EP1AGX20CF780C6N 개요
An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs/LABs), programmable routing, and dedicated hardware blocks such as memory, DSP, PLLs, and (on transceiver families) multi-gigabit transceivers. FPGAs belong to the broader category of programmable logic devices (PLDs) within the integrated-circuit hierarchy: PLD -> CPLD/FPGA -> FPGA with transceivers -> SoC FPGA. Unlike a fixed-function ASIC, an FPGA's logic and routing can be redefined after manufacture, making FPGAs ideal for prototyping, low-volume production, and applications requiring post-deployment firmware upgrades. The Arria GX family specifically targets cost-sensitive designs that need integrated transceivers without the cost premium of the high-end Stratix family.
Key features of the EP1AGX20CF780C6N include built-in CDR/PMA for serial protocols such as PCI Express, Gigabit Ethernet, Serial RapidIO, and XAUI, up to 6.5 Mbits of dedicated on-chip memory configurable as true dual-port or simple dual-port RAM, and embedded DSP blocks that support 18x18 multipliers at up to 250 MHz. The device supports configuration via passive serial (PS), fast passive parallel (FPP), active serial (AS), and JTAG modes using Altera/Intel Quartus II design software.
The EP1AGX20CF780C6N's transceiver capability, dense logic, and large memory capacity make it particularly well-suited for high-speed serial interface bridging in communications equipment, low-cost PCI Express endpoint cards, broadcast video processing engines, and DSP co-processing. The flip-chip FBGA-780 package provides the necessary signal and power integrity for multi-gigabit SERDES operation. The C6 speed grade balances timing margin and cost for most commercial applications.
When designing with the EP1AGX20CF780C6N, allocate at least eight PCB layers with continuous VCC and GND planes, route all transceiver channels with controlled 100-ohm differential impedance, and provide DC-blocking capacitors on each serial TX/RX pair. Decoupling must include 100 nF X7R capacitors within 100 mil of every VCC pin to meet multi-gigabit transceiver jitter budgets.

일반적인 애플리케이션
EP1AGX20CF780C6N 적합 용도: 6 애플리케이션s: PCI Express Gen1 Endpoint Cards, Gigabit Ethernet Aggregation / Bridging, Broadcast Video Processing Engines, Software-Defined Radio Baseband / DSP Co-Processing, Industrial Camera and Machine Vision Frame Grabbers, Multi-Protocol Backplane SERDES Bridges.
PCI Express Gen1 Endpoint Cards
The EP1AGX20CF780C6N's four 3.125 Gbps transceivers make it a strong fit for PCI Express Gen1 (2.5 Gbps) endpoint cards in cost-sensitive servers, video capture cards, and industrial I/O. Its 21,580 logic elements comfortably host the standard PCIe protocol stack plus a user application such as 4-lane DMA, packet processing, or image buffering, while 1.2 Mbits of on-chip RAM provides FIFO buffering between the PCIe engine and application logic. The commercial temperature grade (0-85 C) suits typical chassis environments. Use the Altera PCIe Compiler megacore within Quartus II to access the integrated PIPE interface and shorten time-to-prototype.

Gigabit Ethernet Aggregation / Bridging
With 3.125 Gbps transceivers and sufficient logic to encode/decode 1000BASE-X and 10GBASE-R MACs, the EP1AGX20CF780C6N is commonly used in multi-port gigabit Ethernet switches and protocol bridges. A typical 4-port gigabit switch with frame buffering fits within 20K logic elements and 1.2 Mbits of block RAM, leaving headroom for an embedded Nios II management CPU. Designers benefit from the transceiver CDR/PMA eliminating external PHY parts, reducing BOM cost and PCB area. Industrial networks using EtherCAT or PROFINET also leverage these same transceivers and deterministic soft-logic timing.
추천
Broadcast Video Processing Engines
The 21,580 logic elements and 14 dedicated 18x18 multipliers support SDI/HD-SDI video processing pipelines including color-space conversion, scaling, deinterlacing, and frame-rate conversion at 1080i or 720p. Memory bandwidth from the on-chip RAM and external DDR2 controllers accommodates multiple line buffers, while 341 user I/O pins allow direct interfacing to multiple parallel video busses and DVI/HDMI serializers. The 90 nm Arria GX family was specifically designed with broadcast video OEMs as a target application, so reference designs and IP are widely available in the literature.
추천
Software-Defined Radio Baseband / DSP Co-Processing
The 14 dedicated DSP blocks of 18x18 multipliers each run at up to 250 MHz, yielding aggregate multiply-accumulate throughput of 3.5 GMACs - sufficient for UMTS/HSPA channel-card processing, DVB-T demodulator baseband, or generic DSP co-processing paired with a host DSP or ARM CPU. The 1.2 Mbits of dual-port RAM holds coefficients and ping-pong samples. Multi-gigabit transceivers connect directly to ADC/DAC JESD-style interfaces on newer front ends, or to legacy parallel interfaces on legacy radio designs. The C6 speed grade comfortably meets typical 122.88 MHz sample-rate timing.

Industrial Camera and Machine Vision Frame Grabbers
For industrial machine-vision cameras and frame-grabber cards, the EP1AGX20CF780C6N provides the SERDES links to Camera Link, CoaXPress, or GigE Vision receivers, plus the logic for color interpolation, Bayer demosaicing, and JPEG/H.264 compression at typical 1-2 megapixel resolutions. 341 user I/Os make parallel Camera Link Base/Medium/Full implementations feasible. The device's 3.3 V tolerant I/O with programmable drive strength simplifies interfacing to legacy industrial sensors. Fan-out to multiple industrial protocols is supported with on-chip LVDS transceivers for high-speed serial control links.
추천
Multi-Protocol Backplane SERDES Bridges
The four multi-gigabit transceivers running at 1 Gbps to 3.125 Gbps support simultaneously running SERDES protocols including Serial RapidIO, XAUI (4-lane 10 GigE), and Aurora for point-to-point chip-to-chip backplane links. The EP1AGX20CF780C6N therefore serves as a flexible multi-protocol bridge between ASICs, ASSPs, and DSP clusters in telecom infrastructure such as ATCA or MicroTCA cards. The large 341-pin package reserves the IO necessary to maintain LVCMOS side-band control channels. Reference designs for Serial RapidIO and XAUI are available in the Altera IP catalog.

설계 노트
The FBGA-780 flip-chip package requires at least eight PCB layers with continuous VCCINT_1.2V and GND planes, and exact 1.0 mm ball pitch pads with 0.5 mm finished hole/diameter vias-in-pad under the BGA array. Use at minimum HDI microvia stack-ups (e.g., 1+N+1). Decoupling must place 100 nF X7R within 100 mil of every VCCINT/VCCPD pin and bulk 10 uF X5R on each power plane. Series resistors on JTAG TCK/TMS/TDI/TDO reduce signal overshoot on long programming cables.
Each multi-gigabit transceiver channel pair (GXB_RX[0]+/-, GXB_TX[0]+/-, etc.) must be routed as a 100-ohm differential pair with length matching of 150 mil or less between P and N. Use AC-coupling capacitors (10 nF X7R) on TX outputs and RX inputs. Reference the Altera AN 480: High-Speed Board Design for Transceiver-Based FPGAs for stack-up, via placement, and connector recommendations. Failure to control impedance will close the eye diagram and prevent link bring-up.
Estimated: typical 1.2V VCCINT core current at maximum utilization of 21,580 LE plus 4 active transceivers is ~1.5 to 2.0 A, while VCCIO current depends on I/O bank count and toggle rate but can exceed 1.0 A. Use a minimum 4-layer regulator arrangement (LDO for noise plus switching pre-regulator) per the Arria GX PowerPlay early estimator. JTAG IDCODE must be loaded from the SOF file before any passive serial configuration to avoid MSEL sampling errors at boot. Refer to the configuration handbook section 9 for boot sequence debugging.
