General Description

The TH7122 is a single chip FSK/FM/ASK transceiver IC. It is designed to operate in low-power multi-

channel programmable or single-channel stand-alone, half-duplex data transmission systems. It can be used

for applications in automotive, industrial-scientific-medical (ISM), short range devices (SRD) or similar

applications operating in the frequency range of 300 MHz to 930 MHz. In programmable user mode, the

transceiver can operate down to 27 MHz by employing an external VCO varactor diode.
