Typical Applications
EP1AGX35DF780C5N is suitable for 6 applications: PCI Express Endpoint Card, Multi-Port Gigabit Ethernet Aggregation, SDI/HD-SDI Video Processing, Wireless Baseband DSP (Serial RapidIO), Industrial Machine Vision Inspection Systems, Protocol Aggregation Telecom Line Card.
PCI Express Endpoint Card
The EP1AGX35DF780C5N is well-suited to PCI Express Gen1 endpoint applications. The device includes hard PCIe IP supporting x1, x4, and x8 lane configurations through its eight integrated multi-gigabit transceivers, each capable of 2.5 Gbps operation. Compared with soft PCIe implementations in competing FPGAs, the hard PIPE interface reduces fabric utilization by approximately 25-30% and frees DSP blocks for protocol-layer logic. The 33,520 logic elements and 341 dedicated 18x18 multipliers support rich PCIe endpoint stacks plus application logic.
Recommended
Multi-Port Gigabit Ethernet Aggregation
The EP1AGX35DF780C5N supports multi-port Gigabit Ethernet aggregation in telecom line cards. Each of its eight transceivers can drive a 1.25 Gbps SGMII link, giving the device 8-Gigabit Ethernet capacity. The hard Gigabit Ethernet MAC IP blocks in the transceiver companion logic reduce soft-logic footprint by approximately 40% versus software implementations, and the eight PLLs (four with Dynamic Phase Alignment) support precise clock recovery across all ports. Designers can implement VLAN tagging, QoS, and L2 switching in the 33,520 logic elements.
Recommended
SDI/HD-SDI Video Processing
Broadcast SDI and HD-SDI video processing applications benefit from the EP1AGX35DF780C5N's transceiver characteristics and embedded memory. HD-SDI at 1.485 Gbps and 3G-SDI at 2.97 Gbps fit comfortably within the 600 Mbps to 3.125 Gbps transceiver envelope. The 1,348,416 embedded memory bits provide line buffers for deinterlacing and frame-rate conversion, while the 341 dedicated 18x18 multipliers support video scaling and chroma resampling in real time. The industrial temperature range of this device is also well-matched to outdoor broadcast equipment.
Recommended
Wireless Baseband DSP (Serial RapidIO)
Serial RapidIO (SRIO) is widely deployed in wireless baseband DSP fabrics, and the EP1AGX35DF780C5N supports SRIO at 1.25, 2.5, and 3.125 Gbps per lane through its transceiver interface. Its 341 dedicated 18x18 multipliers enable high-performance DSP for LTE and HSPA+ PHY layers, while the eight transceivers provide up to 8 lanes of SRIO connectivity for DSP-FPGA chaining. Designers can implement multi-antenna MIMO processing, channel coding, and FFT/iFFT operations in the device's parallel DSP fabric.
Recommended
Industrial Machine Vision Inspection Systems
High-speed industrial inspection and machine vision systems benefit from the EP1AGX35DF780C5N's combination of transceivers for Camera Link or CoaXPress interfaces and embedded DSP for real-time image processing. The industrial temperature range (-40C to +125C) and reliable 780-BGA packaging allow deployment in harsh factory environments. The 341 dedicated multipliers accelerate convolution, edge detection, and pattern-matching algorithms; the 1,348,416 bits of embedded memory buffer image lines; and the multi-gigabit transceivers receive high-bandwidth sensor data at up to 3.125 Gbps per lane.
Recommended
Protocol Aggregation Telecom Line Card
Telecom line cards aggregating multiple protocols (Ethernet, OTN, SDI, PCIe) can use the EP1AGX35DF780C5N's mixed-protocol transceiver capability to replace multiple ASSPs. Each of the eight multi-gigabit transceivers can be independently configured for a different protocol at 600 Mbps to 3.125 Gbps, allowing flexible per-port aggregation without changing FPGA bitstream hardware. The 33,520 logic elements and eight PLLs (including four with DPA) support OAM, switching, and timing distribution across the aggregated links.

Key Differentiators
- Industrial temperature operation is already integrated (no -Q suffix needed) (vs EP1AGX35CF780C6N)
- Faster internal timing closure (C5 vs C6) for high-Fmax designs (vs EP1AGX35CF780I6N)
- Hard PCIe and GIGE MAC IP blocks free 25-40% of FPGA fabric (vs Xilinx XC6SLX45T (Spartan-6 LXT))
Design Notes
The EP1AGX35DF780C5N in 780-ball FineLine BGA dissipates significant power when all eight transceivers operate at 3.125 Gbps. Estimated: assuming 150 mW per active transceiver plus 1.5 W static logic at full 33,520 LE utilization, total power can exceed 3 W. The FineLine BGA has a typical theta-JA of approximately 18 C/W with 4-layer PCB and 16 thermal vias under the exposed pad; at 3 W dissipation this gives 54 C junction temperature rise. Adequate thermal design with multiple PCB thermal vias and copper pouring is required to maintain the -40C to +125C industrial temperature range.
The 780-ball FineLine BGA requires a 1.0 mm ball pitch with matched-impedance trace routing. Differential transceiver pairs should be length-matched within 5 mil to avoid skew penalties on multi-gigabit links. Maintain continuous reference plane under the BGA and use 4 mil/8 mil trace geometry for 100-ohm differential impedance. The exposed thermal pad (ePad) must be soldered with multiple thermal vias (typically 0.3 mm drill, 1.0 mm pitch grid) for heat dissipation. JTAG and configuration pin pull-ups are required per Altera reference designs.
Designers should be aware that this device is in Last-Time-Buy status as of 2026-09-06 per the Verified Web Data, meaning inventory will shrink rapidly and prices will escalate. New designs should migrate to the Cyclone V GX family (5CGXFC5/7/9) for active production, or the Arria V GX family for higher-end migration. If staying with Arria GX, hedge inventory and finalize a board redesign plan in case supply runs dry before the end-of-life date.
Multi-gigabit transceiver channels require AC-coupled interconnects; place the 100 nF AC coupling capacitors within 100 mil of the transmitter pins. Use differential via structures with matched return paths and avoid right-angle bends. The PLL reference clock must come from a low-jitter source (RMS jitter below 3 ps is typical for 3.125 Gbps links); use a dedicated clock IC rather than FPGA-derived clocks. Pre-emphasis and equalization settings should be configured via the Altera Transceiver Toolkit during board bring-up.
