System Design Information
This section provides electrical and thermal design recommendations for successful application of the
MPC755.
8.1
PLL Configuration
The MPC755 PLL is configured by the PLL_CFG[0:3] signals. For a given SYSCLK (bus) frequency, the
PLL configuration signals set the internal CPU and VCO frequency of operation. These must be chosen
such that they comply with Table 8. Table 16 shows the valid configurations of these signals and an
example illustrating the core and VCO frequencies resulting from various PLL configurations and
example bus frequencies. In this example, shaded cells represent settings that, for a given SYSCLK
frequency, result in core and/or VCO frequencies that do not comply with the 400-MHz column in Table 8.
