FUNCTION
CPUCLK [ 0:3 ]
40,41,43,44
OUT
Low skew (< 250ps) clock outputs for host
frequencies such as CPU, Chipset and Cache.
Vddq2 is the supply voltage for these outputs.
IOAPIC
47
OUT
High drive buffered output of the crystal, and is
powered by VDDq2.
SDRAM [ 0:11]
17,18,20,21,28
,29,31,32,34,
35,37,38
O
SDRAM clock outputs which have the same
frequency as CPU clocks.
PCICLK_F/ *FS1
7
I/O
Latched input for FS1 at initial power up for H/W
selecting the output frequency of CPU, SDRAM and
PCI clocks.
Free running PCI clock during normal operation.
PCICLK 0 / *FS2
8
I/O
Latched input for FS2 at initial power up for H/W
selecting the output frequency of CPU, SDRAM and
PCI clocks.
PCI clock during normal operation.
PCICLK 1/ *FTS
10
I/O
Latched input for FTS at initial power up for H/W
selecting the output frequency of CPU, SDRAM and
PCI clocks.
PCI clock during normal operation.
