PS8925 _ PCI Express® Gen 4 16Gbps 4-Lane Retimer

 Parade PS8925 是一款4 通道雙向Retimer（使用總共 8 個數據通道），支持 PCIe® (PCI Express®) Gen 4應用，傳輸速率最高可達 16Gbps。

 PS8925具有低延遲能力，是workstations和Server等應用的理想選擇。

作為PCIe Gen4 應用線路中的 Retimer，PS8925 消除了可能因為 Cross-Talking或系統雜訊引起錯誤的信號失真。並且可以補償PCIe協會規範內之PCIe Gen4應用的損耗 (扣除 CPU Package損耗5dB加上PS8925的Package損耗為3dB 後的20dB)，產品應用中可能造成PCIe Gen4信號損耗因素包括 PCIe Cable、PCB traces和connector。

Parade PS8925增強了PCIe Gen4數據傳輸的可靠性並可支援更長的 PCIe Cable或PCB走線，從而實現系統可擴展性。
