Absolute Maximum Ratings
Stresses greater than those listed in this table may cause per-
manent damage to the device. These represent a stress rating
only. Operation of the device at these or any other conditions
above those specified in the operating sections of this specifi-
cation is not implied. Maximum conditions for extended peri-
ods may affect reliability.

Notes:
1.
All clock outputs loaded with 6" 60
transmission lines with 20-pF capacitors.
2.
CPU_STOP#, PCI_STOP#, PWR_DWN#, SPREAD#, and SEL48# logic inputs have internal pull-up resistors (not CMOS level).
3.
X1 input threshold voltage (typical) is V
/2.
4.
The W137 contains an internal crystal load capacitor between pin X1 and ground and another between pin X2 and ground. Total load placed on crystal is
14 pF; this includes typical stray capacitance of short PCB traces to crystal.
5.
X1 input capacitance is applicable when driving X1 with an external clock source (X2 is left unconnected).
