Abstract
An apparatus, such as a re-driver, can include a receiver port coupled to a first link partner across a first link; a transmitter port coupled to a second link partner across a second link; and a power management (PM) controller implemented in hardware. The PM controller can detect a PM control signal, determine a PM state for the apparatus based on the PM control signal, and cause the apparatus to enter the PM state. The apparatus can transmit electrical signals to the second link partner based on the PM state. The PM management control signal can include a clock request, an electrical idle, a common mode voltage, or other electrical signal indicative of a PM link state change of a link partner coupled to the re-driver.
