Hello,
We dont have the refclk impedance value for Agilex 7 R-tile. May I know why you need this parameter?

芯片型号为AGIB027R29A1E2VC,R-Tile的15A和15C用作PCIE接口(RC),通过MCIO线缆连接NVMe SSD,对应R-Tile的15A和15C的PCIE参考时钟输入阻抗能否接受85Ω?
NVMe SSD的PCIe接口为Gen,对应的阻抗为85Ω,选择的MCIO线缆阻抗也为85Ω,为保证阻抗的连续性,计划参考时钟的输入也用85Ω。
同理,对于R-Tile 14C用作PCIE Gen5接金手指,对应的输入参考时钟是否也可以支持85Ω?
