Typical Applications
EP1SGX10DF672C7 is suitable for 6 applications: PCI Express Endpoint / Root Complex, Gigabit Ethernet Aggregation / Switching Line Cards, Serial RapidIO Baseband Processing, High-Speed Serial Protocol Bridge / ASIC Prototype, Radar / Ultrasound DSP Preprocessing, Industrial Test & Measurement Instrumentation.
PCI Express Endpoint / Root Complex
The EP1SGX10DF672C7 is well suited to PCI Express endpoint and root complex designs because it integrates up to 20 hardened 3.125 Gbps transceiver channels that natively support the PCIe x1 and x4 physical layer. The transceiver PMA handles 8B/10B encoding, comma alignment, and clock-data recovery, while the soft PCS implements the transaction and data link layers. Using the ALT2GXB megafunction in Quartus II, engineers can build a complete PCIe x4 endpoint in approximately 3,000 logic elements, leaving the remaining 7,500 LEs for user logic. For boards targeting 2.5 GT/s PCIe Gen 1 throughput with minimal board BOM, the FBGA-672 device provides the highest logic count in the EP1SGX10 family while exposing the maximum transceiver count.
Recommended
Gigabit Ethernet Aggregation / Switching Line Cards
Telecom line cards aggregating multiple Gigabit Ethernet links into a backplane fabric benefit from the EP1SGX10DF672C7's integrated 1000BASE-X PCS support. Each transceiver implements the 8B/10B physical coding sublayer with rate adaptation, while soft logic can build the MAC, link aggregation, and switching table. The device's 920 kbit embedded RAM buffers packets efficiently, and the 362 user I/O pins accommodate multiple GMII/RGMII interfaces plus SGMII bridges. Compared with discrete PHY + ASSP solutions, this single-chip approach reduces board area by approximately 40% and simplifies thermal design because all serial channels are uniformly clocked from a single PLL tree.
Recommended
Serial RapidIO Baseband Processing
Wireless baseband DSP cards use the EP1SGX10DF672C7 to bridge Serial RapidIO (sRIO) links to DSP clusters such as TI TMS320C6000 series. The embedded 3.125 Gbps transceivers map directly to the sRIO physical specification, and the device's 10,570 logic elements provide ample fabric for the sRIO logical layer, error correction, and DSP preprocessing (FFT, channelization, FEC). The 920 kbit block RAM holds frame descriptors and circular buffers for sustained 2 Gbps throughput, while the 362 user I/O pins interface to external DDR-2 and LVDS links. Engineers can build complete sRIO-to-DSP bridges with under 30ns backplane latency.
Recommended
High-Speed Serial Protocol Bridge / ASIC Prototype
For ASIC replacement or pre-silicon prototyping of custom serial protocols (XAUI, Aurora, custom 8B/10B), the EP1SGX10DF672C7 provides the flexibility to implement both ends of the link in a single device family. Each transceiver channel can be configured independently for different data rates and protocols, making the device ideal for bridging between XAUI, SGMII, and PCIe in protocol-converter applications. The abundant 362 user I/O pins accommodate parallel LVDS side interfaces to legacy ASICs, and the large embedded RAM enables packet buffering across the protocol bridge.
Recommended
Radar / Ultrasound DSP Preprocessing
Medical imaging and defense radar systems use the EP1SGX10DF672C7 for high-speed DSP preprocessing of ADC sample streams before forwarding to host processors. The integrated multiplier/DSP blocks implement FIR filters and FFT butterflies at full sample rate, while the transceivers stream processed data to downstream FPGAs or DSPs via Aurora or Serial RapidIO. The 920 kbit block RAM holds complex FFT twiddle tables and intermediate frame buffers. Compared with discrete DSP processor arrays, a single EP1SGX10DF672C7 reduces power per FFT by 3-5x and enables deterministic latency for phase-sensitive beamforming.
Recommended
Industrial Test & Measurement Instrumentation
Bench-top test equipment such as protocol analyzers, BERT (bit error rate testers), and logic analyzers leverage the EP1SGX10DF672C7 for simultaneous generation and analysis of multi-gigabit serial traffic. Each channel can be looped back for self-test, and the embedded RAM captures long PRBS patterns for jitter compliance testing. The 362 user I/O pins drive LCD/TFT displays and front-panel controls, while the 10,570 logic elements host custom measurement firmware. The commercial temperature grade (0 C to 85 C) is appropriate for laboratory environments.

Key Differentiators
- Highest logic count in the EP1SGX10 family with full transceiver count in same package (vs EP1SGX10DF672C7N)
- Integrated 3.125 Gbps transceivers vs none (vs EP1SGX10CF672C7)
- Drop-in compatible with Stratix II GX successor for migration path (vs EP2SGX30DF672I4)
Design Notes
The FBGA-672 package uses a 1.0 mm ball pitch on a 33 x 33 mm body, which requires microvia PCB technology (laser-drilled vias with 0.1 mm/0.2 mm capture pads) or via-in-pad construction. Standard 0.3 mm mechanical drills cannot achieve the required pad-to-pad pitch. Plan PCB stackup for at least 8 signal layers with stripline routing for high-speed transceiver channels; allocate dedicated ground reference planes beneath the TX/RX differential pairs. Decoupling must include 0402-size 0.1 uF X7R ceramics within 2 mm of each power ball, plus bulk 22 uF tantalum or polymer capacitors on each VCC/GND pair.
Transceiver channels must be routed as 100 ohm differential pairs with intra-pair skew below 1 ps (approximately 150 um length matching at FR4). Use microstrip with controlled impedance (Zo = 50 ohm single-ended, 100 ohm differential) on top layers and avoid crossing reference plane splits. The reference clock inputs (REFCLK_P/N) require 100 ohm differential routing and isolated from data lanes by at least 3H spacing (where H is dielectric height to nearest reference plane). Use IBIS-AMI models from Altera to validate channel loss budget before tape-out.
Estimated: at full utilization (10,570 LEs @ 70% toggle rate, all 20 transceivers active at 3.125 Gbps), the EP1SGX10DF672C7 dissipates approximately 6-9 W. With theta_JA of approximately 18 C / W on the FBGA-672 (typical per Stratix GX family datasheet), junction temperature rise above ambient is 108-162 C. Adequate airflow (200 LFM minimum) or a heatsink is required; do not operate continuously at maximum junction temperature. The package center-ball thermal pad must be soldered to a continuous copper pour on the top layer with thermal vias to inner ground planes.
Do not attempt to migrate from EP1SGX10DF672C7 to EP2SGX30DF672I4 without re-running full timing closure - the Stratix II architecture uses ALM (Adaptive Logic Module) instead of Stratix LE, so existing RTL must be re-synthesized. Configuration bitstreams are not compatible between Stratix and Stratix II families. JTAG chain order changes between packages - verify BSDL files before using boundary-scan. Finally, ensure that all transceiver channels that are NOT used have their TX pins tied to a known logic level and powered down via the Quartus II device configuration to reduce EMI and power consumption.
Compliance Information
EP1SGX10DF672C7 is the standard SnPb terminal finish variant; EP1SGX10DF672C7N is the Pb-free / RoHS-compliant variant. RoHS status not explicitly stated in the Verified Web Data excerpts - field set to 'unknown'. AEC-Q100 is not applicable for FPGAs operating in commercial temperature grade (0 C to 85 C).
