PPC740 and PPC750 Hardware Specifications
31 of 43
This section provides electrical and thermal design recommendations for successful
application of the PPC740 and PPC 750.
7.1 PLL Conguration
The PLL for the PPC740 and PPC750 is congured by the PLL_CFG[0-3-] signals. For a
given SYSCLK (bus) frequency, the PLL conguration signals set the internal CPU and
VCO frequency of operation. The PLL conguration for the PPC740 and PPC750 is
shown in Table 16 for nominal frequencies.
Notes:
1. Reserved settings.
2. SYSCLK min is limited by the lowest frequency that manufacturing will support, see Section 3.1.2.1,
