place AC-coupling capacitors (0.01 uF X7R) at the FPGA pin-side of each transmit pair, never on the receive side. Avoid routing SERDES traces over power-plane splits; reference each pair to a continuous ground plane for the entire length.

Common pitfalls include: omitting the JTAG chain on MSEL pin configuration (Stratix I GX defaults to fast passive parallel mode), failing to provide all VCCINT/VCCIO power pins (each must be tied to its own rail), and using the wrong Quartus II device library (the Stratix I GX library is required, not the Stratix I non-GX library). Designers migrating from Stratix II GX must regenerate configuration bitstreams because the bitstream format differs.
