TS68020
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
TS68020 clock input and, possibly, relative to one or more other signals.
The measurement of the AC specifications is defined by the waveforms in Figure 12. In
order to test the parameters guaranteed by Atmel, inputs must be driven to the voltage
levels specified in Figure 12. Outputs of the TS68020 are specified with minimum and/or
maximum limits, as appropriate, and are measured as shown. Inputs to the TS68020
are specified with minimum and, as appropriate, maximum setup and hold times, and
are measurement as shown. Finally, the measurements for signal-to-signal specification
are also shown.
Note that the testing levels used to verify conformance of the TS68020 to the AC speci-
fications does not affect the guaranteed DC operation of the device as specified in the
DC electrical characteristics.
