DDR/DDRCLK PLL Ratio
The dual DDR memory controller complexes can be synchronous with, or asynchronous to, the CCB,
depending on configuration.
Table 79 describes the clock ratio between the DDR memory controller complexes and the DDR PLL
reference clock, DDRCLK, which is not the memory bus clock. The DDR memory controller complexes
clock frequency is equal to the DDR data rate.
When synchronous mode is selected, the memory buses are clocked at half the CCB clock rate. The default
mode of operation is for the DDR data rate for both DDR controllers to be equal to the CCB clock rate in
synchronous mode, or the resulting DDR PLL rate in asynchronous mode.
In asynchronous mode, the DDR PLL rate to DDRCLK ratios listed in Table 79 reflects the DDR data rate
to DDRCLK ratio, since the DDR PLL rate in asynchronous mode means the DDR data rate resulting from
DDR PLL output.
Please note that the DDR PLL reference clock input, DDRCLK, is only required in asynchronous mode.
MPC8572E does not support running one DDR controller in synchronous mode and the other in
asynchronous mode.
