Arria®GX FPGA是Altera帶有收發器的中端FPGA系列。其收發器速率高達3.125 Gbps，您可以利用它來連接支持PCI Express、千兆以太網、Serial RapidIO、SDI等協議的現有模塊和器件。Arria GX FPGA含有Altera的第四代收發器，確保您的設計具有優異的信號完整性。

同類最佳的信號完整性

Arria GX收發器基于最初為Stratix II GX FPGA系列開發而大獲成功的技術之上。所有系列均采用90nm工藝技術生產，使用相同的物理介質附加(PMA)電路。Arria GX還含有Stratix II GX FPGA物理編碼子層(PCS)的子集。結合倒裝焊封裝，這些特性在低成本收發器FPGA中實現了同類最佳的信號完整性。

獲得大獎的軟件工具和IP，提高了效能

Altera的Quartus II 和SOPCBuilder幫助您迅速輕松地將設計構思實現為最終產品。Quartus II 以最快的編譯時間和精確的結果幫助您提高效能。利用SOPCBuilder，您可以在簡單直觀的圖形界面下，無縫連接知識產權(IP)模塊。此外，Timequest是強大的ASIC功能時序分析器，支持業界標準Synopsys設計約束(SDC)格式。

世界范圍內的高速專家網絡

當器件需要連接高速接口時，您可以咨詢Altera的系統級專家們，通過MySupport在線接觸專家，或者聯系當地的現場應用工程師組。每一地區支持中心(RSC)的高速串行接口系統專家在MySupport上回答您提出的問題。Altera在北美設立了RSC應用工程師組。
