Recommended Operating Conditions
Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. "Recommended Operating Conditions" indicate conditions for
which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical
Characteristics. The guaranteed specifications apply only for the test conditions listed. The voltage at all the power supply pins of VddRF1, VddRF2, VddRF3,
VddRF4, VddRF5, VddIF1 and VddIF2 must be the same. V
