Notes:
The allowable ambient temperature range specied is based on the module mounted to a
50 X 50 mm 2-signal/2-power plane card with natural convection (no air ow).
SI can also be operated at 60 MHz with an increase in power of less than 5%. This does not
change the application conditions shown in this table.
