Electrical and Thermal Characteristics

AC Electrical Characteristics
The following sections include illustrations and tables of clock diagrams, signals, and CPM outputs and
inputs for the 66 MHz MPC8260 device. Note that AC timings are based on a 50-pf load. Typical output
buffer impedances are shown in Table 6.
Table 7 lists CPM output characteristics.
Table 8 lists CPM input characteristics.
NOTE: Rise/Fall Time on CPM Input Pins
It is recommended that the rise/fall time on CPM input pins should not
exceed 5 ns. This should be enforced especially on clock signals. Rise time
refers to signal transitions from 10% to 90% of VCC; fall time refers to
transitions from 90% to 10% of VCC.
Table 6. Output Buffer Impedances1
1 These are typical values at 65° C. The impedance
may vary by ±25% with process and temperature.

Table 7. AC Characteristics for CPM Outputs1
1 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.
