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.
Key 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) clocks. CPU and IOAPIC output buffer strength controlled b.
