generation of pulses on the motherboard

--- Look I got a response in another SITE: <BR> "that crystal generates a frequency of 14 MHz (can not remember the value <BR> correct) for the PLL (Phase Lock Loop) and this fa multiplication <BR> to get other frequencies, the FSB is the frequency that works the chipset, memory and <BR> inputs and outputs of the processor. basically <BR> PLL generates two frequencies: 33 MHz (PCI) and 100 MHz (FSB), to obtain the frequency of the ISA bus <BR> he divides the frequency of the PCI by 5 or 4, to obtain the frequency of the AGP <BR> he does PCI X 2, (hence the term AGP 2X, 4X ), to make <BR> BUS 133MHz FSB PCI he adds, that everything within that CI-side <BR> crystal! <BR> Montoia "<BR> is anyway, is that correct --- It's more or less, because today chipsets are capable of managing transfers at different frequencies for front side bus (communication with the processor) and memory (FSB at 100 and memory 133, for example). <BR> Really great part of the work is not done only by the clock generator (although it is very important), but also by the chipset. --- Eh so right!
