Product Introduction:5SGXMA3H3F35C4G Product Introduction

The 5SGXMA3H3F35C4G is a Stratix V GX FPGA from Intel (formerly Altera), fabricated on a 28nm process. With 340K logic elements, 22.92 Mbits embedded memory, and 256 DSP blocks, this device delivers exceptional performance for bandwidth-centric applications. The integrated transceivers support data rates up to 14.1 Gbps with built-in PCIe Gen3 hard IP, making it ideal for 40G/100G networking, high-performance DSP, and communications infrastructure. The -3 speed grade provides the highest core performance in the commercial temperature range.

Working Principle:5SGXMA3H3F35C4G Working Principle

The 5SGXMA3H3F35C4G Stratix V GX FPGA operates as a reconfigurable logic device with integrated high-speed transceivers. The core fabric consists of Adaptive Logic Modules (ALMs) that can implement any combinational or sequential logic function. Each ALM contains lookup tables (LUTs), carry chains, and registers for efficient arithmetic and logic operations. The 36 integrated transceivers implement the physical layer of high-speed serial protocols, performing parallel-to-serial conversion, clock data recovery, and 8B/10B or 64B/66B encoding/decoding. The PCIe Gen3 hard IP block handles the complete protocol stack including transaction, data link, and physical layers. Variable precision DSP blocks provide dedicated 18×18 or 27×27 multiplier-accumulator units for efficient FIR filtering and FFT computation. Programmable power technology allows unused ALMs to operate in low-power mode, reducing static power consumption by up to 40%.
