Data rates above 6.5536 Gbps up to 10.3125 Gbps, such as 10GBASE-R, are supported through the soft PCS.
PCIe Gen2 is supported only through the PCIe hard IP.

22
XAUI is supported through the soft PCS.
The 0.27 Gbps data rate is supported using oversampling user logic that you must implement in the FPGA
fabric.
The GPON standard does not support burst mode.
