Differential signal reversion and correction circuit and method thereof

A differential signal reversion and correction circuit, comprising:

• two interconnected nodes;
• and
• a data frame sending module and a reversion control signal generating module disposed between the two interconnected nodes,
• the data frame sending module, including:
• a first input port, a second input port, a second output port, a third input port, and a third output port, the first input port is connected to a P line and an N line through a first buffer, the second input port, the second output port, the third input port, and the third output port are connected to each other in parallel and then are connected to the P line and the N line respectively;
• and
• the reversion control signal generating module, including:
• a second buffer connected to the P line and the N line,
• a comparator connected in series to the second buffer, and
• a control link, the control link including an uplink and a downlink, wherein
• the uplink is a first control switch, wherein an input of the first control switch is disposed at a configuring module which is positioned between the buffer and the comparator, the first control switch is connected in series to the configuring module, and an output of the first control switch is connected to the P line and the N line respectively, and
• the downlink is a second control switch, wherein an input of the second control switch is disposed between the buffer and the comparator, and an output of the second control switch is connected to the P line and the N line respectively.
