Abstract
In one embodiment, a retimer device includes a receiver to receive data from a first device via a data link, retimer circuitry to recover a clock phase from the received data, and prepare a new copy of the received data sampled by a clean clock based on the recovered clock phase, a transmitter to transmit the new copy to a second device via the data link, wherein the receiver is configured to receive an in-band standby signal from the first device having a given pattern in a physical layer of the signal, activate a power saving mode of the retimer device responsively to the standby signal having the given pattern in the physical layer of the standby signal, receive an in-band wakeup signal from the first device, and initiate an exit from the power saving mode to power up the retimer device responsively to the wakeup signal.
