AV9159C-02CW28 Datasheet PDF - Integrated Circuit Systems

General Description
The ICS9159C-02 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. A test mode is provided to drive all clocks directly.

FEATUREs
• Generates up to four processor and six bus clocks, plus disk, keyboard and reference clocks
• Synchronous clocks skew matched to 250ps window on PCLKs and 500ps window on BCLKs
• Test clock mode eases system design
• Custom configurations available:
    Output frequency ranges to 100 MHz on options
    Selectable multiplying and processor/bus ratios
    Stop clock control stops clock glitch-free; available as mask option
• 3.0V - 5.5V supply range
• 28-pin SOIC package

APPLICATIONs
• Ideal for high-speed RISC or CISC systems such as 486, Pentium, PowerPC, etc.
