1.8 System Design Information
This section provides electrical and thermal design recommendations for successful application
of the 604e.
1.8.1 PLL Configuration
The 604e 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 604e is shown in Table 11 for nominal frequencies.
