ICS9148-75 Overview
The ICS9148-75 generates all clocks required for high speed RISC or CISC microprocessor systems such as Intel PentiumPro™, AMD™ or Cyrix™. Sixteen different reference frequency multiplying factors are externally selectable with smooth frequency transitions. Spread spectrum may be enabled through I2C programming.
