Common controller area network interface

A method of reconstructing an input data stream into an output data stream, comprising:

• capacitively isolating the input data stream to form a data stream of edge pulses;
• comparing the data stream of edge pulses to a ground signal;
• and
• latching the output data stream high upon a positive edge pulse and latching the output data stream low upon a negative edge pulse to create the output data stream.

An electronic interface for connecting to a network having a data stream placed on a bus high signal and a bus low signal, comprising:

• a synthesizing means coupled to the bus high signal and the bus low signal for synthesizing a ground from the bus high signal and bus low signal;
• an isolating means coupled to the synthesizing means for receiving the bus high signal from the synthesizing means and the ground from the synthesizing means and for generating an isolated bus high signal from the bus high signal;
• and
• a reconstruction means coupled to the isolating means for receiving an isolated bus high signal and a ground and for reconstructing the data stream by comparing the isolated bus high signal with the ground.
