Typical Applications
EP1SGX25FF1020C7 is suitable for 6 applications: Multi-Gigabit Serial Bridge Cards, Telecom Backplane Aggregation, Digital Video Broadcast Equipment, High-Speed Instrumentation and Test Equipment, Military and Aerospace Signal Processing, Industrial Imaging and Machine Vision.
Multi-Gigabit Serial Bridge Cards
The EP1SGX25FF1020C7 is well suited for multi-gigabit serial bridge cards because it combines 25,660 logic elements with the Stratix GX family hardened transceivers supporting protocols up to 3.125 Gbps such as PCI Express, Gigabit Ethernet, and Serial RapidIO. Placed on a line card between a host ASIC and backplane, the device performs protocol translation, buffering in its 1,944,576-bit embedded RAM, and clock domain crossing. Its 607 user I/O pins provide ample headroom for parallel side-band signaling, while the FF1020 BGA allows dense board placement. Compared with discrete serializer/deserializer chips plus an FPGA, this part saves board area and simplifies BOM. The trade-off is higher unit cost and the obsolete status requiring long-term inventory planning.
Recommended
Telecom Backplane Aggregation
Telecom backplane aggregation nodes aggregate multiple lower-speed tributary signals into a higher-speed uplink, requiring large logic capacity for protocol mapping and significant transceiver bandwidth. The EP1SGX25FF1020C7 fits this role with 25,660 LEs for protocol state machines, 1,944,576 bits of on-chip RAM for cell/packet buffering, and multiple GX transceivers for tributary links. Placed on an AdvancedTCA or proprietary backplane card, the device terminates incoming serial streams, de-maps framing, and re-multiplexes onto a higher-rate uplink. Designers benefit from Quartus II's timing-driven compilation for deterministic backplane timing closure. The 1020-FBGA footprint demands microvia PCB fabrication, so early PCB vendor engagement is critical.
Recommended
Digital Video Broadcast Equipment
Digital video broadcast (DVB) and professional video routers require high-speed serial I/O for SDI (Serial Digital Interface) at 270 Mbps, 1.485 Gbps, and 2.97 Gbps, combined with logic capacity for audio embedding, ancillary data processing, and format conversion. The EP1SGX25FF1020C7 handles multiple SDI streams simultaneously through its GX transceivers while the 25,660 logic elements implement video processing pipelines. Placed on a video router crosspoint card, it provides 4-8 SDI ports per device with audio de-embedding into embedded RAM. The 607 user I/O pins also support parallel control interfaces and GPIO for module-level housekeeping. This obsolete part remains in long-lifecycle broadcast installations; new designs should consider Cyclone 10 GX or Arria 10 GX.
Recommended
High-Speed Instrumentation and Test Equipment
Test and measurement instruments such as oscilloscopes, logic analyzers, and protocol analyzers require fast data acquisition, large on-chip memory for sample buffering, and high pin counts for parallel test access. The EP1SGX25FF1020C7 supports these roles with 25,660 LEs for trigger logic, 1,944,576-bit RAM for waveform samples, and 607 I/O pins for probe multiplexing. GX transceivers enable high-speed serial data export to host computers. Placed on a digitizer board, the FPGA preprocesses samples and forwards them to a host via serial links, reducing host CPU load. The 1020-FBGA package allows dense channel placement; careful BGA fan-out and matched-length routing are essential for analog signal integrity.
Recommended
Military and Aerospace Signal Processing
Defense and aerospace signal-processing systems such as radar front-ends, electronic warfare subsystems, and satellite communication modems demand high logic capacity for DSP algorithms combined with radiation tolerance or extended temperature operation. The EP1SGX25FF1020C7, in its commercial 0-85 C grade, is suitable for ground-based or sheltered installations, while extended-temperature variants exist in the family. With 25,660 LEs and embedded multiplier blocks, the device implements FFT, digital down-conversion, and matched filtering in real time. The 1020-FBGA package suits ruggedized PCB assemblies with thermal management. Designers in this sector typically maintain multi-year inventory due to the obsolete status and long qualification cycles.
Recommended
Industrial Imaging and Machine Vision
Industrial machine-vision systems require high-bandwidth image acquisition from Camera Link, CoaXPress, or GigE Vision cameras, combined with real-time image processing pipelines. The EP1SGX25FF1020C7 can interface with Camera Link base/medium/full configurations using its transceivers and abundant I/O, and it implements preprocessing functions like Bayer demosaicing, color space conversion, and feature extraction in its 25,660 LEs. The 1,944,576 bits of embedded RAM buffer full image lines on chip. Placed on a frame grabber card, the FPGA transfers processed data over PCIe to the host PC. The 1020-FBGA package supports the multi-layer PCB stackups needed for high-speed camera interfaces, though designers should plan for the obsolete lifecycle.

Key Differentiators
- Fastest Stratix GX speed grade for the 25K LE die (vs EP1SGX25FF1020C6)
- Includes hardened multi-gigabit transceivers (vs EP1S25F1020C7)
- Highest I/O count in the Stratix GX family at this logic capacity (vs EP1SGX10FF672C7)
Design Notes
The 1020-ball FC-FBGA package with 1 mm ball pitch demands microvia or via-in-pad PCB technology. Standard 0.2 mm drilled vias cannot escape the 1 mm pitch reliably. Designers must engage their PCB fabrication vendor early to confirm stackup, microvia aspect ratio, and BGA fan-out routing capability before committing to board layout. Ground and power planes should be solid under the BGA to provide low-impedance return paths for high-speed transceivers.
Estimated: at 25,660 LEs utilization near 70% with typical Stratix GX toggle rates, the core current can exceed several amperes. Designers must provide a low-impedance 1.5 V plane, place bulk decoupling capacitors (typically 220 uF to 470 uF polymer) near the BGA, and add high-frequency ceramic capacitors (10 uF, 1 uF, 0.1 uF) at the package perimeter. Multiple VCCIO banks each require independent decoupling per the manufacturer datasheet. Voltage regulators should be sized with 30-50% headroom above calculated worst-case current to handle inrush during configuration.
Do not assume the EP1SGX25FF1020C7 is still in production - the Stratix GX family is obsolete. New designs should consider Stratix IV GX, Cyclone 10 GX, or Arria 10 GX for active lifecycle support. For maintenance of legacy boards, verify Quartus II software version compatibility (7.2 or later for the Stratix GX family) and secure long-term inventory supply before committing to production schedules. Configuration bitstream security (e.g., AES encryption) should be verified per the Quartus II configuration user guide.
