Note:
1. The tune bits adjust parameters that control PLL jitter. The recommended values minimize jitter for the PLL implemented in the
PPC405GP. These bits are shown for information only; and do not require modification except in special clocking circumstances
such as spread spectrum clocking. For details on the use of Spread Spectrum Clock Generators (SSCGs) with the PPC405GP,
visit the technical documents area of the IBM PowerPC web site.
2. Not all combinations of dividers produce valid operating configurations. Frequencies must be within the limits specified in “Clocking
Specifications” on page 47. Further requirements are detailed in the Clocking chapter of the
PowerPC 405GP Embedded
Processor User’s Manual.
3. Additional consideration must be given to pins that normally function as Trace signals. Improved design margin can be gained by
using three-state buffers instead of strapping resistors, and minimizing trace lengths and stubs.
