Figure 41 shows the internal distribution of the clocks.
Figure 41. MPC8349EA Clock Subsystem
The primary clock source can be one of two inputs, CLKIN or PCI_CLK, depending on whether the device
is configured in PCI host or PCI agent mode. When the MPC8349EA is configured as a PCI host device,
CLKIN is its primary input clock. CLKIN feeds the PCI clock divider (
÷2) and the multiplexors for
PCI_SYNC_OUT and PCI_CLK_OUT. The CFG_CLKIN_DIV configuration input selects whether
CLKIN or CLKIN/2 is driven out on the PCI_SYNC_OUT signal. The OCCR[PCICDn] parameters select
whether CLKIN or CLKIN/2 is driven out on the PCI_CLK_OUTn signals.
PCI_SYNC_OUT is connected externally to PCI_SYNC_IN to allow the internal clock subsystem to
synchronize to the system PCI clocks. PCI_SYNC_OUT must be connected properly to PCI_SYNC_IN,
with equal delay to all PCI agent devices in the system, to allow the MPC8349EA to function. When the
device is configured as a PCI agent device, PCI_CLK is the primary input clock and the CLKIN signal
should be tied to GND.
