AC ELECTRICAL SPECIFICATIONS DEFINITIONS •
The AC specifications presented consist of output delays, input setup and
hold times, and signal skew times. All signals are specified relative to an
appropriate edge of the MC68030 clock input and, possibly, relative to one
or more other signals.
The measurement of the AC specifications is defined by the waveforms in
Figure 1. To test the parameters guaranteed by MQtorola, inputs must be
driven to the voltage levels •specified in~ Figure 1. Outputs of the MC68030
are specifiedwith minimum.and/or maximum limits, as appropriate, and are
measured as shown. Inputs to the MC68030 are specified with minimum and,
as appropriate, maximum setup and hold times, and are measured asshown.
Finally, the measurements for signal-to-signal specifications are also shown.
Note that the testing levels used to verify conformance of the MC68030 to
the AC specifications:does ~ not affect the guaranteed DC operation of the
device as specified in the DC electrical characteristics.
