Notes to Table:

  1. For more details, refer to the Clock Networks and PLL chapter of the respective device family handbook.
  2. PLL_5 and PLL_6 of Arria II GX devices do not have dedicated clock outputs.
  3. The same PLL clock outputs drives three single-ended or three differential I/O pairs, which are only supported in PLL_1 and PLL_3 of the EP2AGX95, EP2AGX125, EP2AGX190, and EP2AGX260 devices.
