without feedback (see Figure 3)
In this mode, data is presented at the input to the flip-flop and clocked through to the Q output with no feedback.
Under this condition, the clock period is limited by the sum of the data setup time and the data hold time (t

However, the minimum fmax is determined by the minimum clock period (t

with internal feedback (see Figure 4)
This configuration is most popular in counters and on-chip state-machine designs. The flip-flop inputs are
defined by the device inputs and flip-flop outputs. Under this condition, the period is limited by the internal delay
from the flip-flop outputs through the internal feedback and logic array to the inputs of the next flip-flop.
Thus, fmaxwith internal feedback
