FUNCTION
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 TUNEVCO. Connect to the PCB ground plane.
Ground for Synthesizer. Connect to the PCB ground plane.
Charge-Pump Output. Connect this output to the PLL loop filter input with the shortest
connection possible.
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.
