Clock Input Timing

This section provides the clock input DC and AC electrical characteristics for the chip. Note that the

PCI_CLK/PCI_SYNC_IN signal or CLKIN signal is used as the PCI input clock depending on whether

the device is configured as a host or agent device. CLKIN is used when the device is in host mode.
