譜瑞科技Parade Technologies LTD.,推出了專為伺服器市場開發的PS8926 PCI-E 4.0的 Retimer時序芯片, PS8926已完成企業等級的網路與儲存設備系統嚴格的測試與驗證,並已在2021年正式量產.目前“譜瑞科技是目前業界第一個可提供量產的PCI Express Gen4時序重整晶片的供應商,能以4通道的PS8925以及16通道的PS8926/PS8926A 涵蓋所有的PCIe Gen4擴充匯流排組合,另外普瑞科技也正著手準備PCI Express Gen5的時序重整晶片產品以因應下個世代的產品.
PS8926產品特點,支援高達16對雙向的PCI-E 4.0傳輸通道,其採用32條以16Gbps傳輸速率運行的高速線路。而PS8926包含了16個雙向傳輸通道,更支援×16, ×8,x4 以及X2的PCI-E line的拆分組合。 不只PS8926A,譜瑞科技的PCI-E 4.0系列產品均支持譜瑞獨家的PABR(Protocol Aware Bit-level Retimer,可識別協定位元等級時序重整)技術,只有2奈秒的傳輸延遲, 相對其他支援PCI Express Gen4標準的時序重整芯片能提供的43ns延遲,更能增加資料傳輸量且大幅度的減少存取時間。
