Title:
ONE-CHIP RADIO RECEIVING CIRCUIT FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2015/076434
Kind Code:
A1
Abstract:
The present invention relates to a one-chip radio receiving circuit for a vehicle, and can be implemented in a one chip form such that the radio receiving circuit simultaneously receives an amplitude-modulated received signal and a frequency-modulated received signal transmitted from a wireless transmission device for a vehicle, like a TPMS sensor device or a remote control device, and then distinguishes the amplitude-modulated received signal from the frequency-modulated received signal through an RSSI signal and selectively outputs each received signal to an electronic control unit of a vehicle or outputs each received signal to the electronic control unit of the vehicle through an ASK output terminal and an FSK output terminal. Accordingly, the present invention can receive both the amplitude-modulated received signal and the frequency-modulated received signal through one radio receiving circuit, and thus, compared to a conventional circuit, the present invention has a reduced number of circuit components, thereby decreasing product costs.
