General Description
The ICS9159C-14 generates all clocks required for high speed RISC or CISC microprocessor systems such as 486, Pentium, PowerPC, etc. Four different reference frequency multiply-ing factors are externally selectable with smooth frequency transitions. These multiplying factors can be customized for specific applications. It has a TURBO pin that can speed up the 60 and 66.6 MHz clocks by 2.5%.

FEATUREs
• 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
• TURBO input pin that can speed up the 60 and 66.6 MHz PCLKs by 2.5%.
• 2.5V or 3.3V output: PCLK (0:3)
• 3.0V - 5.5V supply range
• 28-pin SOIC package
