4.3.1.3. PLL Reconfig Intel FPGA IP Core

The PLL Reconfig Intel FPGA IP core facilitates dynamic real-time reconfiguration of PLLs in Intel FPGAs.

Use the IP core to update the output clock frequency, PLL bandwidth in real-time, without reconfiguring the entire FPGA.

You can run this IP core at 100 MHz in Stratix V devices. In Arria V devices, you need to run at 75 MHz for timing closure. To simplify clocking in Arria V devices, the entire management clock domain is capped at 75 MHz.
