The W83194R-KX is a clock generator which provides all clocks required for AMD K7 system. W83194R-KX provides one differential pair CPU clock open drain outputs up to 143MHz which are externally selectable with smooth transitions. W83194R-KX also provides 6 PCI clocks and 13 SDRAM clocks controlled by the none-delay buffer_in pin. The W83194R-KX accepts a 14.318 MHz reference crystal as its input and runs on a 3.3V supply. Spread spectrum built in at 0.5% or 0.25% to reduce EMI. Programmable stopping individual clock 2
