FUNCTION
LNA Supply Voltage
LNA Ground
Receiver and Transmitter Gain-Control Logic-Input Bit 6
Antenna 1. Differential Input to LNA in Rx mode. Input is internally AC-coupled and matched to 100 ?
differential. Connect directly to a 2:1 balun.
Receiver Gain-Control Logic-Input Bit 7
Supply Voltage for Second Stage of Power Amplifier
Receiver and Transmitter Gain-Control Logic-Input Bit 3
Antenna 2. Differential inputs to LNA in diversity Rx mode and to PA differential outputs in Tx mode.
Internally AC-coupled differential outputs and matched to 100 ? differential. Connect directly to a 2:1 balun.
Receiver and Transmitter Gain-Control Logic-Input Bit 2
Active-Low Shutdown and Standby Logic Input. See Table 32 for operating modes.
Supply Voltage for First-Stage of PA and PA Driver
Receiver and Transmitter Gain-Control Logic-Input Bit 5
Active-Low Chip-Select Logic Input of 3-Wire Serial Interface (see Figure 3)
RSSI, PA Power Detector or Temperature-Sensor Multiplexed Analog Output
Transmitter Upconverter Supply Voltage
Serial-Clock Logic Input of 3-Wire Serial Interface (see Figure 3)
Data Logic Input of 3-Wire Serial Interface (see Figure 3)
PLL and Registers Supply Voltage. Connect to the supply voltage to retain the register settings.
Reference Clock Buffer Output
Lock-Detect Logic Output of Frequency Synthesizer. Output high indicates that the frequency synthesizer is
locked. Output programmable as CMOS or open-drain output. (See Tables 17 and 21.)
Receiver and Transmitter Gain-Control Logic-Input Bit 1
Charge-Pump Output. Connect the frequency synthesizer’s loop filter between CPOUT and TUNE (see the
Block Diagram/Typical Operating Circuit ).
PLL Charge-Pump Supply Voltage
Charge-Pump Circuit Ground
Crystal Oscillator Supply Voltage
Crystal or Reference Clock Input. AC-couple a crystal or a reference clock to this analog input.
Connection for Crystal Oscillator Off-Chip Capacitors. When using an external reference clock input, leave
CTUNE unconnected.
VCO Supply Voltage
VCO Ground
VCO TUNE Input (see the Block Diagram/Typical Operating Circuit )
On-Chip VCO Regulator Output Bypass. Bypass with a 0.1μF to 1μF capacitor to GND. Do not connect
other circuitry to this point.
Receiver and Transmitter Gain-Control Logic-Input Bit 4
