ICS9148-53 Overview
The ICS9148-53 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.
