REFIN pin is input one third of the 2nd LO input frequency.
Charge pump 1 current is determined by the setting in {CP1[2:0]} which is described on page 22.
Charge pump 2 current is determined by the setting in {CP2[2:0]} which is described on page 23.

[PDN]=”High”, {PDSYNTH_N}=”High” , the total current consumption = IDD_SYN2+IDD_SYN3
In the shipment test, the exposed pad on the center of the back of the package is connected to
ground.
When 2nd LO input frequency is used 28.8MHz, set {PDTRI_N}=0 and input the 2nd LO
signal(28.8MHz) from LO2NDIN pin. Then REFIN Frequency is set 28.8MHz/3=9.6MHz.
