EP1SGX40CF1020I5 概要
A Field-Programmable Gate Array (FPGA) is a reconfigurable semiconductor that allows engineers to implement custom digital logic, memory, DSP, and high-speed serial interfaces after PCB fabrication. FPGAs belong to the broader hierarchy of programmable logic devices (PLDs) -> logic ICs -> integrated circuits (ICs). Unlike fixed-function ASICs, FPGAs are programmed via configuration bitstreams stored in SRAM, enabling rapid prototyping, field upgrades, and design iteration without respinning silicon. The Stratix GX sub-family specifically adds multi-gigabit transceivers for serial connectivity.
Key features include high-speed embedded transceivers operating at up to 3.125 Gbps, dedicated DSP blocks for high-throughput signal processing, TriMatrix on-chip SRAM, support for multiple I/O standards (LVDS, SSTL, LVTTL), and PLLs for clock management. The fine-pitch BGA-1020 package exposes hundreds of user I/O pins and multiple dedicated high-speed serial links, enabling dense board layouts for telecom and datacom equipment.
Architecturally, the EP1SGX40CF1020I5 uses SRAM-based look-up tables (LUTs) for combinational logic, embedded block RAM (BRAM), hardware multiplier blocks for DSP, and dedicated serializer/deserializer (SERDES) circuitry. This combination allows simultaneous implementation of packet processing, forward error correction, and high-speed backplane interfaces on a single device.
Typical applications include 10 Gb Ethernet line cards, optical transport network (OTN) equipment, high-speed serial backplane aggregation, wireless baseband processing, broadcast video routing, and radar signal processing prototypes. The industrial temperature grade also suits outdoor telecom hardware and military/aerospace subsystems.
When designing with this device, allocate sufficient PCB layers for power distribution and signal integrity, follow Altera's recommended decoupling guidelines, and use the Quartus II design suite (legacy 5.x/6.x) for synthesis and place-and-route. A JTAG header and configuration memory footprint should also be planned.
This page synthesizes distributor inventory, same-family alternatives, and practical design notes not found in the original manufacturer datasheet, helping engineers evaluate the EP1SGX40CF1020I5 for both new designs and legacy system sustainment.

主な用途
EP1SGX40CF1020I5 の用途: 7 件s: 10 Gb Ethernet Line Card Aggregation, Optical Transport Network (OTN) Framer, Wireless Baseband Processing, High-Speed Serial Backplane Aggregation, Broadcast Video Routing and Switching, Radar and Defense Signal Processing Prototypes, Industrial Control and Test Equipment.
10 Gb Ethernet Line Card Aggregation
The EP1SGX40CF1020I5 is well suited to early-2000s 10 GbE line-card designs because it integrates 41,250 logic elements together with up to 3.125 Gbps multi-gigabit transceivers in a single die. Placed on the line card as the central MAC/framer, the FPGA aggregates traffic from multiple XAUI or XGMII ports and performs packet classification, policing, and queue management. Its 3,423,744 bits of TriMatrix on-chip SRAM are large enough to buffer line-rate bursts without external TCAMs, while dedicated DSP blocks accelerate CRC and encryption offload. Compared to a discrete SERDES-plus-ASIC solution, the Stratix GX reduces BOM and enables late-stage feature updates via SRAM-based configuration. Power-supply sequencing must respect the 1.5 V core rail ramp rate per the Stratix GX datasheet to avoid in-rush latch-up.
おすすめ
Optical Transport Network (OTN) Framer
Telecom OTN framers require FEC (Reed-Solomon and/or turbo), mapping, and overhead processing at line rate. The EP1SGX40CF1020I5's combination of high logic density (41,250 LEs), embedded multipliers, and SERDES makes it an integrated OTN framer choice for OTU1/OTU2 rates. The FPGA runs the OTN framer state machine in fabric, while its on-chip RAM holds de-skew and FEC intermediate symbols, and the 3.125 Gbps transceivers interface to SFP+ optical modules directly. Compared to ASIC OTN framers, this Stratix GX delivers reconfigurability for evolving G.709 amendments. Board layout must isolate the 3.125 Gbps serializer outputs with 100-ohm differential impedance and length matching per Stratix GX layout guidelines.
おすすめ
Wireless Baseband Processing
Wireless base station prototypes and picocell baseband cards benefit from the EP1SGX40CF1020I5's DSP block count and SERDES channels. Implemented as the baseband DSP engine, the FPGA runs FFT/iFFT, channel estimation, and MIMO matrix math on chip, exploiting the dedicated multiplier blocks for QAM demodulation. The 41,250 LEs handle the control plane and CPRI/OBSAI framer glue, while the multi-gigabit transceivers connect to the radio unit over a CPRI link. Industrial temperature grade (-40 to +100C) allows placement inside outdoor radio units. Compared to a DSP+ASIC pair, this approach shortens development cycles from years to months and allows field upgrades as 3GPP releases evolve.
おすすめ
High-Speed Serial Backplane Aggregation
In AdvancedTCA or proprietary backplane routers, the EP1SGX40CF1020I5 acts as a switch-fabric glue, aggregating Serial RapidIO or custom LVDS links. Each multi-gigabit transceiver interfaces to a backplane lane at 1.25-3.125 Gbps, while the 41,250 logic elements implement the routing/scheduling fabric. Industrial temperature range and 1.5 V core operation suit controlled-environment telecom racks. Designers must follow Altera's pinout guide for the FBGA-1020 to ensure proper assignment of the dedicated transceiver reference-clock pins (GXB_REFCLK) for jitter compliance.
おすすめ
Broadcast Video Routing and Switching
Broadcast video routers (SDI at 270 Mbps, HD-SDI at 1.485 Gbps, 3G-SDI at 2.97 Gbps) map directly onto the EP1SGX40CF1020I5's SERDES capability. The device can de/embed up to 16 channels of HD-SDI per direction while the FPGA fabric handles crosspoint switching, audio de-embedding (AES/EBU), and ancillary data processing. The 33 x 33 mm BGA keeps PCB area manageable for 1U router frames. Engineers should allocate PLL and clock-tree resources carefully because each SDI channel needs a dedicated low-jitter reference per SMPTE 259M/292M.
おすすめ
Radar and Defense Signal Processing Prototypes
Defense prototyping labs adopt the EP1SGX40CF1020I5 for radar pulse compression, moving target indication, and electronic-warfare channelization. The 41,250 logic elements plus dedicated multipliers implement FFT-based processors in the multi-MHz range, and the SERDES channels accept digitized IF directly from high-speed ADCs. Industrial temperature grade suffices for many platform installations but full -55C to +125C MIL operation is not officially supported - mission-critical builds require derating or screening. Compared to ASIC implementations, the FPGA enables rapid algorithm updates against new threat libraries.
おすすめ
Industrial Control and Test Equipment
Automated test equipment (ATE) and high-end industrial controllers can leverage the EP1SGX40CF1020I5 as a custom timing-pattern generator or protocol exerciser. With 41,250 LEs, designers implement IEEE-488, parallel LVDS interfaces, and proprietary backplane protocols in fabric, while the SERDES drives gigabit serial to/from the DUT. The industrial temperature grade suits factory-floor environments. New designs should consider the obsolete lifecycle and choose modern Intel Cyclone 10 or Stratix 10 with a 33 mm-equivalent BGA footprint to ease migration.

設計ノート
The FBGA-1020 package at 1.0 mm pitch requires an 8+ layer PCB stack-up with buried microvias or via-in-pad for breakout. Estimated: a 4-layer board can route power and ground but cannot escape the full BGA-1020 within reasonable via costs; budget for a 10-layer or higher stack-up. Reference the Altera AN 75 (Stratix GX Hardware Design) for via-pattern recommendations. Keep all high-speed transceiver differential pairs length-matched to within 5 mils to meet jitter budgets at 3.125 Gbps.
The EP1SGX40CF1020I5 has separate VCCINT (1.5 V core), VCCIO (I/O bank voltage), VCCA_PLL (PLL analog supply), and VCC_GXB (transceiver analog supply) rails. Estimated: total power at full utilization approaches 15-25 W. Use a dedicated LDO for each analog rail, separate bulk and decoupling capacitors, and ensure the VCCINT ramp rate stays within Altera's specified 100 us - 100 ms window to avoid in-rush current latch-up.
Because the EP1SGX40CF1020I5 is obsolete, do not commit new designs to it unless you have a multi-year parts continuity plan. Verify configuration memory availability (EPC16/EPCS family is also obsolete), JTAG header for in-system updates, and a fallback PCB variant on a smaller or newer FPGA. Always order with date-code recency specified to avoid counterfeit risk, and request CoC and X-ray inspection on each lot.
Place a JTAG header (IEEE 1149.1) accessible at the board edge for in-system programming and boundary-scan. Reference the Quartus II 7.x JTAG Configuration Center for recommended pull-up/pull-down resistor values on TCK, TMS, TDI, and TDO. Add a configuration-error LED tied to the nCONFIG/nSTATUS pins to assist field diagnostics and a CONF_DONE indicator for programming-state visibility.
For 3.125 Gbps SERDES channels, follow Altera's high-speed layout guidelines: 100-ohm differential impedance, AC-coupled interconnects, and continuous reference planes. Decoupling on each VCC_GXB pin must use a 0.1 uF + 0.01 uF + 10 uF capacitor triple per pin or the recommended grouping. Estimated: total decoupling capacitance on VCC_GXB exceeds 200 uF for the full transceiver bank. Channel-to-channel skew tolerance must be extracted from the Quartus II timing analyzer.
