... 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 outputs and frequency selection through I stabilization, which requires CPU and PCI clocks be stable within 2 ms after power-up ...

... When MODE=0, pins 2 is inputs (CPU_STOP#), when MODE=1, these functions are not available. The W83194R-KXmay be disabled in the low state according to the PD# pin41 in order to reduce power consumption. All clocks are stopped in the Power Down state when PD# is set to LOW, but maintain a valid high period on transitions from running to stop. ...
