  1. Overclocking is only supported in 100 GbE (with FRX_CORE_CLK and FTX_CORE_CLK running at 706 MHz, and the FRX_SERDES_CLK running at 353 MHz) by faster speed grade devices (-3H, -2M, -2L).
  2. The ALT_SERDES_CLKs run at half the speed of the primary SERDES_CLK. See Versal Devices Integrated 100G Multirate Ethernet MAC (MRMAC) LogiCORE IP Product Guide (PG314) for more information.
