... W83194R-630A provides the 0.5%, 0.75% center type and 0~0.5% down type spread spectrum to reduce EMI. The W83194R-630A accepts a 14.318 MHz reference crystal as its input and runs on a 3.3V supply. High drive PCI and SDRAM CLOCK outputs typically provide greater than 1 V /ns slew rate into 30 pF loads. CPU CLOCK outputs typically provide better than 1 V /ns slew rate into 20 pF loads as maintaining 50± ...

... All proceeding bytes must be sent to change one of the control bytes. The 2-wire control interface allows each clock output individually enabled or disabled. W83194R-630A initializes with default register settings, and then it ptional to use the 2-wire control interface. The SDATA signal only changes when the SDCLK signal is low, and is stable when SDCLK is high during normal data transfer ...
