Pins
Description
REF
56
3.3V 14.318-MHz clock output.
XTAL_IN
2
14.318-MHz crystal input.
XTAL_OUT
3
14.318-MHz crystal input.
CPU, CPU# [0:2]
44, 45, 48, 49, 51, 52
Differential CPU clock outputs.
3V66_0
33
3.3V 66-MHz clock output.
3V66_1/VCH
35
3.3V selectable through SMBus to be 66 MHz or 48 MHz.
66IN/3V66_5
24
66-MHz input to buffered 66BUFF and PCI or 66-MHz clock from
internal VCO.
66BUFF [2:0] /3V66 [4:2]
21, 22, 23
66-MHz buffered outputs from 66Input or 66-MHz clocks from internal
VCO.
PCI_F [0:2]
5, 6, 7,
33-MHz clocks divided down from 66Input or divided down from 3V66.
PCI [0:6]
10, 11, 12, 13, 16, 17, 18
PCI clock outputs divided down from 66Input or divided down from
3V66.
USB
39
Fixed 48-MHz clock output.
DOT
38
Fixed 48-MHz clock output.
S2
40
Special 3.3V 3-level input for Mode selection.
S1, S0
54, 55
3.3V LVTTL inputs for CPU frequency selection.
IREF
42
A precision resistor is attached to this pin, which is connected to the
internal current reference.
MULT0
43
3.3V LVTTL input for selecting the current multiplier for the CPU
outputs.
PWR_DWN#
25
3.3V LVTTL input for Power_Down# (active LOW).
PCI_STOP#
34
3.3V LVTTL input for PCI_STOP# (active LOW).
CPU_STOP#
53
3.3V LVTTL input for CPU_STOP# (active LOW).
PWRGD#
28
3.3V LVTTL input is a level sensitive strobe used to determine when
S[2:0] and MULTI0 inputs are valid and OK to be sampled (Active
LOW). Once PWRGD# is sampled LOW, the status of this output will
be ignored.
