Abstract
Briefly, a method, apparatus and system for managing power corresponding to a differential serial communication link that has a link width defined for example by one or more lanes wherein the lanes are adapted to communicate clock recovery information in a data stream, determines, during normal operating conditions, such as conditions other than power on, reset or link fault conditions, a desired link width for the serial communication link and then changes the link width accordingly.
