AC Electrical Characteristics
The following sections include illustrations and tables of clock diagrams, signals, and CPM outputs and
inputs for 66.67-/83.33-/100-/133-MHz MPC8272 devices. Note that AC timings are based on a 50-pf load
for MAX Delay and 10-pf load for MIN delay. Typical output buffer impedances are shown in Table 8.

Output specifications are measured from the 50% level of the rising edge of CLKIN to the 50% level of the signal. Timings are
measured at the pin.
