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.
