GENERAL DESCRIPTION
ADF4216: 550 MHz/1.2 GHz
The ADF4216/ADF4217/ADF4218 are dual frequency synthe-
ADF4217: 550 MHz/2.0 GHz sizers that can be used to implement local oscillators (LOs) in
ADF4218: 550 MHz/2.5 GHz the upconversion and downconversion sections of wireless
2.7 V to 5.5 V Power Supply receivers and transmitters. They can provide the LO for both
Selectable Charge Pump Currents the RF and IF sections. They consist of a low-noise digital PFD
