Note 3) IDD3 doesn’t include the current depending on Phase Detector Frequency. IDD3 is the current the Charge Pump
circuit consumes constantly.
Note 4) In the case of [PDN1]=”High” and [PDN2]=”High”, the total current consumption = IDD2 + IDD3.
Note 5) The shipment test is done with the exposed pad at the center of backside connected to VSS.
