... General Description The ICS9248-165 is a single chip clock solution for Desktop designs. It provides all necessary clock signals for such a system. Spread spectrum may be enabled through I Spread spectrum typically reduces system EMI by 8dB to 10dB. This simplifies EMI qualification without resorting to board design iterations or costly shielding. The ICS9248-165 ...

... CLK_STOP asychronous input to the clock synthesizer used to turn off the CPU, IOAPIC, SDRAM clocks for low power operation. CLK_STOP# is synchronized by the ICS9248-165. The minimum that the CPU clock is enabled (CLK_STOP# high pulse) is 100 CPU clocks. All other clocks will continue to run while the CPU, IOAPIC, SDRAM clocks are disabled. The CPU clocks will always be stopped in a low state and start in such a manner that guarantees the high pulse width is a full pulse ...
