Abstract: Various configurations of high-speed data communication devices, e.g., repeaters, interfacing between a host and a peripheral, and methods of operating the same, are provided to improve the Remote Wake sequence. Repeaters include circuitry to detect the start of Resume signaling or the end of Resume, following initiation of Remote Wake. In an example, pull-up resistors coupled to upstream differential signal lines and a detection circuit with a current source are controlled to detect the start of Resume signaling. In another example, the upstream-side pull-resistors and an enable signal to an upstream-side transmitter are controlled to detect the end of Resume.
