Abstract

The invention relates to a signal transmission and conversion circuit which comprises a first comparator, a fourth comparator, a third comparator, a fourth comparator, a fourth comparator, a fifth comparator, a sixth comparator, a fourth comparator, a fourth comparator, a fifth comparator, a sixth comparator and a seventh comparator. The eleventh input end is used for being connected with a forward signal input end, and the twelfth input end is connected with a first reference voltage. The first comparator is provided with a forty-first input end, a forty-second input end and a forty-first output end, the forty-first input end is used for being connected with the eleventh output end, and the forty-second input end is connected with a first reference voltage, and the third comparator is provided with a thirty-first input end, a thirty-second input end and a thirty-first output end. The first comparator is provided with a thirty-first input end and a thirty-second input end, the thirty-first input end is used for connecting a reverse signal input end, the thirty-second input end is connected with a first reference voltage, the second comparator is provided with a twenty-first input end, a twenty-second input end and a twenty-first output end, the twenty-first input end is used for connecting a thirty-first output end, the twenty-second input end is connected with the first reference voltage, and the twenty-second output end is connected with a Serial port signals can be converted into single-line transmission, the signal transmission level is improved, and the signal transmission distance is increased.

Description

technical field [0001] The invention relates to the field of signal processing, in particular to a signal transmission transformation circuit. Background technique [0002] The serial interface is a device that can convert the parallel data characters received from the CPU into continuous serial data streams and send them out, and at the same time convert the received serial data streams into parallel data characters for the CPU. Generally, the circuit that completes this function is called a serial interface circuit. The concept of serial communication (Serial Communications) is very simple, the communication method of sending and receiving bytes by the serial port bit by bit. [0003] At present, the transmission signal distance of the serial port signal transmission is short, and the signal interference is large. Contents of the invention [0004] Based on this, it is necessary to provide a signal transmission conversion circuit for the problems of short transmission ...
