DEVICES AND METHODS FOR TRANSMITTING USB TERMINATION SIGNALS OVER EXTENSION MEDIA

摘要

Devices and methods for providing SuperSpeed USB connections across an extension medium are provided. An upstream facing port device (UFP device) and a downstream facing port device (DFP device) are connected by an extension medium, and communicate via an extension protocol. The UFP device and the DFP device include switchable receiver termination circuitry. The receiver termination at the UFP device is enabled upon determining that a USB device coupled to the DFP device supports SuperSpeed communication, and the receiver termination at the DFP device is enabled upon determining that a host device coupled to the UFP device supports SuperSpeed communication.
