7.0 System Design Information
This section provides electrical and thermal design recommendations for successful application of the PowerPC 750CX.
7.1
PLL Configuration
The PowerPC 750CX 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 PowerPC
750CX is shown in the following table for nominal frequencies.
