23 Clocking
This figure shows the internal distribution of clocks within this chip.
Figure 64. Clock Subsystem
The primary clock source for the device 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 device 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[PCICOEn]
parameters select whether CFG_CLKIN_DIV 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 device to function. When the device
is configured as a PCI agent device, PCI_CLK is the primary input clock. When the device is configured
as a PCI agent device the CLKIN signal should be tied to GND.
