9. m Clock LANES 3 0 Spread Spectrum Clock 1 0V Spread Spectrum Clocking Spread Spectrum Clocking is a method of varying the clock frequency to reduce EMI by spreading noise emissions across a broad spectrum of frequencies The required PCI Express method is to modulate the clock frequency in a manner that does not allow the clock frequency to go higher than the nominal frequency In a SuperSwitch system processors are connected using a non transparent bridge In a non transparent bridge both sides of the bridge Host and Target have the potential to use individual Spread Spectrum Clocks However the modulated clocks on either side of the bridge are not in sync with each other and could cause data to be lost To allow the use of Spread Spectrum Clocking on both sides of the bridge the Target Cable Adapter uses two 8508 switch chips These chips support Dual Clocking Mode which allows the chip to transmit and receive two PCle clocks simultaneously A constant frequency clock is established between the two switch chips using one of the PCI Clock lines on each of the chips and the other clock line on each chip accepts a Spread Spectrum Clock from either the Host or Target This setup allows both systems to use Spread Spectrum Clocking One Stop Systems Inc Target Cable Adapter User Manual Rev A 5 Switches The Target Cable Adapter contains one x4 d
