Home and building automation Pin Description General Description The TH71221 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 appli- cations operating in the frequency range of 300 MHz to 930 MHz. In programmable user mode, the trans- ceiver can operate down to 27 MHz by employing an external VCO varactor diode. bottom top IN_IFA IN_DEM INT2/PDO RSSI OUT_DEM OUT_DTA INT1 VCC_IF FS0/SDEN VEE_PLL VCC_PLL FS1/LD VEE_DIG LF TNK_LO TH71221 |
