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 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 this table.

CPM AC Characteristics
This table lists CPM output characteristics.
Table 9. Output Buffer Impedances1
1 These are typical values at 65° C. Impedance may vary by ±25% with
process and temperature.

Table 10. 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.
