Description
The ICS9148-18 is a Clock Synthesizer chip for Pentium and PentiumPro CPU based Desktop/Notebook systems that will provide all necessary clock timing.
Features
- include two CPU and six PCI clocks. One reference output is available equal to the crystal frequency. Additionally, the device meets the Pentium power-up stabilization requirement, acheiving stable CPU and PCI clocks 2ms after power-up. PD# pin can enable a low power mode by stopping crystal OSC and PLL stages. Other power management features include, CPU_STOP# which stops CPU (0:1) clocks, and PCI_STOP# which stops PCICLK (0:4) clocks. High drive CPUCLK outputs typically provide greater than 1.
