General Description
The ICS9159-12 generates all clocks required for mobile microprocessor systems based on Pentium/Mobile Triton chip sets. Three different reference frequency multiplying factors are externally selectable with smooth frequency transitions. These multiplying factors can be customized for specific plications. A test mode is provided to drive all clocks directly.
