Abstract

The invention discloses a circuit for two-way communication, and relates to the technical field of communications. The circuit is used for achieving the effect that a single access can conduct two-way data transmission at the same time. The circuit for two-way communication comprises a first buffer unit, a second buffer unit, a first resistor unit, a switch unit, a detection unit and a reference voltage source. A first input signal passes through the first buffer unit and the first resistor unit, and then a first output signal is output by the output end of the second buffer unit. A second input signal passes through the switch unit and a second resistor unit, and then a second output signal is output by the output end of the detection unit. The circuit can be used for two-way communication of data.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a circuit for two-way communication. Background technique [0002] With the continuous updating and upgrading of electronic products, people have higher and higher requirements for data transmission rate, and the data transmission between electronic products is mainly through ports. Wherein, each port includes at least one channel for data transmission, and each channel can only perform one-way communication at the same time, that is, each channel can only perform data transmission or data reception at the same time. [0003] Take Universal Serial Bus (USB for short) as an example. In the development process from USB2.0 to USB3.0, the USB2.0 port contains one channel, while the USB3.0 port contains three channels, that is, the original one channel in the USB2.0 port is increased to three. One channel in USB3.0 is dedicated to data or signal transmission, one channel is de...
