EP1SGX25DF67216 概要
A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and dedicated hard-IP blocks such as transceivers, memory, and DSP. FPGAs sit at the top of the programmable logic hierarchy between CPLDs (smaller, lower-density) and ASICs (higher-NRE, higher-volume). The Stratix GX specifically extends this hierarchy into high-speed serial I/O, combining general-purpose FPGA fabric with multi-gigabit transceivers (MGTs) for protocols like PCI Express, Gigabit Ethernet, Serial RapidIO, and XAUI.
Key features of the EP1SGX25DF67216 include 8 transceiver channels (4 in each of two banks) operating at 500 Mbps to 3.1875 Gbps, on-die termination (ODT) for 100-ohm differential lines, programmable transmitter pre-emphasis and receiver equalization, a 1.5-V core supply, 1,944,576 RAM bits organized as M4K/M-RAM blocks, and 4 dedicated PLLs for clock synthesis. The device supports up to 3 single-ended I/O standards per bank with hot-socketing capability.
Architecturally, the Stratix GX family uses a 1.5-V core with a TriMatrix memory structure (640-bit M512, 4-Kbit M4K, 512-Kbit M-RAM) and dedicated DSP blocks for high-throughput arithmetic. Embedded SERDES with clock data recovery (CDR) eliminates external PHY chips, while the high-speed transceiver interface (HSTI) provides a hard-coded PCS layer with 8B/10B encoding, rate matching, and word alignment.
Typical applications include high-speed serial interface bridging (PCI Express x1/x4 endpoint, Gigabit Ethernet MAC, Serial RapidIO), telecommunications backplane aggregation, broadcast video transport (SD-SDI/HD-SDI), storage area network interconnects (Fibre Channel), and defense/aerospace signal processing back-ends. The 3.1875 Gbps per channel raw rate translates into approximately 2.5 Gbps usable bandwidth after 8B/10B overhead.
When designing with this device, allocate a separate PLL per transceiver block group and keep the 1.5-V core and 3.3-V auxiliary supplies well-decoupled with 100 nF X7R capacitors within 100 mils of each ball. Maintain 100-ohm differential impedance on all transceiver traces and use a 4-layer PCB with continuous ground beneath the BGA to limit crosstalk.

主な用途
EP1SGX25DF67216 の用途: 6 件s: PCI Express Endpoint Card, Gigabit Ethernet Switch Line Card, 1G/2G Fibre Channel Storage Controller, Serial RapidIO Switch / Endpoint, SD-SDI / HD-SDI Broadcast Video Transport, Defence / Aerospace Signal Processor.
PCI Express Endpoint Card
The EP1SGX25DF67216 fits PCIe 1.1 endpoint designs at x1/x4 lane widths because its hard-IP PCIe block consumes 2.5 Gbps transceivers and 8B/10B encoding without building the PHY/MAC/transaction layer in soft logic. The 25,660 logic elements and 1,944,576 bits of RAM comfortably host DMA engines, BAR mapping, MSI interrupt controllers, and the application layer, while the 8 transceiver channels support up to x8 endpoints for higher-throughput designs. Compared with a Virtex-II Pro + RocketIO solution, the Stratix GX cut BOM cost by integrating the SERDES and CDR on-die, reducing board area and signal-integrity risk.
おすすめ
Gigabit Ethernet Switch Line Card
Gigabit Ethernet line cards using 1000BASE-X SFP/SFP+ cages or 1000BASE-T PHY interfaces benefit from the EP1SGX25DF67216 because its transceivers run cleanly at 1.25 Gbps with 8B/10B PCS support, while the FPGA fabric implements GMII/RGMII conversion, MAC filtering, and L2 switching logic. The 672-ball BGA provides sufficient I/O for SGMII/SFP cage control, MDIO management, and switch fabric back-pressure signals, and 1.94 Mbit of RAM is enough for 4 deep packet-inspection queues. Compared with discrete MAC + PHY implementations, this single-chip approach halves board area and BOM cost.
おすすめ
1G/2G Fibre Channel Storage Controller
Fibre Channel 1G (1.0625 Gbps) and 2G (2.125 Gbps) speeds sit comfortably inside the EP1SGX25DF67216's 500 Mbps to 3.1875 Gbps transceiver envelope, and the hard-coded 8B/10B encoder plus the on-die CDR eliminate the external FC PHY chip common in early 2000s SAN designs. The 4 PLLs synthesize the per-port reference clocks and the FC-1 framing/primitive signalling without taxing the soft-logic block, while 1,944,576 bits of RAM buffer FC frames for cut-through or store-and-forward modes. Storage OEMs leveraged the part for RAID HBAs, FC-to-SATA bridges, and tape-backup accelerators.
おすすめ
Serial RapidIO Switch / Endpoint
Serial RapidIO (SRIO) at 1.25, 2.5, and 3.125 Gbps uses the same 8B/10B PCS layer that the EP1SGX25DF67216 transceivers already implement, allowing a designer to focus on the SRIO logical/transport/physical layers in soft logic rather than the serializer. With 8 transceiver channels, the device can implement an SRIO 4x port switch fabric or a 1x/4x endpoint with margin for DSP preprocessing, message-passing FIFOs, and DMA. Industrial SRIO uses include base-station baseband cards, DSP cluster aggregation, and high-speed backplane interconnects in defence systems.
おすすめ
SD-SDI / HD-SDI Broadcast Video Transport
SD-SDI (270 Mbps) and HD-SDI (1.485 Gbps / 1.485/1.001 Gbps) over coax are well within the EP1SGX25DF67216's 500 Mbps to 3.1875 Gbps data-rate window, and the on-die SERDES eliminates external SDI cable equalizers/buffers in some designs. The FPGA fabric implements scrambling (NRZI to NRZ), line-number/crc insertion, embedded audio demux, and ANC data extraction, while 1.94 Mbit of RAM buffers multi-line video frames for genlock and frame-sync functions. Broadcast OEMs used the Stratix GX family for cross-converters, up/down/cross-format scalers, and routing switchers where the integration of transceivers with a large programmable fabric shortened time to market.
おすすめ
Defence / Aerospace Signal Processor
Defence and aerospace signal-processing back-ends running at 2.5 Gbps such as radar digitizers, electronic-warfare receivers, and secure-radio baseband use the EP1SGX25DF67216 because the transceivers interface directly to high-speed ADCs/DACs and FPGA mezzanine cards (FMC/VITA 57), while 25,660 logic elements implement FFT, channelization, and digital down-conversion. The 672-ball BGA with 1.0-mm pitch supports ruggedized underfill and lidless assemblies required for MIL-STD-810 thermal and vibration profiles. Long-term support from Rochester Electronics makes the part viable for defence programs that need 10+ year lifecycle continuity.

設計ノート
The EP1SGX25DF67216 requires a 1.5-V VCCINT core rail capable of sourcing 1.2-1.8 A depending on toggle rate, a 3.3-V VCCPD rail at ~150 mA, and per-bank VCCIO supplies. Each active transceiver channel draws approximately 80-120 mA from the VCCR/VCCT analog supplies; with 8 channels engaged, allocate a separate 2.5-V filtered analog LDO. Decoupling recommendation per Stratix GX handbook: 100 nF X7R placed within 100 mils of every supply pin, plus 10 uF bulk per rail. Estimated: with 8 transceivers active at 3.1875 Gbps and 50% logic utilization, total power consumption is approximately 5-7 W; the FineLine BGA thermal pad must be soldered to a 1-oz copper pour of at least 1 square inch to keep junction temperature below 100 C in still air.
Each transceiver differential pair (RXP/RXN, TXP/TXN) must be routed as a 100-ohm differential transmission line on a 4-layer PCB with continuous reference ground beneath the BGA. Use 5-8 mil trace width and 6-8 mil gap on a 0.8-1.0 mil dielectric above the ground plane; 0.5-oz copper reduces skin-effect loss at 3.1875 Gbps. Keep the AC-coupling capacitors (typically 100 nF X7R, 0402) within 200 mils of the receiver pins. Series capacitors on TX and parallel capacitors on RX per Stratix GX pin connection guidelines. The CDR lock range is sensitive to reference-clock jitter; use a crystal oscillator with sub-1 ps RMS phase noise at 156.25 MHz (or 100-650 MHz) to avoid lock failure.
Three common pitfalls when designing with the EP1SGX25DF67216: (1) power-on sequence - VCCINT must ramp before VCCPD, otherwise configuration latches can be latched-up. (2) Configuration mode - the MSEL pins select Active Serial, Passive Serial, Fast Passive Parallel, or JTAG; pull-up/pull-down resistors on MSEL[0..3] are mandatory even in JTAG-only designs. (3) JTAG chain - if the EP1SGX25DF67216 shares a JTAG chain with other devices, the Stratix GX requires the most recent Quartus II version to recognize the silicon ID; older versions of Quartus below 7.2 will fail to enumerate the part. Estimated: configuration flash memory should be a 16-Mbit or larger EPCS16/64 device, programmed via Quartus II Programmer or JTAG indirect mode.
The 672-ball FineLine BGA has a junction-to-ambient thermal resistance (theta_JA) of approximately 12-15 C/W on a 4-layer JEDEC test board with the center thermal pad soldered. At 5 W total power, this yields a 60-75 C junction-temperature rise above ambient, which is acceptable for industrial applications (max junction 100 C). For extended-temperature (100 C ambient) or ruggedized applications, use 1-oz copper pours on all four PCB layers stitched with 0.3-mm thermal vias in the BGA center pad. Reduce power by gating unused transceivers (placing the channel in PWDN mode via the Quartus transceiver toolkit) and minimizing logic utilization with clock gating.
