4.5 AC CHARACTERISTICS

Table 4-4 through Table 4-8 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 and

Figure 4-2. The rising clock edge reference level

VREF , and other reference levels are shown in

Table 4-3 below for the STPC Client. Input or out-

put 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.
