Typical Applications
EP1AGX20CF484C7N is suitable for 6 applications: Gigabit Ethernet MAC/PHY Bridge, PCI Express Endpoint Card, Serial Digital Interface (SDI) Video Bridge, Wireless Baseband Processing, Industrial Machine Vision Camera, Telecom Backplane Aggregation.
Gigabit Ethernet MAC/PHY Bridge
The EP1AGX20CF484C7N integrates 4 transceivers rated at 3.125 Gbps, which comfortably covers 1.25 Gbaud gigabit Ethernet (1000BASE-X) SERDES. Designers can pair the FPGA with the Altera Tri-Speed Ethernet MAC IP and connect directly to an SFP cage, eliminating an external PHY. The 21,580 LEs are sufficient to add bridge logic between GMII and a backplane, while 1,229,184 bits of embedded memory hold packet buffers and statistics counters. Compared with a discrete PHY plus CPLD implementation, this single-chip approach shrinks the BOM by 30-40% and reduces PCB layer count.
Recommended
PCI Express Endpoint Card
The 3.125 Gbps transceivers of the EP1AGX20CF484C7N support PCI Express Gen1 (2.5 Gbps) directly through the Altera PCIe hard IP block, freeing logic resources for endpoint application logic. The 484-BGA package exposes enough user I/Os to drive a 4-lane or 8-lane PCIe edge connector plus auxiliary control signals. With 64 embedded 18x18 multipliers, the FPGA can run endpoint DSP such as scatter-gather DMA engines. The industrial -40C to +85C temperature grade makes it suitable for workstation add-in cards, industrial controllers, and test instrumentation.
Recommended
Serial Digital Interface (SDI) Video Bridge
The Arria GX transceivers of the EP1AGX20CF484C7N natively support HD-SDI (1.485 Gbps) and 3G-SDI (2.97 Gbps) data rates without an external serializer, making the part a strong fit for broadcast video capture cards and studio equipment. The 21,580 LEs accommodate frame buffers, color-space conversion, and audio embedding/de-embedding IP cores. The 484-BGA offers the high pin density required for parallel video buses plus the SDI I/O. Industrial temperature grade and 90 nm jitter tolerance suit demanding 24/7 broadcast environments.
Recommended
Wireless Baseband Processing
The 64 embedded 18x18 multipliers in the EP1AGX20CF484C7N support baseband DSP such as FIR filters, FFT/iFFT, channel equalization, and QAM/QPSK demodulation for small-cell wireless backhaul. The 4 transceivers handle CPRI or OBSAI links to the radio unit at 1.2288 Gbps or higher line rates. The 1,229,184 bits of embedded memory buffer time-domain samples without an external SRAM, simplifying PCB layout. Industrial temperature range matches outdoor enclosure requirements for remote radio heads and micro base stations.
Recommended
Industrial Machine Vision Camera
The EP1AGX20CF484C7N can drive Camera Link, CoaXPress, or GigE Vision interfaces from its 3.125 Gbps transceivers while running image pre-processing algorithms on its 21,580 LEs. The 64 multipliers accelerate 2D convolution and Bayer demosaicing, and the 1.2 Mbits of block RAM hold line buffers for image pipelines. The 230 user I/Os expose parallel sensor interfaces and GPIO for trigger and strobe synchronization. Industrial -40C to +85C temperature support enables deployment in factory-floor vision systems where consumer-grade parts would fail.
Recommended
Telecom Backplane Aggregation
With 4 full-duplex 3.125 Gbps transceivers, the EP1AGX20CF484C7N serves as a small aggregation switch or serializer-deserializer (SerDes) front-end for telecom backplanes carrying protocols such as Serial RapidIO, Aurora, or proprietary backplane SERDES. The FPGA performs protocol translation, lane striping, and minimal buffering across the 1.2 Mbit block RAM. The 230 user I/Os drive the backplane control plane and management interfaces. Industrial temperature rating and BGA package with controlled-impedance lanes make it a proven telecom hardware platform.

Key Differentiators
- Fastest speed grade among industrial-temperature EP1AGX20CF484 variants (vs EP1AGX20CF484C6N)
- Industrial temperature grade -40C to +85C (vs EP1AGX20CF484C7)
- 4 integrated 3.125 Gbps transceivers eliminate external PHY (vs Cyclone III (no transceivers))
Design Notes
The 484-pin FineLine BGA requires microvia or via-in-pad PCB technology for reliable breakout. Use a 1.0 mm or 1.27 mm ball pitch stack-up with high-density interconnect (HDI) microvias under the BGA; standard through-via fanout may not fit between the 1.0 mm ball grid. Provide at least 4 PCB layers dedicated to GND/VCC planes below the package for transceiver return-current paths. Estimated: a 12-layer 1.0 mm-pitch HDI stack-up is typical for production designs.
Transceiver channels must be routed as 100 ohm differential pairs with length matching within 150 mils for the P and N legs and within 50 mils across the lanes of a multi-lane protocol like PCIe. Use 3D field-solver simulation for the BGA breakout and connector region; the 3.125 Gbps signals cannot tolerate stubs or 90-degree bends. The reference clock to each transceiver should be routed with the same controlled-impedance discipline; jitter on the reference clock directly degrades link BER.
The Arria GX transceiver blocks require dedicated low-noise analog supplies (VCCA) isolated from digital VCCINT and VCCIO rails. Place a ferrite bead or pi-filter between each analog and digital supply, and provide a 0.1 uF plus 10 uF local decoupling capacitor within 100 mils of every VCCA pin. Estimated: total quiescent power for the EP1AGX20CF484C7N at typical utilization is approximately 1.5-2.0 W, rising to 3-4 W with all four transceivers active at 3.125 Gbps.
Configuration mode pin (MSEL[3:0]) settings must match the selected configuration scheme - passive serial, fast passive parallel, or JTAG - or the device will fail to configure. Do not leave MSEL floating; pull each bit to VCCIO or GND through a 10 kohm resistor. When migrating between C7 and C6 speed grades, revalidate Fmax for all timing-critical paths; the C6 grade is approximately 15% slower than C7.
Compliance Information
Compliance status not found in the verified web data; the part is obsolete and datasheets for legacy Altera 90 nm products typically omit RoHS declarations. Engineers should request a manufacturer compliance letter for new production builds.
