6.1. Clocking Scheme

To verifying the clocking scheme, follow these steps:

  1. Check that the frame and link clock frequency settings are correct in the IOPLL Intel® FPGA IP.
  2. Check the device clock frequency at the FPGA and converter.
  3. For Subclass 1, check the SYSREF pulse frequency.
  4. Check the management clock frequency.
