APPROVED PRODUCT
C9811x2
Clock Synchronization and Phase Alignment
This device incorporates IOAPIC clock synchronization. With this feature, the IOAPIC clocks are derived from the CPU
clock. The IOAPIC clock lags the CPU clock by the specified 1.5 to 3.5 nSec. Figure 3 shows the relationship between
the CPU and IOAPIC clocks.
