ABSTRACT:
A differential line compensation apparatus is disclosed that has a first terminal to receive a first differential signal supplied by a first trace and a second terminal to receive a second differential signal supplied by a second trace. The apparatus has at least one detector to detect a first condition of a first signal at least related to the first differential signal, and a second condition of a second signal at least related to the second differential signal and to provide an output containing the results of the detections. A comparator is coupled to the at least one detector to receive and process the at least one output and to provide a control output. At least one delay controller receives the control output and applies a phase correction to a selected one of the first signal and the second signal. A corresponding method and system are also disclosed.
