Pentium/ProTM System Clock Chip

The ICS9148-32 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 and eight PCI Clocks Three reference outputs are available equal to the crystal frequency. Additionally, the device meets the Pentium power-up stabilization requirement, assuring that CPU and PCI Clocks are stable within 2ms after power-up. PD# pin enables low power mode by stopping crystal OSC and PLL stages. Other Power Management features include CPU_STOP#, which stops CPU (0:3) Clocks and PCI_STOP#, which stops PCICLK (0:6) Clocks Serial I2C Interface allows Power Management by output Clock disabling. High drive CPUCLK outputs typically provide greater than 1 V/ns slew rate into 20pF loads. PCICLK outputs typically provide better than 1V/ns slew rate into 30pF loads while maintaining 505% duty cycle. The REF Clock outputs typically provide better than 0.5V/ns slew rates. The ICS9148-32 accepts a 14.318MHz reference crystal or Clock as its input and runs on a 3.3V core supply. By Integrated Device Technology
