Description
The ICS9148-12 is a Clock Synthesizer chip for Pentium and PentiumPro CPU based Desktop/Notebook systems that will provide all necessary clock timing.
Features
- include four strong CPU, seven PCI and eight SDRAM clocks. Two reference outputs are available equal to the crystal frequency. Stronger drive CPUCLK outputs typically provide greater than 1 V/ns slew rate into 20pF loads. This device meets rise and fall requirements with 2 loads per CPU output (ie, one clock to CPU and NB chipset, one clock to two L2 cache inputs). PWR_DWN# pin allows low power mode by stopping crystal OSC and PLL stages. For optional power management, CPU_STOP# can stop CPU (0:.
