Note:
  1. Select the optimum PLD clock frequency to achieve maximum bandwidth. Refer to the Simple Packing Data Width and Optimum PLD Clock Frequency table for more details on the PLD clock frequencies.
  2. Higher than the optimum PLD clock frequency is allowed for some of the Hard IP modes above provided that the timing requirements can be met.
