Clock Synthesizer
- Place all decoupling caps as clos e to VCC/GND pins as possible
Notes:
Minimize Stub Length from
CLK14 trace to
JP20A.
- PCI_0/ICH pin has to go to the ICH.
- CPU_ITP pin must go to the ITP. It is the only
CPU CLK that can be shut off through the SMBUS interface.
(This clock cannot be turned off through SMBus)
