Electrical Characteristics
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 Char-
acteristics.
Note 2: This device is a high performance RF integrated circuit and is ESD sensitive. Handling and assembly of this device should be done on ESD protected work-
stations.
Note 3: PLL V
Note 4: Guaranteed by design. Not tested in production.
