FUNCTION

Low skew (< 250ps) clock outputs for host

frequencies such as CPU and Chipset.

Pin16 *Mode1=1, Power Down mode when driven

low.

Pin16 *Mode1=0, RESET# output (4ms low active

pulse when Watch Dog time out)

Clock outputs synchronous with PCI clock and

powered by VddA.

SDRAM clock outputs.

3.3V 33MHz PCI clock during normal operation.

Latched input for FS0 at initial power up for H/W

selecting the output frequency of CPU, SDRAM and

PCI clocks(Default=1).

Low skew (< 250ps) PCI clock outputs.

Latched input for FS1 at initial power up for H/W

selecting the output frequency of CPU, SDRAM and

PCI clocks(Default=0).

Low skew (< 250ps) PCI clock outputs.

Latched input for FS2 at initial power up for H/W

selecting the output frequency of CPU, SDRAM and

PCI clocks(Default=1).

PCI clock during normal operation.

Latched Input. *Mode1=1, Pin 29 is PD#; *Mode1=0,

Pin 29 is RESET$

Low skew (< 250ps) PCI clock outputs.

3.3V output clocks for the chipset.
