Power Dissipation (Static and Dynamic) (Note 2)
1400 mW
Note 1:
The Absolute Maximum Ratings are those values beyond which the
safety of the device cannot be guaranteed. The device should not
be operated at these limits. The parametric values defined in the
DC and AC Electrical Characteristics tables are not guaranteed at
the Absolute Maximum Ratings. The Recommended Operating
Conditions will define the conditions for actual device operation.
Note 2:
Power dissipation is calculated using 49
§
/W as the thermal coeffi-
cient for the PCC package at 225 LFM airflow. The input frequency
is assumed at 33 MHz with CLK4 at 132 MHz and CLK2 and
CLK1’s being at 66 MHz. In addition the ambient temperature is
assumed 70

with power supply at 5.0V.
