45 / 64 page  MPC7455 RISC Microprocessor Hardware Specifications, Rev. 4.1 Freescale Semiconductor 45 System Design Information 8.6 Substrate Capacitors for the MPC7455, 483 CBGA Figure 23 shows the connectivity of the substrate capacitor pads for the MPC7455, 483 CBGA. All capacitors are 100 nF. Figure 23. Substrate Bypass Capacitors for the MPC7455, 483 CBGA 9 System Design Information This section provides system and thermal design recommendations for successful application of the MPC7455. 9.1 PLL Configuration The MPC7455 PLL is configured by the PLL_CFG[0:4] 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 MPC7455 is shown in Table 17 for a set of 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 1-GHz column in Table 8. Note that these configurations were different in devices prior to Rev F; see Section 11.2, “Part Numbers Not Fully Addressed by This Document,” for more information regarding documentation of prior revisions.
