The 9159-14 generates all clocks required for high speed RISC or CISC microprocessor systems such as 486, Pentium, PowerPC, etc. Four different reference frequency multiplying factors are externally selectable with smooth frequency transitions. These multiplying factors can be customized for specific applications. High drive BCLK outputs provide typically greater than 1V/ ns slew rate into 30pF loads. PCLK outputs provide typically better than 1V/ns slew rate into 20pF loads while maintaining ±5% duty cycle.


  • Generates up to four processor and six bus clocks, plus disk, USB and reference clocks
  • Synchronous clocks skew matched to 250ps window on PCLKs and 500ps window on BCLKs
  • 3.0V - 5.5V supply range
  • 28-pin SOIC package
