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 MHz 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.

Values do not include I/O. Add the following estimates for active I/O based on the following bus speeds:
66.7 MHz = 0.45 W (nominal), 0.5 W (maximum)
83.3 MHz = 0.5W (nominal), 0.6 W (maximum)
100 MHz = 0.6 W (nominal), 0.7 W (maximum)
