A.5 T2081 Signal Differences
SerDes 2 signals described in Signals Overview are not supported on T2081.
A.6 SerDes Assignments
The following notation conventions are used in the table:
• XFIm indicates XFI (1 lane @10.3125 Gbps), “m” indicates MAC on the Frame Manager. For example, “XFI9”
indicates XFI using MAC 9.
• SGMII notation :
• sgm means SGMII @ 1.25 Gbps where “m” indicates which MAC on the Frame Manager. For example, “SG3”
indicates SGMII for MAC 3 at 1.25 Gbps.
• sgm means SGMII @3.125Gbps where “m” indicates which MAC on the Frame Manager. For example, “SG3”
indicates SGMII for MAC 3 at 3.25 Gbps.
• PCIe notation :
• PCIem is PCIe @ 5/2.5 Gbps, m indicates the PCIe controller number.
• PCIem is PCIe @ 8/5/2.5 Gbps, m indicates the PCIe controller number.
• Per lane PLL mapping: 1-PLL1, 2-PLL2
