FUNCTION
External Bias Resistor. Connect a 100k Ω ± 1% resistor in parallel with a 0.1μF capacitor in
series with a 71k Ω resistor to GND.
External Bias Capacitor. Connect a 0.1μF capacitor to GND.
Supply Voltage. Bypass to GND with 100pF and 100nF capacitors as close to the pin as
possible with the smaller value capacitor closer to the pin.
Ground. Connect to PC board ground plane.
LNA Input. Requires external matching network.
IF Output Select. Selects output type. Drive high for single-ended output, drive low for
differential output.
Internally Connected. Leave unconnected.
Digital Control Clock
Clock Output Enable 2. Drive high to enable limited-swing clock output.
Clock Output Enable 1. Drive high to enable full-swing clock output.
AGC External Filter

Limited-Swing Clock Output
Digital-Control Data Input
Shutdown. Drive SHDN low to disable all device functions. Drive SHDN high for normal
operation.
VCO Tuning Input. Connect directly to the loop filter output.
Charge-Pump Output. Connect directly to the loop filter input.
Crystal Oscillator Input. Connect XTALIN1 and XTALIN2 together and to the TCXO output
through a coupling capacitor.
Exposed Paddle. Internally connected to GND. Connect to PC board ground plane for
optimal performance.
