FUNCTION
Data Digital Input of 3-Wire Serial Interface (See Figure 2)
Clock Digital Input of 3-Wire Serial Interface (See Figure 2)
Active-Low Enable Digital Input of 3-Wire Serial Interface (See Figure 2)
Lock-Detect Digital Output of Frequency Synthesizer. Output high indicates that the
frequency synthesizer is locked.
Reference Oscillator Input. Connect an external reference oscillator to this analog input.
PLL Charge-Pump Supply Voltage. Bypass with a capacitor as close to the pin as
possible. Do not share the bypass-capacitor ground vias with any other branches.
Charge-Pump Circuit Ground. Make connections to ground vias as short as possible. Do
not share ground vias with any other branches.
Charge-Pump Output. Connect the frequency synthesizer ’ s loop filter between CPOUT

and TUNE. Keep the line from this pin to the tune input as short as possible to prevent
spurious pickup. Connect C2 as close to CPOUT as possible. Do not share the capacitor
ground vias with any other branches (see the Typical Operating Circuit ).

VCO Ground. Make connections to ground vias as short as possible. Do not share ground
vias with any other branches.
VCO TUNE Input. Connect C1 as close to TUNE as possible. Connect the ground of C1 to

Active-Low Shutdown Digital Input. Set high to enable the device.
RSSI or Temperature-Sensor Multiplexed Output
Rx Mode Enable Digital Input. Set high to enable Rx.
Rx Baseband AC-Coupling Highpass Corner Frequency Control Digital Input Selection Bit
Rx Baseband Q-Channel Differential Outputs. In Tx calibration mode, these pins are the
LO leakage and sideband-detector outputs.
Rx Baseband I-Channel Differential Outputs. In Tx calibration mode, these pins are the LO
leakage and sideband-detector outputs.
Rx Baseband Buffer Supply Voltage. Bypass with a capacitor as close to the pin as
possible. Do not share the bypass-capacitor ground vias with any other branches.
Rx/Tx Gain-Control Digital Input Bit 1
Rx Baseband Filter Supply Voltage. Bypass with a capacitor as close to the pin as
possible. Do not share the bypass-capacitor ground vias with any other branches.
