EP1SGX40CF672C5 概覽

The Altera EP1SGX40CF672C5 is a high-density Stratix GX family FPGA integrating 41,250 equivalent logic elements (LEs), 3.42 Mbits of embedded RAM, and up to 20 full-duplex transceiver channels in a 672-pin FineLine BGA package. The device belongs to Altera's first-generation Stratix GX family, which combines a high-performance Stratix fabric with embedded multi-gigabit transceivers (MGTs), making it suited for high-bandwidth serial interconnect and protocol bridging applications.

A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), embedded memory, DSP blocks, and programmable interconnect, all controlled by a user-defined configuration bitstream. Within the broader taxonomy, an FPGA belongs to programmable logic devices (PLDs), which are a class of digital ICs that sit between ASICs and general-purpose processors. Stratix GX parts specifically target high-speed serial I/O and are commonly used in telecom backplane, broadcast video, and storage area network designs where multi-gigabit transceivers replace parallel bus architectures.

Key features of the EP1SGX40CF672C5 include 3.42 Mbits of TriMatrix embedded RAM, up to 20 transceiver channels supporting serial rates up to 3.125 Gbps, dedicated clock management with up to 12 PLLs, and 1.5V core operation. The 672-pin FineLine BGA package supports high pin density while preserving signal integrity for differential transceiver pairs. The C5 speed grade places this device in Altera's commercial temperature tier, with the device specified for 0C to +85C ambient operation.

Technically, the EP1SGX40CF672C5 uses a 1.5V SRAM-based LUT architecture and is configured via an enhanced configuration device (EPC) or via JTAG. The 3.125 Gbps transceivers support standards such as PCI Express, Serial RapidIO, Gigabit Ethernet, XAUI, and Fibre Channel. A 672-ball FineLine BGA delivers 484 user I/O pins plus transceiver and supply balls, enabling dense PCB designs that minimize trace length on high-speed serial lanes.

Typical applications include multi-gigabit serial backplanes, SONET/SDH framer interfaces, high-speed serial protocol bridging, broadcast video routers, and storage area network switching fabrics. The Stratix GX family is widely deployed in long-lifecycle telecommunications and industrial systems where its mature Quartus II toolchain provides extensive IP libraries and reference designs.

Designers should verify transceiver reference clock distribution and AC-coupling capacitor selection for each serial lane, since compliance with PCI Express and XAUI eye masks depends heavily on board-level signal integrity. Quartus II software version 5.1 or later is required for this device, and PCB stackup must maintain 100-ohm differential impedance for the MGT lanes.

典型應用

EP1SGX40CF672C5 適用於 6 應用s: Multi-Gigabit Serial Backplane, SONET/SDH Framer Interface, Broadcast Video Router, Storage Area Network Switch, Industrial High-Speed Data Acquisition, Wireless Baseband Processing.

🌐

Multi-Gigabit Serial Backplane

The EP1SGX40CF672C5's 20 multi-gigabit transceiver channels operating up to 3.125 Gbps make it well suited for serial backplane switching fabrics in telecom central offices and data-center leaf/spine topologies. Each MGT lane carries XAUI, Serial RapidIO, or PCI Express with 8b/10b encoding, and the 41,250 LE fabric absorbs layer-2 forwarding, buffer management, and protocol encapsulation. The 672-ball FineLine BGA keeps serial lane lengths matched, which is critical for keeping jitter under the 0.35 UI budget of XAUI. Place external AC-coupling capacitors within 200 mils of each transceiver ball, and reference-clock distribution must use a low-jitter clock fanout buffer such as the CDCL6010.

SONET/SDH Framer Interface

The EP1SGX40CF672C5 is widely used in OC-192/STM-64 framer line cards where 16-20 transceivers aggregate 2.488 Gbps optical tributaries. The 12 PLLs provide independent clock synthesis per channel, allowing different line rates to coexist on the same device, while the 3.42 Mbits of TriMatrix RAM store pointer state machines and payload mappings. The C5 commercial speed grade is sufficient for indoor central-office deployments, and Quartus II includes Altera's POS-PHY Level 4 and UTOPIA IV IP cores. Designers should budget 0.5W per active MGT at 3.125 Gbps and use a 12-layer PCB stackup with dedicated transceiver power islands.

Broadcast Video Router

In broadcast SDI/HD-SDI/3G-SDI router chassis the EP1SGX40CF672C5 acts as the crosspoint fabric and re-clocker, replacing discrete FPGA/CPLD arrays. The 20 transceivers accept SMPTE 259M/292M/424M serial streams while the 41,250 LE fabric implements matrix switching up to 256 x 256. TriMatrix RAM holds line buffers for embedded audio (SMPTE 272M/299M) and ancillary data, and the 484 user I/O support GPIO for control and tally. Commercial temperature grade (0C to +85C) fits climate-controlled studios. Pair with the LMH0344 SDI reclocker for cable-equalized inputs.

Storage Area Network Switch

The EP1SGX40CF672C5 is used in 4G/8G Fibre Channel and SATA/SAS storage switches where the 3.125 Gbps transceivers drive SFP+ cages. The 41,250 LE fabric absorbs cut-through FC frame handling, FSPF routing tables, and SAS expander logic, while TriMatrix RAM buffers large frame bursts. The 672-ball FineLine BGA exposes enough general-purpose I/O for SAS wide-port implementations. Quartus II 5.1+ supports the Altera FC and SAS IP cores, and the design migrates cleanly to Stratix IV GX for 8G FC upgrades.

Industrial High-Speed Data Acquisition

Industrial test-and-measurement platforms use the EP1SGX40CF672C5 to capture multi-channel ADC data streams at gigabit rates and pre-process them in fabric DSP blocks before forwarding to host processors. The 3.42 Mbits of TriMatrix RAM plus on-chip multipliers implement FIR filters and FFT engines, while the 20 transceivers accept LVDS or SerDes streams from front-end ADCs. Commercial C5 grade is adequate for indoor industrial cabinets. Designers should validate thermal envelope with the 27 x 27 mm BGA thermal model since the device can dissipate 4-6 W under full MGT load.

Wireless Baseband Processing

In WiMAX and early LTE picocell base stations the EP1SGX40CF672C5 performs baseband modulation/demodulation, channel coding, and CPRI/OBSAI framer termination to the radio unit. The 20 transceivers handle CPRI line rates up to 3.072 Gbps, the 41,250 LE fabric runs Turbo and Viterbi decoders, and the 12 PLLs synthesize the radio clock tree. The C5 commercial temperature range suits indoor picocell enclosures. Plan for ~5 W device power under full load and use a heat-spreader-equipped BGA socket for field-replaceable modules.

What is the EP1SGX40CF672C5?
The EP1SGX40CF672C5 is a member of Altera's first-generation Stratix GX FPGA family that integrates 41,250 logic elements, 3.42 Mbits of embedded TriMatrix RAM, and up to 20 multi-gigabit transceiver channels in a 672-ball FineLine BGA package. According to the Altera Stratix GX device handbook, the device targets high-bandwidth serial interconnect applications such as backplanes and storage fabrics operating up to 3.125 Gbps per lane.
How many transceivers does the EP1SGX40CF672C5 have?
The EP1SGX40CF672C5 supports up to 20 full-duplex multi-gigabit transceiver (MGT) channels, each capable of serial data rates from 622 Mbps up to 3.125 Gbps. This number is the maximum configuration in the EP1SGX40 device; lower-density variants of the family have fewer transceivers. The transceivers support protocols including PCI Express, Serial RapidIO, XAUI, Gigabit Ethernet, and Fibre Channel.
What is the maximum user I/O count on the EP1SGX40CF672C5?
The EP1SGX40CF672C5 provides up to 484 user I/O pins in addition to its transceiver and supply balls within the 672-pin FineLine BGA. According to the device datasheet, the actual usable I/O count depends on the configuration mode and how many pins are reserved for clock inputs, JTAG, and configuration signals. Engineers should consult Pin-Out Files in Quartus II for their specific design.
Where can I buy EP1SGX40CF672C5 and what is the price?
As of 2026-09-07, the EP1SGX40CF672C5 is listed at approximately 285.00 USD per unit at qty 1, with tier breaks to 171.00 USD per unit at qty 1000. Authorized distributors carrying stock include Jotrin, Partstack, and Vyrian; the part is flagged NRND (Not Recommended for New Designs) by Altera, so lead times may extend to 8-12 weeks at some channels.
What is the lead time for EP1SGX40CF672C5?
Lead time for the EP1SGX40CF672C5 as of 2026-09-07 is typically 8-12 weeks through authorized distributors such as Jotrin, because the device is in NRND status. The part is no longer recommended for new designs, so stocking is limited to remaining inventory. For new programs, design teams are advised to migrate to Stratix II GX, Stratix IV GX, or Cyclone IV GX families.
EP1SGX40CF672C5 vs EP1SGX40DF1020C5 - which is better for high-pin-count designs?
The EP1SGX40CF672C5 ships in a 672-ball FineLine BGA with up to 484 user I/O, while the EP1SGX40DF1020C5 uses a 1020-ball BGA and supports the same 40K LE / 20-channel density. Choose the 672-pin variant when board area is at a premium and your I/O count fits within 484 pins; choose the 1020-pin variant when you need additional general-purpose I/O banks or more transceiver channels wired out to balls.
Is there an Intel / Altera equivalent for the EP1SGX40CF672C5?
Yes, the closest Intel/Altera same-package drop-in equivalent is the EP1SGX40CF1020I5 variant in the 1020-ball BGA, which uses the same silicon but exposes additional I/O. Within the same 672-ball FineLine BGA footprint, no direct cross-silicon drop-in is available, but the EP1S60F1508C7 shares the Stratix architecture and is a functional upgrade candidate when migrating within the family.
What is the best drop-in replacement for the EP1SGX40CF672C5?
The best drop-in replacement is the EP1SGX40CF1020C5, which uses the same Stratix GX silicon die but in a larger 1020-ball BGA - it is electrically compatible but requires a different PCB land pattern, so it is not a true pin-to-pin drop-in. For a true pin-to-pin 672-ball drop-in, the EP1SGX25CF672C7 is the only same-footprint Stratix GX option, but it has lower logic density (25K LE vs 41,250 LE) and should be evaluated for design margin.
When should I choose the EP1SGX40CF672C5 over an EP1SGX25 variant?
Choose the EP1SGX40CF672C5 when your design requires 30K+ logic elements, 3+ Mbits of block RAM, and the full 20-channel transceiver complement. The EP1SGX25 family tops out at 25,560 LE and roughly half the RAM, so it fits cost-sensitive designs with lower gate counts. The 40K device also supports more PLLs and clock domains, which matters in multi-rate SONET/SDH or video router fabrics.
Is the EP1SGX40CF672C5 suitable for new designs?
No, Altera has flagged the EP1SGX40CF672C5 as NRND (Not Recommended for New Designs) as of 2026-09-07. For new programs, design teams should evaluate Stratix II GX, Stratix IV GX, or Cyclone IV GX families which offer higher transceiver rates, lower core voltage, and active long-term support. The 40K part remains supported for existing long-lifecycle telecom and industrial customers.
Where to download EP1SGX40CF672C5 datasheet PDF?
The EP1SGX40CF672C5 datasheet is available as a PDF from AllDatasheet at https://www.alldatasheet.com/datasheet-pdf/pdf/530618/ALTERA/EP1SGX40.html and from the FPGAkey catalog at https://www.fpgakey.com/altera-parts/ep1sgx40cf672c5. The Altera/Intel documentation archive also hosts the Stratix GX Device Handbook which contains full pinout tables, transceiver specifications, and reference designs.
Where can I find the EP1SGX40CF672C5 pinout?
The EP1SGX40CF672C5 pinout is documented in the Stratix GX Device Handbook and the device-specific Pin-Out File for the 672-pin FineLine BGA package, both distributed by Altera/Intel. Designers can also load the .qsf into Quartus II and run the Pin Planner to verify per-pin assignments. The 672-ball package uses 27 x 27 mm body with 1.0 mm ball pitch per the Altera package specification.
What is the difference between EP1SGX40CF672C5 and EP1SGX40CF1020C5?
The EP1SGX40CF672C5 uses a 672-ball FineLine BGA, while the EP1SGX40CF1020C5 uses a 1020-ball BGA. Both parts share the same 41,250 LE Stratix GX silicon die and the same 20-channel transceiver capability. The 1020-ball variant exposes additional general-purpose I/O and additional transceiver channel balls for designs that need more wired-out high-speed serial lanes or wider parallel buses.
What are the key specifications of EP1SGX40CF672C5 that engineers should know?
The EP1SGX40CF672C5 contains 41,250 logic elements, 3.42 Mbits of embedded TriMatrix RAM, up to 20 multi-gigabit transceiver channels running up to 3.125 Gbps, up to 12 PLLs, and up to 484 user I/O in a 672-ball FineLine BGA package. The 1.5V core and commercial temperature range (0C to +85C) make it suitable for indoor telecom and industrial deployments. Engineers should plan for EPC-based configuration and Quartus II 5.1+ toolchain support.

選型指南

Choose the EP1SGX40CF672C5 when your design needs 20 multi-gigabit transceiver channels in a 672-ball FineLine BGA and your board space cannot accommodate the 1020-ball variant. The C5 commercial speed grade is adequate for indoor telecom, broadcast, and industrial deployments but should not be used for outdoor or military temperature ranges - select the I5 or I6 industrial grade for those. If your logic and RAM utilization is below 60% of the 41,250 LE / 3.42 Mbit envelope, choose the EP1SGX25CF672C7 instead to save cost. For new programs where lifecycle support matters, evaluate Stratix II GX or Stratix IV GX rather than re-using this NRND silicon.

主要差異化特點

  • Highest transceiver count in 672-ball FineLine BGA within Stratix GX family (對比EP1SGX25CF672C7)
  • Highest-density 672-ball BGA option for long-lifecycle telecom programs (對比EP1SGX40CF1020C5)
  • Mature Quartus II 5.1+ toolchain with extensive IP library (對比Newer Stratix II GX EP1SGX40)

設計說明

Estimated: Use a 12-layer PCB stackup with dedicated transceiver power islands (VCCMGT, VTT, VCCT) routed as solid planes. Maintain 100-ohm differential impedance on MGT pairs and place AC-coupling capacitors within 200 mils of each transceiver ball. Decoupling: 0.1uF X7R at every power pin plus 10uF bulk per power island. Reference-clock traces must be length-matched to within 25 mils and routed on an inner stripline layer with continuous ground reference to keep jitter under 0.35 UI.

Estimated: The EP1SGX40CF672C5 can dissipate 4-6 W under full MGT load (0.5 W per active 3.125 Gbps transceiver plus core power at 1.5V). The 27 x 27 mm FineLine BGA thermal resistance theta_JA is approximately 12 C/W with 4-layer JEDEC test board, which yields a 72 C junction temperature rise above 85 C ambient - exceeding the C5 commercial spec. For full-load operation, mount a heat spreader or use 12-layer boards with 1 oz copper inner planes and thermal vias under the center balls.

Do not substitute the EPC16 configuration device for the older EPC8 or EPC2 - the EP1SGX40CF672C5 requires the enhanced configuration device family (EPC16, EPC64, EPC128) and will not configure from legacy EPC1/EPC2 chains. The C5 speed grade must be selected explicitly in Quartus II device selection; using C6 or C7 defaults will give incorrect timing analysis. JTAG chain ordering should place the EPC device between TDI and the FPGA for in-system programming safety.

Reference-clock distribution for the 20 MGT channels must use a low-jitter fanout buffer such as the CDCL6010 or AD9516. Crosstalk between adjacent MGT pairs exceeds -25 dB without proper spacing, so enforce at least 4x dielectric spacing between differential pairs and stitch vias every 200 mils along the ground return path. The reference-clock PCB traces should be 50-ohm single-ended controlled impedance; place a 49.9 ohm 1% termination at the receiver end and avoid stubs by using 0402 or smaller series resistor footprints.
