<p>The present invention relates to a one chip radio receiving circuit for a vehicle and, more particularly, to a one chip radio receiving circuit for a vehicle, capable of transmitting a reception signal to an electronic control unit of the vehicle by receiving the reception signal transmitted from a remote keyless entry or a TPMS sensor device which is mounted on each tire installed in the vehicle and wirelessly transmits an amplitude-modulated or frequency-modulated reception signal. The one chip radio receiving circuit for the vehicle according to the present invention includes a signal conversion module which detects a received signal strength indication (RSSI) signal, a signal detection module which outputs a mode selection signal with regard to an amplitude modulation/frequency modulation output mode, an output module, and a control logic module which controls each module.</p> |
