3.2 Platform Clocking
The Intel
®
EP80579 Development Board uses one CK-410 clock synthesizer to generate
the host differential pair clocks and the 100 MHz differential clock to the DB800. The
DB800 then generates the 100 MHz differential pair clock for PCI Express devices.
Figure 5 shows the board clocking configuration.
