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. |
