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. For guaranteed specifications and test conditions see the Electrical Characteristics.
Note 2: This device is a high performance RF integrated circuit with an ESD rating <2 kV. Handling and assembly of this device should only be done at ESD
protected workstations.
Note 3: Phase Noise is measured using a reference evaluation board with a loop bandwidth of approximately 12 kHz. The phase noise specification is the
composite average of 3 measurements made at frequency offsets of 2.0, 2.5 and 3.0 kHz.
Note 4: See Charge Pump Measurement Definitions for detail on how these measurements are made.
Note 5: See Serial Input Data Timing.
Note 6: See FIN Sensitivity Test Setup.
Note 7: See OSCin Sensitivity Test Setup.
Note 8: Normalized Single-Side Band Phase Noise is defined as: LN(f) = L(f) − 20 log (FIN/Fφ), where L(f) is defined as the Single Side-Band Phase Noise.
Note 9: This parameter is derived from Normalized Single Side-Phase Noise, Ln(f).
Note 10: For FOSC frequencies below 10 MHz, it is recommended that the rise time of the signal does not exceed 25ns.
