Notes:
4. C1 = 35 pF.
5. The fMAX values represent the highest frequency for pipeline data.
6. This parameter is measured with a positive-edge-triggered clock at the register. For negative-edge clocking, the tACH and tACL parameter must be swapped.
7. This parameter is measured with a 16-bit counter programmed into each LAB.
8. C1 = 5 pF.
