The W83L197R-16 is a Clock Synthesizer which provides all clocks required for high-speed RISC or CISC microprocessor. Four different frequency of CPU, and PCI clocks are externally selectable with smooth transitions. The 0.5% or 0.75% center type spread spectrum can be selected to reduce EMI. The W83L197R-16 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 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 5% duty cycle. The fixed frequency outputs as REF, 48 MHz provide better than 0.5V /ns slew rate. |
