MPN: EP2AGX125EF29C6G ✓ פעילEP2AGX125EF29C6G סקירה
An FPGA (Field-Programmable Gate Array) is a class of programmable logic device (PLD) that combines configurable logic blocks, programmable interconnect, and a hierarchy of embedded memory and DSP resources. FPGAs sit above CPLDs in the programmable logic taxonomy and below fixed-function ASICs in per-unit cost, occupying the sweet spot where high logic density, parallel processing, and reconfigurability are required. Within Intel's portfolio, the Arria II GX family targets mid-range applications that need integrated transceivers, embedded transceivers, and PCI Express hard IP without migrating to the higher-cost Stratix series.
Key features of the EP2AGX125EF29C6G include up to 8.315 Mbits of embedded SRAM, embedded 18x18 multipliers for DSP, up to 8 high-speed transceivers per device family, hard PCI Express Gen1/Gen2 controllers, and a comprehensive clock management network with PLLs. The device supports JTAG (IEEE 1149.1) and passive/active configuration schemes including fast passive parallel (FPP) and active serial (AS). The 780-BGA package exposes 372 user I/O and provides the signal integrity needed for DDR2/DDR3 external memory interfaces running up to 533 MHz.
The Arria II GX architecture uses adaptive logic modules (ALMs) rather than legacy 4-input LUTs, delivering finer-grained packing efficiency. The transceiver blocks support data rates up to 6.375 Gbps, enabling protocols such as PCIe Gen2, Serial RapidIO, and CPRI. The on-chip PLLs (up to 8 per device) support fractional-N synthesis, simplifying multi-frequency clock trees common in wireless baseband and video broadcast infrastructure.
Typical applications include wireless baseband processing, video broadcast and contribution encoders, high-speed test and measurement backplanes, military signal processing cards, and PCI Express Gen2 endpoint/root-port designs. The combination of embedded transceivers, hard PCIe IP, and abundant logic also suits the device for medical imaging pre-processing and industrial high-speed vision pipelines.
When designing with this device, allocate sufficient PCB area for the 780-BGA footprint (29 mm x 29 mm) and a multi-layer stack-up (typically 8-12 layers) to maintain signal integrity on the transceiver channels. Use the Quartus II design suite (or its successor) for synthesis, place-and-route, and timing closure. For power estimation, plan for a worst-case TDP near 13-14 W; an appropriately-sized thermal solution or airflow is required in enclosed chassis.

הערות תכנון
Estimated: Arria II GX devices at full transceiver utilization and ~85% logic utilization typically dissipate 10-14 W in commercial 780-BGA packages. With theta_JA of approximately 8-10 C/W (still-air, JEDEC JESD51 conditions), the junction-to-ambient rise alone is insufficient for closed chassis; provide at least 200 LFM airflow, a heat spreader, or attach a heatsink with thermal interface material. Use the Quartus II PowerPlay early power estimator before final PCB layout to size the thermal solution accurately.
The 780-BGA F29 package requires an 8-12 layer PCB stack-up with continuous GND and PWR planes. Use 1.0 mm BGA pitch escape rules with microvia-in-pad or dog-bone fan-out to break out the inner rows. Maintain 100 ohm differential impedance on the transceiver channels and 50 ohm SE for general-purpose I/O. Reference the Altera Arria II GX device handbook pin tables (Pin Connection Guidelines chapter) for bank-VCC requirements, including the dedicated VCCPD, VCCPT, and VCCA_FPLL rails.
Plan for a multi-rail power solution with sequenced enable signals: 0.9 V VCCINT, 1.1 V VCCPT, 2.5 V VCCPD (or 3.0 V depending on bank mix), 1.2 V transceiver PLLs, and 1.5 V/1.8 V DDR2/DDR3 interface voltages. Use a power management IC with the LTM4630 or similar multi-rail module for a compact solution. Decoupling per Altera guidelines is 100 nF at every VCC pin plus 10 uF and 47 uF bulk capacitors at the supply plane entries.
For PCIe Gen2 and Serial RapidIO at 5 Gbps, the transceiver reference clocks must be sourced from a low-jitter oscillator (e.g., SiTime SiT9121 or equivalent) with jitter under 100 fs RMS over 12 kHz-20 MHz. Place the clock driver within 5 cm of the FPGA clock input and isolate the high-speed region with a continuous reference plane. Use the Quartus II IBIS-AMI models for pre-layout channel simulation.
Do not assume a F25 package device (e.g., EP2AGX125DF25C6G) is a drop-in for an F29 design (EP2AGX125EF29C6G) - the pinout and transceiver mapping differ. Always verify the package suffix in the OPN against the schematic's footprint. Another common mistake is to use the EPCS configuration device with a wrong silicon ID; Arria II GX requires a compatible AS configuration device (e.g., EPCS64 or EPCQ16) and the Quartus programmer must match the device ID.
