Overview

Integrated Circuit Systems, Inc.
ICS9148-18 Pentium/ProTM System Clock Chip General 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.
