AC Electrical Characteristics
6 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

On all other revisions, impedance value is selected through the SIUMCR[20,21]. Refer to the MPC8280
PowerQUICC II Family Reference Manual.
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)
These are typical values at 65° C. Impedance may vary by ±25% with process and temperature.
On silicon revision 0.0 (mask #: 0K49M), selectable impedance is not available. Impedance is set at 45 Ω.
