Spread Spectrum Control, JP1
When LPCI-8575 plugged into the expansion chassis, it pro-
vides a discrete clock signal to each of the peripheral slot
defined as a PCI clock (CLK0, CLK1, CLK2 and CLK3).
An important feature of the LPCI-8575 expansion modules is
that it support 33MHz/66MHz clock operating environment. As
system clock increase, electromagnetic interference (EMI)
becomes a challenge for the system designers. LPCI-8575
