What is a Stratix II GX FPGA? 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 such as transceivers, multipliers, and memory blocks. The 'Stratix' family sits in Intel's high-end FPGA portfolio, optimized for performance, density, and high-speed serial I/O. Within the taxonomy: FPGA -> programmable logic device -> ASIC-class reconfigurable logic -> semiconductor. FPGAs are used when time-to-market, hardware reconfigurability, or parallel processing throughput outweigh the per-unit cost advantages of a fixed-function ASIC.
Key features of the EP2SGX90EF35C5NGA include up to 12 full-duplex transceiver channels supporting protocols such as PCI Express Gen1, XAUI, Serial RapidIO, and CEI-6G, 8 PLLs with on-chip termination calibration, and dedicated DSP blocks delivering up to 192 GMACS performance. The 1.2 V core supply with on-chip voltage regulation simplifies power-rail design, while the 1152-pin FineLine BGA (35 mm body) provides a thermally enhanced land pattern with a large exposed die paddle.
Architecturally, the device combines a logic fabric built from adaptive logic modules (ALMs) with hard PCI Express, XAUI, and external memory interface IP, allowing engineers to drop in complete protocol controllers without consuming FPGA fabric. The 90 nm process and 1.2 V core offer a balance of static power and performance for telecom backplane and high-end test equipment applications.
Typical applications include high-end test and measurement instrumentation, telecom backplane aggregation, broadcast video processing, ASIC prototyping, and DSP co-processing cards. The integrated 6.375 Gbps transceivers make the device especially relevant for legacy 10 Gbps Ethernet and RapidIO line-card designs.
When designing with this FPGA, ensure the PCB land pattern matches the 35 mm FineLine BGA recommended by Intel. Thermal management must account for the 1.2 V core current draw at high toggle rates; a minimum 8-layer stack-up with continuous ground and power planes is recommended. The EPC (Enhanced Configuration Device) classification in the part number indicates this device works with the legacy Altera EPC configuration memory family, so the companion configuration PROM must be ordered from the same product tree.

典型應用
EP2SGX90EF35C5NGA 適用於 6 應用s: Telecom Backplane Aggregation, High-End Test and Measurement Instrumentation, Broadcast Video Processing, ASIC Prototyping, DSP Co-Processing Cards, Legacy Industrial Control and HMI.
Telecom Backplane Aggregation
The EP2SGX90EF35C5NGA's 12 multi-gigabit transceiver channels up to 6.375 Gbps directly support XAUI, Serial RapidIO, and CEI-6G aggregation on telecom line cards. The 90K logic elements handle packet inspection and traffic management fabric, while 4.5 Mbits of embedded RAM buffers cells at line rate. With 192 18x18 multipliers available as DSP blocks, the device performs wire-speed QoS classification and encryption. In a typical deployment, the FPGA sits between a network processor and the backplane SERDES, replacing multiple discrete PHY ICs with a single integrated solution and reducing PCB area by 30-40%.
推薦
High-End Test and Measurement Instrumentation
The EP2SGX90EF35C5NGA fits the high-throughput signal processing needs of oscilloscope, BERT, and protocol-analyzer platforms. The 192 DSP blocks deliver 192 GMACS for FFT-based spectrum analysis and real-time FIR filtering, while the 12 transceivers accept 6.375 Gbps data streams from high-speed ADCs and DACs without external clock-data-recovery circuitry. Engineers often pair the device with 1 Gsample/s ADC front-ends, using the FPGA to perform real-time triggering and pattern recognition. The 35 mm FineLine BGA's thermally enhanced land pattern supports continuous operation in benchtop instruments with moderate airflow.
推薦
Broadcast Video Processing
Broadcast video routers and format converters require the EP2SGX90EF35C5NGA's combination of high logic density and multi-gigabit serial I/O for SDI-over-IP and 3G-SDI multiplexing. The 12 transceivers accept SMPTE 424M (3G-SDI) inputs, while the 90K logic elements perform color-space conversion, scaling, and frame-rate adaptation. The 4.5 Mbit embedded RAM acts as a line buffer, eliminating the need for external DDR in some single-stream designs. A typical 16x16 router using one EP2SGX90EF35C5NGA can replace three to four legacy SDI crosspoint ICs.
推薦
ASIC Prototyping
The EP2SGX90EF35C5NGA serves as a target for ASIC RTL prototyping in the 90K-equivalent-gate range, allowing verification engineers to validate designs at near-ASIC clock rates before tape-out. The 90 nm process and 1.2 V core deliver predictable timing correlation to production ASIC libraries, while the 8 PLLs and 12 transceivers allow designers to prototype SerDes-heavy ASICs with the same silicon used in production. Quartus II's TimeQuest SDC support and the Stratix II GX's rich debug infrastructure (SignalTap II, Logic Analyzer interface) make it a strong choice for hardware/software co-verification.
推薦
DSP Co-Processing Cards
The EP2SGX90EF35C5NGA's 192 dedicated 18x18 multipliers deliver 192 GMACS of DSP throughput, making it well-suited for radar, sonar, and software-defined-radio co-processing cards. The 12 transceivers accept digitized RF data at up to 6.375 Gbps from high-speed ADCs, while the 90K logic elements implement the surrounding control and DMA fabric. In a typical radar pre-processor, the device performs pulse compression and Doppler filtering directly on the ADC output, reducing host CPU load by 80-90% and enabling real-time situational awareness.
推薦
Legacy Industrial Control and HMI
Industrial automation platforms integrate the EP2SGX90EF35C5NGA as a high-speed I/O concentrator that aggregates PROFINET, EtherCAT, and CC-Link frames on a single board. The 12 transceivers provide dedicated channels for time-sensitive industrial Ethernet protocols, while the 90K logic elements handle the protocol stacks and motion-control loops. The commercial 0-85C temperature range suits factory-floor enclosure environments with filtered airflow, and the EPC configuration family allows hot-swap firmware updates via standard JTAG.

主要差異化特點
- Active commercial production tail through the C5 speed grade (對比EP2SGX90EF35C4NGA)

設計說明
The 1152-pin FineLine BGA (F35) at 1.0 mm ball pitch requires a minimum 8-layer PCB stack-up with 0.5 oz copper on outer layers and 1 oz on inner power/ground planes. Use of a microvia or HDI process is recommended for the BGA break-out; through-via fanout alone is rarely possible at 1.0 mm pitch without signal-integrity loss. Reference the Altera AN 548 pin connection guidelines for the F35 package and validate escape routing with field-solver simulation before tape-out.
Estimated: at full logic utilization (80%) and 100% toggle rate on I/O, the EP2SGX90EF35C5NGA draws approximately 15-20 W from the 1.2 V core rail. With a 35 mm BGA junction-to-ambient thermal resistance (theta_JA) of approximately 8-10 C/W for a 4-layer JEDEC test board, a heatsink is required for continuous operation above 70C ambient. Use a thermal interface material rated for 5-7 C/W or better, and place a thermocouple near the center of the BGA for in-situ monitoring.
Do not apply power to the 1.2 V core rail before the 2.5 V and 3.3 V auxiliary supplies are stable. The Stratix II GX has specific power-sequencing requirements documented in the device handbook; out-of-order ramp can cause long-term reliability degradation or latch-up. Use a power management IC with programmable sequencing or a discrete FET-based sequencer for prototype builds.
