Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. These ratings are stress specifications only and functional operation of the device at these or any other conditions above those listed in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect product reliability.

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.

High drive BCLK outputs of the ICS9159-12 provide greater than 1V/ns slew rate into 30pF loads. PCLK outputs provide better than 1V/ ns slew rate into 20pF loads while maintaining ±5% duty cycle.
