PCI33_HT66 MHz Select:
This input selects the
output frequency of PCI33_
HT
66 outputs to either 33
MHz or 66 MHz. This input pin is dedicated to avoid
corruption of the input state due to PCI add-in cards
that may have termination resistors on the input
clocks. This input must have a weak (100K) internal
pullup resistor. This pin externally strapped low using
a 10 K ohm resistor to select if the 66 Mhz outputs are
desired.
Low = 66 MHz outputs, High = 33 MHz
outputs
3.3-V USB Clock Output:
Fixed clock output at 48-
MHz.
3.3-V Super I/O clock output:
The Super I/O clock
may be strapped for 24-MHz or 48-MHz. This input
must have a weak (100K) internal pullup. This pin
will be externally strapped low using a 10 K ohm if
the 48 MHz output is desired.
Low = 48 MHz output,
high = 24 MHz output
3.3V Reference Clock Outputs:
Fixed clock output
at 14.318 MHz .
Frequency Select Inputs:
Power-On strapping to set
device operating frequency as described in Table 2 on
page 11. These inputs must have weak (100 K)
internal pullup resistors. See Notes in Table 2 on page
11 for resistor strapping recommendation.
Spread Spectrum Clocking Enable:
Power-On
strapping that sets spread spectrum clocking as
enabled or disabled. This input allows the default
spread spectrum-clocking mode to be enabled or
disabled upon power up. This input must have a weak
(100K) internal pullup resistor. This pin is externally
strapped low using a 10 K ohm resistor if spread
disabled is desired.
Low=disable, High=enable.
Note:
all AMD Athlon processors and
AMD64 processor-based systems are
recommended for use with SSC, therefore the
default of this pin is enabled and should only be
turned off for debug and test purposes.
