Abstract
An apparatus includes a bi-phase mark coded (BMC) input port configured to receive BMC signals from a universal serial bus (USB) cable. The apparatus further includes a threshold adjustment circuit configured to generate a threshold, and a comparator configured to compare an input BMC signal from the BMC input port and the threshold and based on the comparison, generate an adjusted input BMC signal. The threshold adjustment circuit is further configured to adjust the threshold based upon the input BMC signal.
