IF Input/Output Inverted. In RECEIVE Mode, functions with 1IF to present a

balanced first IF output port with 340W output impedance. Connection must

be AC coupled. It is recommended that the signal trace connected to this pin

be isolated from other signal or digital control lines to maintain receiver

sensitivity

In TRANSMIT Mode, functions with 1IF to present a balanced first IF input port

with 340W input impedance. Connection must be AC coupled. It is

recommended that the signal trace connected to this pin be isolated from other

signal or digital control lines to maintain receiver sensitivity

Receive RF Input signal. It is recommended that the nominal input impedance

of 20W on this pin be matched and be AC coupled

Received Signal Strength Indicator input

Digital to Analog Converter high output voltage defined by contents of Control

Register E

RSSI Threshold output. High output indicates RSSI input is greater than TPL.

Digital to Analog Converter output voltage

First Local Oscillator Tank circuit. T1LO and T1LOB provide a balanced pair

for connection to an external parallel inductor/capacitor tank circuit that

determines the frequency of oscillation

Inverted First Local Oscillator Tank circuit. T1LOTB and T1LO provide a

balanced pair for connection to an external parallel inductor/capacitor tank

circuit that determines the frequency of oscillation

Charge Pump output of 1LO Phase Locked Loop. Analog output switches

between VCC2 and ground

Charge Pump output of 2LO Phase Locked Loop charge pump output. Analog

output switches between VCC6 and ground as controlled by the phase detector

in the 2LO PLL

Second Local Oscillator Tank circuit. T2LO and GND (pin 44) provide an

unbalanced pair for a connection to an external parallel inductor/capacitor

tank circuit that determines the frequency of oscillation

Bandgap voltage output. Connection available for bypass capacitor

recommended for noise decoupling from Bandgap voltage reference.

Recommended capacitance value is 10nF connected to ground
