4.5 AC Characteristics
Table 4-4 through Table 4-9 list the AC character-
istics including output delays, input setup require-
ments, input hold requirements and output float
delays. These measurements are based on the
measurement points identified in Figure 4-1 . The
rising clock edge reference level VREF , and other
reference levels are shown in Table 4-3 below for
the STPC Consumer. Input or output signals must
cross these levels during testing.
Figure 4-1 shows output delay (A and B) and input
setup and hold times (C and D). Input setup and
hold times (C and D) are specified minimums, de-
fining the smallest acceptable sampling window a
synchronous input signal must be stable for cor-
rect operation.
Note: Refer to Figure 4-1.
