Abstract: An active cable avoiding influence of RX power consumption, comprising: the host connection end, the device connection end and the data wire and the auxiliary wire located between them. The auxiliary wire consists of the main power wire and the auxiliary power wire, wherein, the main power wire is used for current transmission between the VBUS of the host and the device; the auxiliary wire, one end of it is located at the host connection end and connected with the main power wire, and another end at the device connection end and is used for supply power to the active component at the device connection end. The active cable disconnects an active module of the device connection end from the VBUS and also arranges the power module between the active component and the auxiliary wire.

Abstract: A low-speed signal conversion module for a DP interface is provided, including a protocol parsing module, an encoding module, a decoding module, a sending link, and a receiving link. The protocol parsing module is configured to parse a DP protocol, and send a low-speed signal of the DP interface to the encoding module, or send an output signal of the decoding module to the DP interface.
