Figure 27. Synchronous Reset Operation in DR Mode, 1:4 ratio, 1GHz (Full Speed) – TIMINGS
Note: The clock edge to which the reset applies is the one identified by the arrow.
If the reset rising edge had occurred in the second allowed window, the reset would have been effective on the third clock rising edge (not
represented, on the right of the edge represented with the arrow).

Note: The clock edge to which the reset applies is the one identified by the arrow.
If the reset rising edge had occurred in the second allowed window, the reset would have been effective on the fourth clock
rising edge (last clock rising edge, on the right of the edge represented with the arrow).
This case is the most critical one with only a 300 ps window for the reset.
