Abstract

A transceiver circuit comprises a first transmitting end circuit, a first receiving end circuit, a first switching circuit and a processing circuit. The first transmitting end circuit comprises a first inductor and a second inductor, the second inductor is coupled between a first node and a second node, and one end of the first inductor is coupled to the second node. The first receiving end circuit is coupled to a third node. The first switching circuit is used for connecting or disconnecting the first node and the third node. When the transceiver circuit is operated in a transmitting mode, the processing circuit is used for controlling the first switching circuit to disconnect the first node and the third node, and when the transceiver circuit is operated in a receiving mode, the processing circuit is used for controlling the first switching circuit to connect the first node and the third node.

Description

technical field [0001] The present application relates to a transceiver circuit, in particular to a transceiver circuit applied to a high-speed input / output interface. Background technique [0002] In the application of traditional high-speed input / output interface, the transmission and reception of signals are usually performed by two independent circuits (eg, a transmitter circuit and a receiver circuit). However, in the new application of the integration of USB type-C and DP (DisplayPort), the transmitting circuit and the receiving circuit need to share the channel, which is difficult to realize with the traditional circuit structure. SUMMARY OF THE INVENTION [0003] An object of the content of the present application is to provide a transceiver circuit. The transceiver circuit includes a first transmitter circuit, a first receiver circuit, a first switch circuit and a processing circuit. The first transmitter circuit includes a first inductor and a second inductor, ...
