2.2.11. PLL Reconfiguration and Dynamic Phase Shift

Stratix® 10 devices support PLL reconfiguration and dynamic phase shift with the following features:

  • PLL reconfiguration—I/O PLL and fPLL are able to reconfigure the M, N, and C counters. Only the fPLL supports reconfiguration of the fractional settings.
  • Dynamic phase shift—Only the I/O PLL can perform positive or negative phase shift. Able to shift multiple phase steps each time, where one phase step is equal to 1/8 of the VCO period.
