Radio frequency (RF) coax interface for full data rate controller area network (CAN) protocol signaling with low latency
First Claim
1. An electronic circuit, comprising:
- an input port configured to receive a first controller area network (CAN) signal;
a conversion circuit configured to convert the first CAN signal to a radio frequency (RF)-over-coax signal; and
a first output port coupled with a coaxial cable and configured to transmit the RF-over-coax signal over the coaxial cable.

Abstract
A method for implementing controller area network (CAN) communications between a plurality of CAN nodes using a single radio frequency (RF) coax cable is provided. In an aspect, a hardware interface (e.g., an electronic circuit) may be coupled to each of the plurality of CAN nodes. The hardware interface may receive a CAN signal from a first CAN node. The hardware interface may convert the CAN signal to a single RF signal and transmit the RF signal to a second CAN node over the single RF coax cable. Moreover, the hardware interface may transmit a CAN feedback signal received over the RF coax cable to the first CAN node. In an aspect, the hardware interface may include an amplitude modulation (AM) modulator, an AM detector, and a bandpass filter.
