System Design Information
1.8 System Design Information
This section provides electrical and thermal design recommendations for successful application of the
XPC750P.
1.8.1 PLL Conguration
The XPC750Ps PLL is congured by the PLL_CFG[03] 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 XPC750P is shown in Table 14. for nominal frequencies.
