Electrical and Thermal Characteristics
5.2
This section provides the AC electrical characteristics for the MPC7457. After fabrication, functional parts
are sorted by maximum processor core frequency as shown in Section 1.5.2.1, “Clock AC Specifications,”
and tested for conformance to the AC specifications for that frequency. The processor core frequency is
determined by the bus (SYSCLK) frequency and the settings of the PLL_CFG[0:4] signals. Parts are sold
by maximum processor core frequency; see Section 1.11, “Ordering Information.”
5.2.1
Table 8
operating frequencies of the devices. The maximum system bus frequency, f
considered a practical maximum in a typical single-processor system. The actual maximum SYSCLK
frequency for any application of the MPC7457 will be a function of the AC timings of the MPC7457, the
AC timings for the system controller, bus loading, printed-circuit board topology, trace lengths, and so
forth, and may be less than the value given in
spectrum clock generators, see
Sources.” PLL configuration and bus-to-core multiplier information is found in
