TH71101 General Description

PLL synthesizer (PLL SYNTH) for generation of the local oscillator signal LO
Parts of the PLL SYNTH are the high-frequency VCO1, the feedback divider DIV_16,a phase-frequency detector (PFD) with charge pump (CP) and a crystal-based reference oscillator(RO)
Low-noise amplifier (LNA) for high-sensitivity RF signal reception
First mixer (MIX1) for down-conversion of the RF signal to the IF
IF pre amplifier which is a mixer cell (MIX2) that operates as an amplifier IF amplifier (IFA) to amplify and limit the IF signal and for RSSI generation
Phase coincidence demodulator (DEMOD) with third mixer (MIX3) to demodulate the IF signal
Operational amplifier (OA) for data slicing, filtering and ASK detection
Bias circuitry for bandgap biasing and circuit shutdown
