LNA Ground connection
RF Input to the First Down-Converter
IF Output from the First Down-Converter
First Down-Converter Ground connection
RF Input to the Second Down-Converter
IF Output from the Second Down-Converter
Second Down-Converter, Limiting Amplifier, RSSI, and
Demodulator stages - Ground connection
Input to the Limiting Amplifier
External Decoupling capacitors – one required at each limiting
Amplifier Inputs
Receive Signal Strength Indicator output
Quadrature input to the FM Demodulator
Output from the Limiting Amplifier
Power supply to the Second Down-Converter, Limiting Amplifier,
RSSI and Demodulator stages – nominally 3.0V
Output of the FM/FSK Quadrature Demodulator
Emitter connection to the Second Down-Converter Local Oscillator
transistor
Base connection to the Second Down-Converter Local Oscillator
transistor
Buffered Local Oscillator (Open-Collector) output from the First
Down-Converter
First Down-Converter 3V Supply
First Down-Converter Local Oscillator (VCO) TANK/Resonator
connection
First Down-Converter VCO Ground connection
LNA Power Supply – nominally 3.0V
External LNA bias decoupling capacitor
LNA Gain control logic input. A logic ‘0’ provides a typical power
gain of 16dB and a logic ‘1’ provides an attenuation of 6dB
Zero-Power logic control. A logic ‘0’ powers down the device.
