Abstract
Systems and methods are described for a reduced peak EMI bus using variable bit rate spreading. A method for reducing radiated Electro-Magnetic Interference from a wire communication bus transferring data between one or more physically separate modules or units comprises changing a data clock period controlling a rate of data bits on a communications bus. A Distributed Systems Interface communication bus data transmission protocol includes: alternating a data bit-rate between a first bit-rate and a second bit-rate on a bit-by-bit basis; transmitting a bit over the distributed systems interface communication bus according to the alternating data bit-rate; and varying a difference between the first bit-rate and the second bit-rate.
