System Design Information
This section provides electrical and thermal design recommendations for successful application of the MPC7410.
8.1 PLL Configuration
The MPC7410 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. The PLL configuration for the
MPC7410 is shown in Table 13 for example 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 minimum and
maximum core frequencies listed in Table 8.
