COMMUNICATION DEVICE, CAPACITIVE DETECTION DEVICE AND EQUIPMENT PROVIDED WITH SUCH A DETECTION DEVICE

摘要

The present invention relates to a communication device (200) intended to be implemented with a communication bus in differential mode comprising at least two differential lines (102,104) for conveying a first signal (110) in differential mode between at least two modules differential communication (1061,1062), characterized in that it further comprises: -at least one transmitter (202) in common mode, for injecting the same second signal (210), said in common mode, alternating, on each said at least two differential lines (102,104), at a point on said communication bus; and at least one receiver (206) in common mode, for receiving said second signal (210), at another point of said communication bus.
