... The W83196S-14 provides I2C serial bus interface to program the registers to enable or disable each clock outputs and choose the 0.5% center type spread spectrum to reduce EMI. The W83196S-14 accepts a 14.318 MHz reference crystal as its input and runs on a 3.3V supply. High drive PCI CLOCK outputs typically provide greater than 1V/nS slew rate into 30 pF loads. CPU CLOCK outputs typically provide better than 1V/nS slew rate into 20 pF loads as maintaining 50 5% duty cycle ...

... MODE = 1, these functions are not available. A particular clock could be enabled as both the 2- wire serial control interface and one of these pins indicate that it should be enabled. The W83196S-14 may be disabled in the low state according to the following table in order to reduce power consumption. All clocks are stopped in the low state, but maintain a valid high period on transitions from running to stop ...
