Byte 5, bit 6: 0 = CR#_A controls SRC0 (default), 1= CR#_A# controls SRC2.
PWR Power supply for PCI clocks, nominal 3.3V
3.3V PCI clock output / SRC5 enable strap. On powerup, the logic value on this pin determines if SRC5 or
CPU_STOP#/PCI_STOP# is enabled. The latched value controls the pin function as follows
I/O

JItter specs are specified as measured on a clock characterization board. System designers need to take special care not to use these numbers, as the in-system

Phase jitter requirement: The deisgnated Ge2 outputs will meet the reference clock jitter requiremernts from the PCI Express Gen2 Base Spec. The test is performed on a

methodology is as defined by the PCI SIG.
