The maximum supported clock frequency is 100 MHz if the PCIe hard IP block is enabled or 125 MHz if the PCIe hard IP block is not
enabled.

(39)
To support data rates lower than the minimum specification through oversampling, use the CDR in LTR mode only.
The device cannot tolerate prolonged operation at this absolute maximum.
