STEPLESS CLOCK FOR INTEL BROOKDALE CHIPSET  
IN  
Power good input signal comes from ACPI with high active. This  
3.3V input is level sensitive strobe used to determine FS [4:0] and  
MULTISEL0 input are valid and is ready to sample. This pin is high  
active.  
VTT_PWRGD  
26  
IN  
Power Down Function. This is internal 120K pull up. This is multi-  
function pin. When the VTT_PWRGD signal is asserted (this is,  
turns from a logical Low to high), the pin will be switched into the  
function of power down (PD#).  
PD#*  
3V66_0  
OUT  
OUT  
66MHz or 48MHz outputs selected by I2C register.  
VCH_CLK

INtd120k Latched input for FS4 at initial power up for H/W selecting the  
output frequency of CPU 3V66 and PCI clocks. This is internal 120K  
pull down.  
FS4&  
OUT 3.3V free running PCI clock during normal operation. This pin is with  
x1.5 ~ x2 driving strength.  
INtd120k Latched input for FS0 at initial power up for H/W selecting the  
output frequency of CPU, 3V66 and PCI clocks. This is internal  
120K pull down.  
PCICLK_F1^  
FS0&  
OUT 3.3V free running PCI clock outputs. This pin is with x1.5 ~ x2
