Allowable Parameter Combinations
The MMCM module has the same restrictions on parameter combinations that are documented for the
MMCM_ADV primitive in the Virtex-6 User Guide and Virtex-6 Libraries Guide.
Note: The MMCM Module wrapper does not perform any error checking to enforce the design rules
and restrictions described in the Virtex-6 User Guide.
MMCM Module I/O Signals
The input and output signals of the MMCM module are described in Table 2.
