The ICS9159-13 generates all clocks required for high speed RISC or CISC microprocessor systems such as 486, Pentium, PowerPC,Ô etc. Four different reference frequency multiplying factors are externally selectable with smooth frequency transitions. A test mode is provided to drive all clocks directly.
High drive BCLK outputs of the ICS9159-13 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 50±5% duty cycle.
