MPC8349E Clock Connection

Dear MPC8349E expert,

I'm going to use MPC8349E processor for main processing unit on the new project.

I'm confused about the clock connection.

To provide information about our system, processor e300 core frequency grade is AL(667MHz), platform frequency is 333MHz, and CSB frequency will be 333MHz, as well local bus frequency will be 133MHz, and we will not use PCI port.

In this case, according to MPC8349EEC or MPC8349EARM, connecting the clock to 66MHz or 66.67MHz is mixed. I wonder if I should connect to the 66MHz or 66.67MHz option.

I look forward to your kind response.

You can apply up to 66.67MHz - minimal CLKIN/PCI_CLK cycle time is 15 ns.
