Table 17: I/O Input Register Cell Timing
Parameter
Value
Min Max
Input register setup time: time the synchronous input of the flip-flop must be stable
before the active clock edge
2.15 ns
-
Input register hold time: time the synchronous input of the flip-flop must be stable after
the active clock edge
0 ns
-
Input register clock-to-out: time taken by the flip-flop to output after the active clock edge - 0.3 ns
Input register reset delay: time between when the flip-flop is “reset”(low) and when the
output is consequently “reset” (low)
-
0.82 ns
Input register clock enable setup time: time “enable” must be stable before the active
clock edge
0.4 ns
-
Input register clock enable hold time: time “enable” must be stable after the active clock
edge
0 ns
