Abstract
A relatively low frequency signal—e.g. RS-232—is coupled to and extracted from a communication link that carries both a high frequency continuous signal and burst mode signal having bursts occurring at one or more frequencies—e.g. SAS with OOB signaling. The communication link has a differential coupling which differentially couples onto a first pair of conductors a continuous signal at a continuous rate and a burst mode signal having bursts occurring at one or more frequencies. The communication link also has a common mode coupling which common mode couples a second signal onto the first pair of conductors. A high pass filter coupled to the first pair of conductors extracts the continuous signal and the burst mode signal from the first pair of conductors. A low pass filter coupled to the first pair of conductors extracts the second signal from the first pair of conductors.
