Electrical and Thermal Characteristics
2.4
The following sections include illustrations and tables of clock diagrams, signals, and CPM outputs and
inputs for the 66 MHz MPC826xA device. Note that AC timings are based on a 50-pf load. Typical output
buffer impedances are shown in
Table 7

Notes:
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.
