Typical Applications
EP1AGX20CF484C6N is suitable for 6 applications: PCI Express to Gigabit Ethernet Bridge Card, Telecom Serial Backplane Line Card, Broadcast Video Processing Equipment, Industrial Machine Vision Camera Interface, Test and Measurement Instrumentation, Legacy Industrial Control System Replacement.
PCI Express to Gigabit Ethernet Bridge Card
The EP1AGX20CF484C6N's four 3.125 Gbps transceiver channels with embedded PCS/PMA layers make it ideal for bridging PCI Express Gen1 (2.5 Gbps) to Gigabit Ethernet in network adapter cards. With 21,580 LEs and 1.2 Mbit of embedded RAM, the FPGA implements the PCIe TLP layer, Ethernet MAC, and protocol conversion logic without external PHY silicon. The transceiver's 8B/10B encoding and clock data recovery support both x1 PCIe and 1000BASE-X Ethernet simultaneously. Reference design: Altera AN-456 (PCI Express Endpoint Reference Design) adapted for Arria GX.
Recommended
Telecom Serial Backplane Line Card
In telecom line cards with Serial RapidIO or XAUI backplane interfaces, the EP1AGX20CF484C6N provides exactly four 3.125 Gbps lanes to implement a quad-port serial interface. The 230 user I/Os handle parallel sideband signaling, GPIO, and front-panel LEDs. The FBGA-484 footprint exposes the four full-duplex transceiver pairs plus reference clocks required for telecom timing architectures. Industrial temperature rating (-40C to +85C) supports outdoor cabinet deployment. The on-chip PLLs synthesize multiple backplane frequencies from a single reference oscillator.
Recommended
Broadcast Video Processing Equipment
Serial digital interface (SDI) video routing and processing equipment benefits from the EP1AGX20CF484C6N's combination of 3.125 Gbps transceivers and 21,580 LEs. The transceivers carry SD-SDI, HD-SDI, and 3G-SDI signals up to 2.97 Gbps without external PHY. The 1.2 Mbit of embedded RAM buffers frame data for cross-point switching and format conversion. The 230 user I/Os connect to GPIO expanders, audio embedders, and control processors. Industrial temperature rating suits 24/7 broadcast rack environments.
Recommended
Industrial Machine Vision Camera Interface
Machine vision systems using Camera Link, CoaXPress, or GigE Vision protocols leverage the EP1AGX20CF484C6N's transceiver channels for high-speed image data reception. The four 3.125 Gbps lanes support up to 10 Gbps aggregate bandwidth, sufficient for multi-megapixel line-scan cameras. The 21,580 LEs implement image preprocessing (tap balancing, pixel correction, format conversion) before forwarding data via PCIe or Ethernet. The industrial temperature range and BGA package suit factory floor vibration and thermal environments.
Recommended
Test and Measurement Instrumentation
Test equipment such as protocol analyzers, BERT testers, and oscilloscope acquisition cards use the EP1AGX20CF484C6N to implement pattern generation and error detection at multi-gigabit rates. The four transceiver channels support simultaneous multi-lane protocol analysis (PCIe, SATA, XAUI). The 1.2 Mbit embedded RAM stores captured waveform samples, while the 230 user I/Os interface to front-panel displays and trigger logic. The combination of logic capacity and transceiver count at this price point has historically made it a popular T&M FPGA.
Recommended
Legacy Industrial Control System Replacement
For maintaining installed industrial control systems that were designed around the Arria GX family, the EP1AGX20CF484C6N provides a like-for-like replacement when original parts fail. The exact FBGA-484 footprint matches the original PCB layout, and the 21,580 LE logic capacity matches the original design's resource utilization. Using the same part family eliminates firmware recompilation and field revalidation effort. Industrial temperature rating and surface-mount BGA packaging suit harsh factory environments when sourced through qualified distributors.

Key Differentiators
- Lowest density Arria GX variant with full 4-channel transceiver support (vs EP1AGX35CF484C6N)
- Industrial temperature rating vs commercial-only equivalent (vs EP1AGX20CF484C6)
- C6 speed grade balances timing margin and cost (vs EP1AGX20CF484C3)
Design Notes
Arria GX devices require multiple separate supply rails: VCCINT (core, typically 1.2V), VCCPD (I/O pre-driver, 2.5V or 3.0V), VCCA_PLL (analog PLL, 2.5V), VCCA_TX and VCCA_RX (transceiver analog, 2.5V or 3.3V), and VCCIO (per-bank I/O, 1.5V to 3.3V). Each rail requires its own decoupling network following the Arria GX Device Handbook recommendations. Power sequencing is critical - VCCINT must ramp before VCCPD to prevent latch-up. Estimated: total quiescent power for the EP1AGX20CF484C6N with all four transceivers active at full utilization is approximately 5-8W; verify against PowerPlay early-estimate tool.
The FBGA-484 package at 1 mm pitch requires a PCB stackup with microvia or via-in-pad technology to break out all 484 balls. Use a minimum 4-layer stackup with continuous ground planes beneath the device. Reference the Arria GX Board Design Guidelines for transceiver channel routing: 100 ohm differential impedance, maximum 5 inches trace length, AC-coupled at the transmitter. Transceiver power islands must be isolated from digital switching noise with ferrite beads or pi filters.
Do not attempt to migrate the EP1AGX20CF484C6N design to Cyclone IV GX or newer without recompiling the entire Quartus project - the package ball maps differ and the transceiver IP cores have changed across generations. Also note that Arria GX uses 1.2V VCCINT while Cyclone V GX uses 1.1V, so any power supply designed for Arria GX will need adjustment. When sourcing obsolete parts, always verify date codes are within 5 years and request lot traceability documentation from the distributor.
