Maximum achievable global clock frequency depends on span of the clock tree. The following table lists both the maximum switching frequencies for each buffer type and the maximum achievable frequency for the worst-case clock route spanning the entire device. Refer to the Versal Adaptive SoC Clocking Resources Architecture Manual (AM003) for more information.
FMAX

Maximum frequency of global clock switching characteristics for:

  • Global clock tree (BUFG) including BUFGCTRL and MBUFGCTRL
  • Global clock buffer with input divide capability (BUFGCE_DIV and MBUFGCE_DIV)
  • Global clock buffer with clock enable (BUFGCE and MBUFGE)
  • Global clock buffer for the processing system (BUFG_PS and MBUFG_PS)
All 1150 1150 1070 984 800 680 MHz
Maximum frequency of global clock switching characteristics for GTYP or GTM clock buffer with clock enable and clock input divide capability (BUFG_GT and MBUFG_GT) All 1150 1150 1070 984 1000 680 MHz
FMAX

Maximum frequency of global clock switching characteristics for the worst-case clock route spanning the entire device:
