FUNCTION
DC Power Supply for LNA. Connect to a +3.3V low-noise supply. Bypass to GND with a 1nF capacitor
connected as close as possible to the pin. Do not share capacitor ground vias with other ground connections.
DC Power Supply for LNA. Connect to a +3.3V low-noise supply. Bypass to GND with a 1nF capacitor
connected as close as possible to the pin. Do not share capacitor ground vias with other ground connections.
Ground. Connect to board’s ground plane for proper operation.
Wideband 75 ? RF Input. Connect to an RF source through a DC-blocking capacitor.
RF Gain-Control Input. High-impedance analog input with a 0.5V to 2.7V operating range.
V GC1 = 0.5V corresponds to the maximum gain setting.
DC Power Supply for LO Generation Circuits. Connect to a +3.3V low-noise supply. Bypass to GND with
a 1nF capacitor connected as close as possible to the pin. Do not share capacitor ground vias with
other ground connections.
DC Power Supply for VCO Circuits. Connect to a +3.3V low-noise supply. Bypass to GND with a 1nF
capacitor connected as close as possible to the pin. Do not share capacitor ground vias with other
ground connections.
Internal VCO Bias Bypass. Bypass to GND with a 100nF capacitor connected as close as possible to
the pin. Do not share capacitor ground vias with other ground connections.
High-Impedance VCO Tune Input. Connect the PLL loop filter output directly to this pin with as short of a
connection as possible.
Ground for VTUNE. Connect to the PCB ground plane.
Ground for Synthesizer. Connect to the PCB ground plane.

DC Power Supply for Synthesizer Circuits. Connect to a +3.3V low-noise supply. Bypass to GND with a
1nF capacitor connected as close as possible to the pin. Do not share capacitor ground vias with other
ground connections.
Crystal-Oscillator Interface. Use with an external parallel-resonance-mode crystal through a series 1nF
capacitor. See the Typical Application Circuit .
Crystal-Oscillator Buffer Output. A DC-blocking capacitor must be used when driving external circuitry.
DC Power Supply for Digital Logic Circuits. Connect to a +3.3V low-noise supply. Bypass to GND with a
1nF capacitor connected as close as possible to the pin. Do not share capacitor ground vias with other
ground connections.
Quadrature Baseband Differential Output. AC-couple with 47nF capacitors to the demodulator input.
In-Phase Baseband Differential Output. AC-couple with 47nF capacitors to the demodulator input.
I-Channel Baseband DC Offset Correction. Connect a 47nF ceramic chip capacitor from IDC- to IDC+.
Q-Channel Baseband DC Offset Correction. Connect a 47nF ceramic chip capacitor from QDC- to QDC+.
DC Power Supply for Baseband Circuits. Connect to a +3.3V low-noise supply. Bypass to GND with
a 1nF capacitor connected as close as possible to the pin. Do not share capacitor ground vias with
other ground connections.
