      AC Electrical Characteristics
      This section provides the AC electrical characteristics for the MPC7448. After fabrication, functional parts
      are sorted by maximum processor core frequency as shown in Section 5.2.1, “Clock AC Specifications,”
      and tested for conformance to the AC specifications for that frequency. The processor core frequency,
      determined by the bus (SYSCLK) frequency and the settings of the PLL_CFG[0:5] signals, can be
      dynamically modified using dynamic frequency switching (DFS). Parts are sold by maximum processor
      core frequency; see Section 11, “Part Numbering and Marking,for information on ordering parts. DFS is
      5.2.1
      Clock AC Specifications
      Table 8 provides the clock AC timing specifications as defined in Figure 3 and represents the tested
      operating frequencies of the devices. The maximum system bus frequency, fSYSCLK, given in Table 8, is
      considered a practical maximum in a typical single-processor system. This does not exclude
      multi-processor systems, but these typically require considerably more design effort to achieve the
      maximum rated bus frequency. The actual maximum SYSCLK frequency for any application of the
      MPC7448 will be a function of the AC timings of the microprocessor(s), the AC timings for the system
      controller, bus loading, circuit board topology, trace lengths, and so forth, and may be less than the value
      given in Table 8.
