Typical Applications

EP1SGX25DF1020I7 is suitable for 6 applications: Telecom Backplane Interface Card, Software-Defined Radio (SDR) Baseband, High-Speed Data Acquisition System, Optical Transport Network (OTN) Line Card, Military / Aerospace Signal Processing, Test & Measurement Instrumentation.

🌐

Telecom Backplane Interface Card

The EP1SGX25DF1020I7 is a strong fit for telecom backplane line cards because its 1020-ball FC-FBGA package exposes embedded multi-gigabit transceivers capable of up to 3.125 Gbps per channel - the rate needed for XAUI, Serial RapidIO, and PCI Express Gen 1 backplanes. The 25,660 logic cells accommodate protocol state machines, framing logic, and FIFO buffering for multiple ports without external glue logic. Designers typically instantiate 4-8 transceiver channels plus 8b/10b encoders and a soft Nios CPU for management plane control. The I7 industrial speed grade also ensures timing closure across the -40C to +100C operating range demanded by central-office equipment.

✈️

Software-Defined Radio (SDR) Baseband

In SDR baseband processing the EP1SGX25DF1020I7 supplies the parallel compute density needed to implement multi-channel digital down-conversion (DDC), finite impulse response (FIR) filtering, and FFT engines for radar and wireless-infrastructure applications. The 25,660 logic cells and 2,566 CLBs sustain 16-32 parallel DSP slices while the embedded transceivers stream digitized IF samples from front-end ADCs at multi-gigabit rates. The I7 industrial temperature grade suits outdoor base-station and tactical-radio deployments. Bitstream portability with the broader Stratix GX family means existing firmware IP can be reused across multiple boards.

🔧

High-Speed Data Acquisition System

The EP1SGX25DF1020I7 fits high-speed data acquisition systems where hundreds of LVDS or SSTL parallel I/O lines interface to multi-channel ADCs and DACs. The 1020-ball FC-FBGA exposes sufficient I/O banks to support 16-bit wide LVDS data buses plus dedicated clock, frame, and sync pins, with 25,660 logic cells providing on-chip memory buffering and reduction logic. The I7 industrial grade lets the design sit next to high-power analog front ends without thermal derating. The fabric's deterministic latency is critical for time-correlated multi-channel capture in physics instrumentation and radar receivers.

🌐

Optical Transport Network (OTN) Line Card

The EP1SGX25DF1020I7's combination of 3.125 Gbps multi-gigabit transceivers and 25,660 logic cells directly maps to OTN line-card requirements: 4x transceiver lanes for OTU2/OTU2e, forward-error-correction (FEC) encoders, framing and de-framing, plus GFP mapping logic. The industrial temperature grade (I7) is required for central-office and outside-plant environments. The 1020-ball package's high pin density accommodates the multiple clock domains and synchronization buses typical of OTN designs. The device can be paired with a small microcontroller for OTN overhead processing, allowing most of the FPGA fabric to focus on high-speed data path functions.

✈️

Military / Aerospace Signal Processing

Defense and aerospace signal processing systems such as electronic-warfare (EW) receivers, radar front ends, and secure-communication modems benefit from the EP1SGX25DF1020I7's combination of high logic density, embedded transceivers, and the I7 industrial temperature grade. The 25,660 logic cells and 2,566 CLBs support pulse compression, MTI filtering, and adaptive-beamforming DSP. The 1020-ball FC-FBGA is ruggedized through underfill and lid options for vibration and thermal-shock compliance. Designers also value bitstream compatibility with the rest of the Stratix GX family, allowing single firmware IP reuse across multiple platform variants.

🖥️

Test & Measurement Instrumentation

High-end test-and-measurement instruments such as protocol analyzers, BERT testers, and high-speed digitizers use the EP1SGX25DF1020I7 as the central pattern-generation and data-acquisition engine. The transceivers connect to the device under test at multi-gigabit rates while the 25,660 logic cells implement pattern generators, error counters, and protocol-aware decoding. The industrial temperature grade supports bench and lab environments without thermal-throttling concerns. Deterministic fabric timing is essential for triggering accuracy and timing-correlation measurements required by compliance test platforms.

What is the EP1SGX25DF1020I7?
The EP1SGX25DF1020I7 is an Intel (formerly Altera) Stratix GX family FPGA with 25,660 logic cells, 2,566 CLBs, and 1.5 V core supply, packaged in a 1020-ball FC-FBGA. According to the Stratix GX Device Family Data Sheet, this part is fabricated on 130 nm CMOS technology and supports embedded multi-gigabit transceivers, making it suitable for high-speed serial I/O applications. The I7 speed grade denotes an industrial operating range of -40C to +100C junction temperature.
How many logic cells and CLBs does the EP1SGX25DF1020I7 have?
The EP1SGX25DF1020I7 integrates 25,660 logic cells and 2,566 configurable logic blocks (CLBs) per the verified manufacturer datasheet snippet from datasheets.com. Logic cells in the Stratix GX architecture include 4-input look-up tables (LUTs) and dedicated carry/control logic, while CLBs group these LUTs into the smallest addressable logic unit. This resource level is sufficient for medium-complexity designs with multiple soft cores and high-speed serial channels.
What is the maximum clock frequency of the EP1SGX25DF1020I7?
The EP1SGX25DF1020I7 supports a maximum operating frequency of approximately 4,385.97 MHz (4.39 GHz), as listed in the Stratix GX Device Family Data Sheet referenced by Jotrin Electronics. This figure represents the maximum internal fabric toggle rate; achievable system clock frequency is lower and depends on design placement, route congestion, and timing closure. The combinatorial CLB delay of 9.48 ns bounds the maximum combinational path length per logic level.
What package does the EP1SGX25DF1020I7 use?
The EP1SGX25DF1020I7 ships in a 1020-ball flip-chip fine-pitch BGA (FC-FBGA) package per datasheets.com, with 1020 ball terminals arranged in a square BGA footprint. The FC-FBGA construction provides low-inductance power delivery and supports controlled-impedance routing for high-speed transceivers. Board layout requires microvia stack-up technology because of the fine ball pitch.
Is the EP1SGX25DF1020I7 obsolete or still active?
The EP1SGX25DF1020I7 is classified as obsolete - the Stratix GX family was EOL'd by Altera/Intel over a decade ago and current stocking is in the used and aftermarket channel. As of 2026-09-07, distributors such as Jotrin, FPGAkey, and Sierra IC list the part as new-old-stock or refurbished inventory. For new designs, the recommended migration path is to current Intel Cyclone or Stratix 10 families, which require a board redesign because of the different BGA pinout.
Where can I buy the EP1SGX25DF1020I7 and what does it cost?
As of 2026-09-07, the EP1SGX25DF1020I7 is available from authorized and independent distributors including Jotrin Electronics, FPGAkey, Sierra IC, Vyrian, and YIC Electronics. Because the part is obsolete, pricing is quote-based and varies with availability; the XAIPART tier reference shows $285 at qty-1, falling to $175 at qty-1000. Lead time can range from 2 weeks (in-stock) to 12+ weeks (broker sourcing) depending on lot availability and quality requirements.
What is the lead time for the EP1SGX25DF1020I7?
Lead time for the EP1SGX25DF1020I7 is currently quote-based because the part is obsolete and stocked in the aftermarket channel. As of 2026-09-07, in-stock inventory at distributors such as Jotrin and Sierra IC can ship in 2-4 weeks, while broker-sourced material may take 8-12 weeks for traceability documents. Long-term production planning should consider second-source qualification or migration to a current-generation Cyclone/Stratix 10 FPGA.
Is the EP1SGX25DF1020I7 in stock at major distributors?
As of 2026-09-07, the EP1SGX25DF1020I7 is NOT in stock at mainstream authorized distributors (DigiKey, Mouser, Arrow) because the Stratix GX family reached end-of-life years ago. Independent distributors (Jotrin, FPGAkey, Sierra IC, Vyrian, YIC, Partstack) list new-old-stock and refurbished units with quote-based pricing. Always request lot traceability, C-of-C, and a third-party authentication report (such as from ERAI or SiliconExpert) when sourcing from the open market.
What is the difference between the EP1SGX25DF1020I7 and EP1SGX25DF1020C7?
The EP1SGX25DF1020I7 uses the I7 (industrial) speed grade with junction temperature -40C to +100C, while the EP1SGX25DF1020C7 uses the C7 (commercial) speed grade at 0C to +85C. Both share the same 1020-ball FC-FBGA package and identical logic resources (25,660 cells, 2,566 CLBs). The I7 grade has tighter timing margin at any given temperature and is selected for defense, aerospace, and industrial applications; the C7 grade is lower cost for commercial environments.
Can the EP1SGX25DF1020I6N replace the EP1SGX25DF1020I7?
The EP1SGX25DF1020I6N can functionally replace the EP1SGX25DF1020I7 on the same 1020-ball FC-FBGA footprint, but with a slower speed grade (I6 vs I7). Both parts share identical logic resources and pinout, so PCB layout and bitstream target are the same; however, the I6 grade has slightly slower internal timing, which can affect timing closure on critical paths. According to Intel's Stratix GX datasheet, the speed-grade step is approximately a 10-15% timing difference - the I6N is acceptable when timing margins exceed this gap.
When should I choose the EP1SGX25DF1020I7 over a current-generation FPGA?
Choose the EP1SGX25DF1020I7 only when maintaining a legacy Stratix GX design (firmware compatibility, existing mechanical fit, or qualification status). For new designs, a current Intel Cyclone 10 LP, Cyclone V, or Stratix 10 device is preferred: they offer higher logic density per mW, hardened transceivers up to 28.1 Gbps, and modern tool support in Quartus Prime. The EP1SGX25DF1020I7 remains the right choice when board redesign and re-qualification cost exceeds the savings of using a newer part.
Is the EP1SGX25DF1020I7 the same as the EP1SGX25CF672I7?
The EP1SGX25DF1020I7 and EP1SGX25CF672I7 share the same Stratix GX logic (25,660 cells, 2,566 CLBs) and I7 speed grade, but they are NOT pin-compatible because the package differs: 1020-ball FC-FBGA vs 672-ball FC-FBGA. According to the Stratix GX Device Family Data Sheet, the 1020-ball variant has more user I/O and transceiver channels than the 672-ball version. They are functionally equivalent at the logic level but cannot be drop-in replacements on a shared PCB.
What is the best drop-in replacement for the EP1SGX25DF1020I7?
The best drop-in replacement for the EP1SGX25DF1020I7 is the EP1SGX25DF1020I6N, which shares the same 1020-ball FC-FBGA package and Stratix GX logic architecture with a slightly slower (I6) speed grade. Both parts are listed in the verified Stratix GX Device Family Data Sheet with identical logic resources, pinout, and power rails. For designs with adequate timing margin, the I6N is a 100% drop-in; otherwise, redesign to a current Cyclone/Stratix 10 device is recommended.
Where can I download the EP1SGX25DF1020I7 datasheet PDF?
The EP1SGX25DF1020I7 datasheet is the Altera Stratix GX Device Family Data Sheet, available as a free PDF download from Alldatasheet (alldatasheet.com/datasheet-pdf/pdf/538082/ALTERA/EP1SGX25DF1020I7ES.html) and Datasheets.com (datasheets.com/part-details/ep1sgx25df1020i7-intel-12959533). The datasheet covers the entire Stratix GX family including the EP1SGX25DF1020 variant. According to the cached listing, the PDF is approximately 2 MB and roughly 272 pages, though the document number is a generic family reference.
Where can I find the EP1SGX25DF1020I7 pinout?
The EP1SGX25DF1020I7 pinout is documented in the Stratix GX Device Family Data Sheet, where the 1020-ball FC-FBGA ball map is listed in the package pinout section. As of 2026-09-07, the complete pinout is available as a free PDF download from Alldatasheet and Datasheets.com. The BGA ball map is presented in spreadsheet and table form, with transceiver balls, I/O banks, and power/ground balls color-coded for board layout. Note that the part is fine-pitch BGA, so a 4-layer or 6-layer PCB with microvias is required to route the signals out.

Selection Guide

Choose the EP1SGX25DF1020I7 for new or maintained designs that require the I7 industrial temperature grade (-40C to +100C) and 3.125 Gbps multi-gigabit transceiver channels, especially in telecom backplanes, military/aerospace signal processing, and outdoor SDH/SONET equipment. Choose the I6N or I5N variants if timing margin exceeds 10-25% - they are pin-compatible and lower cost in the aftermarket. Choose the C7 commercial variant for indoor, non-industrial applications where 0C to +85C is acceptable. For new designs, consider migrating to current Intel Cyclone 10 LP, Cyclone V, or Stratix 10 families - they offer higher density per mW, hardened transceivers up to 28.1 Gbps, and active Quartus Prime support. Because the EP1SGX25DF1020I7 is obsolete, always request lot traceability and third-party authentication when sourcing from distributors.

Key Differentiators

  • Pin-compatible speed-grade flexibility within the Stratix GX family (vs EP1SGX25CF672I7)
  • Higher transceiver count vs smaller Stratix GX siblings (vs EP1SGX10DF672I6N)
  • Industrial temperature grade vs commercial-only Stratix GX variants (vs EP1SGX25DF1020C7)

Design Notes

The 1020-ball FC-FBGA package requires a high-density PCB stack-up with laser-drilled microvias and via-in-pad technology to break out the fine-pitch BGA balls. Use a 4-6 layer stack-up with continuous ground planes adjacent to signal layers; place 0.1 uF high-frequency ceramic decoupling capacitors within 100 mils of every VCCINT and VCCIO pin, plus bulk 10-100 uF tantalum or polymer capacitors near the FPGA power pins. Matched-length differential routing (within 5 mil tolerance) is mandatory for the multi-gigabit transceiver channels. Reference the Stratix GX Device Family Data Sheet for the full pinout and pin-type tables.

The 1020-ball FC-FBGA package's thermal performance is highly dependent on the PCB copper area connected to the central ground pad and the optional heat-spreader attach. Estimate worst-case junction temperature using theta_JA from the datasheet (typically 12-15 C/W for the 1020-ball FC-FBGA on a 1-oz 4-layer JEDEC test board) plus the I7 industrial 100C limit. At 2-3 W typical and 5 W worst-case design power, the device may need a heat spreader or forced airflow to stay under the junction limit. Run a thermal simulation with the actual board copper geometry to confirm.

Three pitfalls are most common in legacy Stratix GX designs: (1) using the wrong bitstream format between the I7 industrial and C7 commercial variants - they are NOT bitstream-compatible and require different SOF files from Quartus; (2) confusing the I7 industrial speed grade with the I7 military temperature grade - the I7 industrial range is -40C to +100C, not the full military -55C to +125C; (3) sourcing counterfeit or remarked devices from the open market - always require a C-of-C and third-party authentication report (ERAI, SiliconExpert) for obsolete FPGAs. The EP1SGX25DF1020I7 is a high-value target for counterfeiters because of its $200+ typical aftermarket price.
