... The W83194AR-We provides I each clock outputs and provides 0.5% and 0.75% center type spread spectrum to reduce EMI. The W83194AR-We 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± ...
