Pentium/ProTM System Clock Chip
General Description
The ICS9148-02 is a Clock Synthesizer chip for Pentium and PentiumPro CPU based Desktop/Notebook systems that will provide all necessary clock timing.
Features include four CPU, seven PCI and eight SDRAM clocks.
Two reference outputs are available equal to the crystal frequency.
Additionally, the device meets the Pentium power-up stabilization, which requires that CPU and PCI clocks be stable within 2ms after power-up.
PWR_DWN# pin allows low power mode by stopping crystal OSC and PLL stages.
For optional power management, CPU_STOP# can stop CPU (0:3) clocks and PCI_STOP# will stop PCICLK (0:5) ...
