Typical Applications

EP1AGX35DF780 is suitable for 6 applications: Telecom Backplane Aggregation, Broadcast Video Routing and SDI Switching, PCI Express Endpoint Cards, High-Speed Data Acquisition Front-Ends, Industrial Protocol Bridging, Wireless Baseband Processing.

🌐

Telecom Backplane Aggregation

The EP1AGX35DF780's 8 channels of 3.125 Gbps transceivers are a direct fit for telecom backplane aggregation cards that consolidate multiple lower-speed tributary links into a higher-speed uplink. Its 33,520 logic elements, 1.34 Mbit embedded RAM, and 341 user I/Os provide ample headroom to implement cross-connect logic, packet buffering, and SERDES adaptation in a single device - eliminating the cost and board area of an external PHY. The hard PCS/PMA also supports protocols like Serial RapidIO and Interlaken natively.

📺

Broadcast Video Routing and SDI Switching

Studio and broadcast video routers need to switch SD-SDI (270 Mbps), HD-SDI (1.485 Gbps), and 3G-SDI (2.97 Gbps) streams between many sources and destinations. The EP1AGX35DF780's transceiver channels handle SDI natively at standard rates, while its 33K logic elements, embedded multipliers, and 1.34 Mbit RAM implement genlocking, audio de-embedding, and matrix-switching fabric. Industrial temperature variants qualify the part for 24/7 broadcast-facility operation where downtime is unacceptable.

🖥️

PCI Express Endpoint Cards

With native 3.125 Gbps transceivers, the EP1AGX35DF780 implements PCIe Gen1 x1/x4 endpoints without external PHY chips, cutting BOM cost and board area. Its 33K logic elements host a soft PCIe IP core plus application payload, while the 1.34 Mbit embedded RAM serves as a transaction buffer for DMA engines. Industrial-grade variants suit ruggedized server cards, industrial PCs, and instrumentation add-in boards where extended temperature operation is required.

🏭

High-Speed Data Acquisition Front-Ends

Test-and-measurement digitizers and oscilloscope front-ends need multi-gigabit serial links to stream ADC data to a host processor. The EP1AGX35DF780 pairs its 3.125 Gbps transceivers with hard multipliers (for FIR decimation filters), 1.34 Mbit embedded RAM (for sample buffering), and 341 user I/Os (to interface LVDS ADCs). The industrial temperature grade makes it suitable for bench, ATE, and field-portable instruments that must operate across wide thermal ranges.

🏭

Industrial Protocol Bridging

Factory automation gateways must bridge legacy fieldbuses (Profibus, RS-485, CAN) to modern Ethernet/IP and EtherCAT networks. The EP1AGX35DF780's high-speed transceivers handle Ethernet PHY duties, while its abundant logic implements soft-core CPUs (Nios II) for protocol translation, 1.34 Mbit RAM buffers packets, and 341 user I/Os drive multiple fieldbus interfaces simultaneously. Industrial-grade parts ensure reliable operation in 50C cabinet environments with high EMI.

📡

Wireless Baseband Processing

Small-cell and pico-cell baseband designs use mid-range FPGAs like the EP1AGX35DF780 for CPRI front-haul, digital up/down-conversion, and channel-card aggregation. The 8 transceivers carry CPRI up to 3.072 Gbps, the 18x18 multipliers perform crest-factor reduction and digital pre-distortion, and the 1.34 Mbit RAM stages buffers between PHY and baseband DSP. Migration to Arria II GX (40 nm) reduces power per channel by ~40%, critical for outdoor radio units.

What is the EP1AGX35DF780 and which FPGA family does it belong to?
The EP1AGX35DF780 is a member of Altera's Arria GX family of FPGAs, fabricated on a 90 nm process and offering 33,520 logic elements, 1.34 Mbit of embedded RAM, and up to 8 transceiver channels operating at 3.125 Gbps per channel. It is housed in a 780-ball FineLine BGA and was originally launched by Altera (now Intel) as a mid-range FPGA bridging Cyclone II and Stratix II/III for serial-I/O centric designs.
How many transceivers does the EP1AGX35DF780 have and what is the maximum data rate?
The EP1AGX35DF780 integrates up to 8 full-duplex 3.125 Gbps CMU/CDR transceiver channels, the headline feature of the Arria GX family. These hard PCS/PMA channels support common serial protocols including PCI Express (x1/x4), Gigabit Ethernet, Serial RapidIO, SDI/HD-SDI, and Aurora, eliminating the need for external SERDES chips in mid-bandwidth applications.
Where can I download the EP1AGX35DF780 datasheet PDF?
The official Altera/Intel Arria GX device handbook (multi-volume) covers the EP1AGX35DF780 and is available on the Intel FPGA documentation portal under legacy Arria GX support. Third-party datasheet mirrors such as alldatasheet.com and datasheets.com also host PDF copies of the family datasheet for archival reference, though Intel's website is the authoritative source for errata.
What package does the EP1AGX35DF780 use and how many user I/Os does it expose?
The EP1AGX35DF780 is offered in a 780-ball FineLine BGA (FCBGA) approximately 29x29 mm with 1.0 mm ball pitch. The package exposes up to 341 general-purpose user I/Os plus the 8 transceiver differential pairs, organized as banks that each support a mix of single-ended, LVDS, and HSTL/SSTL memory-interface signaling standards.
Is the EP1AGX35DF780 still in production or has it been discontinued?
The EP1AGX35DF780 is classified as obsolete in Intel FPGA's current product tree - the Arria GX family reached end-of-life years ago and is no longer recommended for new designs. Existing inventory is available from authorized distributors like Rochester Electronics (which holds legacy Altera stock) and from independent brokers, but lead times are volatile and prices have escalated as supply has tightened.
Where can I buy the EP1AGX35DF780 today and what is the typical price?
Authorized-channel inventory is limited; DigiKey lists the EP1AGX35DF780C6 through Rochester Electronics LLC, Mouser lists the EP1AGX35DF780C6N, and LCSC Electronics shows pricing around $217.14 per unit as of September 2026. Independent brokers may quote higher or lower depending on lot traceability; always request C-of-C and date code documentation when sourcing EOL FPGAs.
What is the lead time for the EP1AGX35DF780?
Lead time for the EP1AGX35DF780 is no longer a manufacturer-published figure - it depends entirely on distributor and broker stock. Authorized franchised distributors such as Rochester Electronics typically quote 6-12 weeks for back-order fulfillment on legacy Altera FPGAs, while independent brokers can ship from in-house inventory within days but at a premium price.
What is the difference between the EP1AGX35DF780 and EP1AGX20CF780 variants?
The EP1AGX35DF780 contains 33,520 logic elements and is part of the earlier Arria GX family, while the EP1AGX20CF780 is a 20,060-LE member of the cost-optimized Arria II GX family. The DF780 package is on Arria GX, the CF780 package is on Arria II GX - they are pin-compatible in some footprint variants but differ in transceiver count, DSP blocks, and process node (90 nm vs 40 nm).
Is there a pin-compatible drop-in replacement for the EP1AGX35DF780?
There is no exact pin-compatible drop-in replacement for the EP1AGX35DF780 because it has reached end-of-life and the Arria GX family was unique. The closest modern substitutes are Arria II GX (40 nm), Cyclone V GT, or Lattice ECP5-based boards, but all require PCB re-spin, firmware updates, and re-qualification. Designers should plan for a migration path rather than seek a true drop-in.
Can the Lattice ECP5 or Xilinx Spartan-6 directly replace the EP1AGX35DF780?
No - the Lattice ECP5, Xilinx Spartan-6, and other mid-range FPGAs are not pin-compatible with the EP1AGX35DF780. While they offer comparable logic density, transceiver counts, and DSP capability, they are different package footprints with different bank voltages and pin assignments, so any swap requires a full PCB redesign and firmware migration. Treat them as functional equivalents rather than drop-in replacements.
What external memory interfaces does the EP1AGX35DF780 support?
According to the Arria GX device handbook, the EP1AGX35DF780 supports DDR, DDR2, QDRII, and QDRII+ SRAM external memory interfaces through dedicated DQS phase-shift circuitry on each I/O bank. Maximum data rates depend on speed grade (C6 vs C7) but are typically up to 333 MHz DDR2 or 300 MHz QDRII for the larger 780-pin package variants.
What configuration methods does the EP1AGX35DF780 support?
The EP1AGX35DF780 supports Passive Serial (PS), Fast Passive Parallel (FPP), and Altera-enhanced configuration modes using EPCS serial configuration devices or EPC enhanced parallel configuration devices. JTAG 1149.1 boundary-scan is also supported for board-level testing and in-system programming through the standard 10-pin or USB-Blaster header.
Is the EP1AGX35DF780 RoHS compliant?
Lead-free RoHS-compliant variants of the EP1AGX35DF780 exist and were shipped with the 'N' suffix designation. Pre-RoHS lead-bearing variants may also exist in older distributor inventory; engineers specifying into new designs should explicitly order the 'N' suffix to guarantee lead-free compliance with EU Directive 2011/65/EU.
What is the operating temperature range of the EP1AGX35DF780?
Industrial-grade variants (denoted by the 'I' suffix, e.g., EP1AGX35DF780I6) are specified for -40C to +100C junction temperature, while commercial-grade variants (C6/C7 speed grade) are rated for 0C to +85C ambient. The 'I' suffix is required for outdoor, automotive, or industrial control applications where the device must survive extended thermal cycling.
What are the key technical specifications of the EP1AGX35DF780 that engineers should know?
Key specs: 33,520 logic elements, 1.34 Mbit embedded RAM, 341 user I/Os, up to 8 transceivers at 3.125 Gbps each, 4 PLLs, 18x18 hard multipliers, 90 nm process, 1.0 mm pitch 780-ball FCBGA package. The combination of mid-range logic density with embedded multi-gigabit transceivers made it a popular choice for protocol-bridging and telecom backplane designs from 2007-2015.

Selection Guide

Choose the EP1AGX35DF780 when you have existing Arria GX designs that you need to keep in production and are willing to navigate EOL supply. For new designs, strongly consider the EP1AGX35CF780I6N (Arria II GX, same 780-BGA footprint, 40 nm, lower power) as the natural migration path. Choose EP1AGX20CF780I6N when logic density is sufficient and cost matters more than per-channel power. Avoid cross-vendor FPGAs (Xilinx Spartan-6, Lattice ECP5) as drop-in replacements - they require PCB redesign. All variants are obsolete in 2026, so plan long-term procurement through Rochester Electronics or qualified brokers, and always require date-code and C-of-C documentation.

Key Differentiators

  • Highest logic density in the Arria GX 780-FBGA family (vs EP1AGX20CF780I6N)
  • Arria II GX (40 nm) migration available in same 780-BGA footprint (vs EP1AGX35CF780I6N)
  • Industrial temperature variants available for harsh environments (vs EP1AGX20CF780C6N)

Design Notes

Estimated: at full transceiver utilization (8 channels @ 3.125 Gbps) and 75% logic toggling, junction power can exceed 5 W. The 780-ball FCBGA (29x29 mm) has theta_JA in the 15-20 C/W range on a JEDEC 4-layer test board, requiring at least a moderate copper pour or a heatsink for industrial-temperature operation. Use the Altera PowerPlay Early Power Estimator before RTL completion to budget thermal dissipation and validate regulator sizing. Always apply thermal interface material (TIM) if a discrete heatsink is used.

The 780-ball FCBGA uses a 1.0 mm ball pitch - the PCB must follow IPC-7351 land-pattern guidelines and use NSMD (non-solder-mask-defined) pads for best joint reliability. Stack-up should specify 4-6 mil laser-drilled microvias for breakout and a continuous GND plane on layer 2 to provide return paths for high-speed transceivers. Per JEDEC J-STD-020, the device is MSL3 (30C/60% RH floor life 168 hours) - bake-out is required if the factory floor exposure exceeds that window.

Transceiver channels require 100-ohm differential pairs routed with controlled impedance (typically 85-ohm on inner stripline layers, 90-ohm on microstrip) and length matching to within 5 mils within a channel and 50 mils across a group for protocols like PCIe. Keep AC-coupling capacitors close to the transmitter pins and provide solid GND return stitching vias every 200 mils along the trace route to minimize EMI and signal-integrity issues.

Do not assume the EP1AGX35DF780 can be hot-swapped or live-updated without verifying configuration scheme support. When migrating to Arria II GX (40 nm) on the same 780-BGA footprint, double-check pinout compatibility via the Altera pin migration tool - while the high-level ball map is similar, several transceiver supply pins and JTAG pin assignments changed between the two generations, and a naive swap will short power rails.

Estimated: VCCINT (core) typically 1.2 V and VCCIO (I/O banks) at 1.5/1.8/2.5/3.3 V depending on bank assignment. Always sequence supplies per Altera's recommended power-up sequence - VCCINT before VCCAUX before VCCIO - to prevent latch-up during board power ramp. Decouple each supply pin with 0.1 uF X7R ceramic placed within 100 mils, plus bulk decoupling of 10-100 uF tantalum or polymer per supply rail.
