The W83195R-08 is a Clock Synthesizer which provides all clocks required for high-speed RISC or CISC microprocessor such as Intel Pentium II. W83195R-08 provides sixteen CPU/PCI frequencies which are externally selectable with smooth transitions. W83195R-08 also provides 17 SDRAM clocks controlled by the none-delay buffer_in pin.
The W83195R-08 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 I2C interface. The device meets the Pentium power-up stabilization, which requires CPU and PCI clocks be stable within 2 ms after power-up. Using dual function pin for the slots(ISA, PCI, CPU, DIMM) is not recommend. The
add on cards may have a pull up or pull down.
High drive seven PCI and SDRAM CLOCK outputs typically provide greater than 1 V /ns slew rate into 30 pF loads. Two CPU CLOCK outputs typically provide better than 1 V /ns slew rate into 20 pF loads, when maintaining 50·· 5% duty cycle. The fixed frequency outputs, such as REF, 24MHz and 48 MHz provide better than 0.5V /ns slew rate.

The W83196S-14 is a Clock Synthesizer which provides all clocks required for high-speed RISC or CISC microprocessor. Twelve different frequency of CPU, and PCI clocks are externally selectable with smooth transitions.
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. The fixed frequency outputs as REF, 24 MHz, and 48 MHz provide better than 0.5V/nS slew rate.
